"Iluminando el lado oscuro del universo" the book written by Roberto Emparan, 02/02/2018 El descubrimiento de las ondas gravitatorias —el peculiar sonido de dos agujeros negros que chocan y se funden uno con otro— cambiará nuestra manera de imaginar el universo: a partir de ahora escucharemos su banda sonora. ¿Qué significa este hallazgo histórico, y cómo hemos llegado hasta él? Este es el relato de una fascinante odisea que comenzó hace más de cien años con un joven llamado Albert Einstein. Roberto Emparán, uno de nuestros físicos más reconocidos internacionalmente en el campo de la gravedad, los agujeros negros y la teoría de supercuerdas, ha compuesto una historia de ciencia en acción, que nos invita a recorrer en compañía de sus protagonistas, con sus defectos y sus emociones, en la búsqueda de respuestas a preguntas fundamentales. Una guía de viaje accesible, estimulante y fiable hacia las sorprendentes ideas sobre el tiempo y el espacio que hace un siglo se imaginaron y hoy por fin hemos conseguido demostrar. Preparémonos para iluminar el lado oscuro del universo y disfrutar así de la extraordinaria música de la oscuridad cósmica. |

Selected asteroids detected by Gaia between August 2014 and May 2016 , 30/11/2017 While scanning the sky, ESA's Gaia mission maps not only the stellar content of our Galaxy, but also the Solar System's asteroid population. This visualisation shows the detection by Gaia of more than 13 000 asteroids as the spacecraft (represented by the pale blue dot) scanned the sky between August 2014 and May 2016. This is a subset of the total number of asteroids seen by Gaia – the sample shown here is of bright asteroids that have been detected more than ten times during the period. The corresponding data for the position on the sky for each detection of every asteroid – the epoch astrometry – will be included in Gaia's Data Release 2, the second intermediate data release from the mission, expected in April 2018. |

An asteroid coming from a distant star is visiting the Solar System, 07/11/2017 The Solar System is home to a huge number of asteroids. Most of them lie between the orbits of Mars and Jupiter. The first asteroid was discovered in 1801; by 1900, nearly 500 were known, and modern techniques for surveying the skies have led to orbit determinations of hundreds of thousands of them. One of the telescopes that explores the sky taking frequent images over large areas and looking for streaks left by a moving asteroid is PANSTARRS 1, located in Hawaii. On October 20th, one of the many new asteroids that are discovered every day was detected by PANSTARRS, but this one showed a very peculiar behavior: as more observations were collected to determine an orbit, it became clear that it was moving much faster than any other known object in the Solar System. This meant that this new asteroid, designated as A/2017 U1, was not a Solar System object, but it had come from another star. |

Odd planetary system around fast-spinning star doesn't quite fit existing models of planet formation, 12/07/2017 Max Planck Institute for Astronomy / Astronomy & Astrophysics Astronomers have discovered a rare, warm, massive Jupiter-like planet orbiting a star that is rotating extremely quickly. The discovery raises puzzling questions about planet formation – neither the planet's comparatively small mass nor its large distance from its host star are expected according to current models. |

No Universe without Big Bang, 15/06/2017 According to Einstein’s theory of relativity, the curvature of spacetime was infinite at the big bang. In fact, at this point all mathematical tools fail, and the theory breaks down. However, there remained the notion that perhaps the beginning of the universe could be treated in a simpler manner, and that the infinities of the big bang might be avoided. Now scientists at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and at the Perimeter Institute in Canada have been able to use better mathematical methods to show that these ideas cannot work. The big bang, in its complicated glory, retains all its mystery. |

Will Earth-like planets be found to have Earth-like oceans?,, 21/04/2017 For a planetary surface to boast extensive areas of both land and water, a delicate balance must be struck between the volume of water it retains and the capacity of its oceanic basins. Each of these two quantities may vary substantially across the full spectrum of water-bearing worlds. Why the Earth’s values are so well balanced is an unresolved and long-standing conundrum. In a paper published in the Monthly Notices of the Royal Astronomical Society (Ed. Oxford University Press) the author, Fergus Simpson of the Institute of Cosmos Science at the University of Barcelona, has constructed a statistical model – based on Bayesian probability – to predict the division between land and water on habitable exoplanets. |

Spinning Black Hole Swallowing Star Explains Superluminous Event, 12/12/2016 An extraordinarily brilliant point of light seen in a distant galaxy, and dubbed ASASSN-15lh, was thought to be the brightest supernova ever seen. But new observations from several observatories, including ESO, have now cast doubt on this classification. Instead, a group of astronomers propose that the source was an even more extreme and very rare event — a rapidly spinning black hole ripping apart a passing star that came too close. |

Unexpected Excess of Giant Planets in Star Cluster, 17/06/2016 An international team of astronomers have found that there are far more planets of the hot Jupiter type than expected in a cluster of stars called Messier 67. This surprising result was obtained using a number of telescopes and instruments, among them the HARPS spectrograph at ESO’s La Silla Observatory in Chile. The denser environment in a cluster will cause more frequent interactions between planets and nearby stars, which may explain the excess of hot Jupiters. |

Aging Star’s Weight Loss Secret Revealed, 15 November 2015 A team of astronomers using ESO’s Very Large Telescope (VLT) has captured the most detailed images ever of the hypergiant star VY Canis Majoris. These observations show how the unexpectedly large size of the particles of dust surrounding the star enable it to lose an enormous amount of mass as it begins to die. This process, understood now for the first time, is necessary to prepare such gigantic stars to meet explosive demises as supernovae. |

Venus, Jupiter and Marte very close at dawn, 27 de octubre Although any morning in late October is a good time to look at these planets, the six day stretch from Oct. 24th through the 29th is the best. That's because during this time, the triangle of planets will shrink until it is less than five degrees wide. By the time October comes to an end, the planetary triangle will start breaking apart. But there are still two dates of special interest: Nov. 6th and 7th. On those increasingly wintry mornings, the crescent Moon will swoop in among the dispersing planets. |

Outbursts from a newborn star, 13 October The object lies in the constellation of Orion (The Hunter) in a dense molecular star-forming region, not far from the famous Horsehead Nebula. In regions like this, clouds of dust and gas collapse under the force of gravity, spinning faster and faster and becoming hotter and hotter until a young star ignites at the cloud’s centre. Any leftover material swirling around the newborn protostar comes together to form an accretion disc that will, under the right circumstances, eventually evolve to form the base material for the creation of planets, asteroids and comets. |

A Shy Galactic Neighbour, 16 September The Sculptor Dwarf Galaxy, pictured in this new image from the Wide Field Imager camera, installed on the 2.2-metre MPG/ESO telescope at ESO’s La Silla Observatory, is a close neighbour of our galaxy, the Milky Way. Despite their close proximity, both galaxies have very distinct histories and characters. This galaxy is much smaller and older than the Milky Way, making it a valuable subject for studying both star and galaxy formation in the early Universe. However, due to its faintness, studying this object is no easy task. |

Jupiter Twin Discovered Around Solar Twin, 15 July 2015 An international group of astronomers has used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in shaping the architecture of planetary systems. The existence of a Jupiter-mass planet in a Jupiter-like orbit around a Sun-like star opens the possibility that the system of planets around this star may be similar to our own Solar System. HIP 11915 is about the same age as the Sun and, furthermore, its Sun-like composition suggests that there may also be rocky planets orbiting closer to the star. |

Hubble Telescope Detects ‘Sunscreen’ Layer on Distant Planet ,12 June Hubble Space Telescope has detected a stratosphere, one of the primary layers of Earth’s atmosphere, on a massive and blazing-hot exoplanet known as WASP-33b. The presence of a stratosphere can provide clues about the composition of a planet and how it formed. This atmospheric layer includes molecules that absorb ultraviolet and visible light, acting as a kind of “sunscreen” for the planet it surrounds. Until now, scientists were uncertain whether these molecules would be found in the atmospheres of large, extremely hot planets in other star systems. |

A Celestial Butterfly Emerges from its Dusty Cocoon,10 June Some of the sharpest images ever made with ESO’s Very Large Telescope (VLT) have, for the first time, revealed what appears to be an ageing star giving birth to a butterfly-like planetary nebula. These observations of the red giant star L2 Puppis, from the ZIMPOL mode of the newly installed SPHERE instrument, also clearly showed a close companion. The dying stages of stars continue to pose astronomers with many riddles, and the origin of such bipolar nebulae, with their complex and alluring hourglass figures, doubly so. This new imaging mode means that the VLT is currently the sharpest astronomical direct imaging instrument in existence. |

Meteor Shower in Broad Daylight ,5 June Earth is entering a stream of debris from an unknown comet, and this is causing one of the most intense meteor showers of the year. Ironically, most sky watchers won't notice because the shower peaks in broad daylight. We only know it's happening because a radar in Canada is picking up echoes from meteoroids streaking through the blue sky overhead. Astronomers call these meteors "Arietids" because they emerge from the constellation Aries not far from the June sun. |

Colliding Stars Explain Enigmatic Seventeenth Century Explosion 23 March, New observations made with APEX and other telescopes reveal that the star that European astronomers saw appear in the sky in 1670 was not a nova, but a much rarer, violent breed of stellar collision. It was spectacular enough to be easily seen with the naked eye during its first outburst, but the traces it left were so faint that very careful analysis using submillimetre telescopes was needed before the mystery could finally be unravelled more than 340 years later. The results appear online in the journal Nature on 23 March 2015. |

Unusual comet dive-bombs the Sun, 20 February, Astronomers are puzzling over a comet that passed "insanely close" to the sun on Feb. 19th. At first glance it appeared to be a small object, not much bigger than a comet-boulder, doomed to disintegrate in the fierce heat. Instead, it has emerged apparently intact and is actually brightening as it recedes from the sun. Unofficially, the icy visitor is being called "SOHO-2875," because it is SOHO's 2,875th comet discovery. |

Lovejoy magnificent, 22 January 2015, Comet Lovejoy is still on the way to the perihelion of its orbit, which will take place on 30 January. Although at this time is moving away from Earth, it continues being an object visible to the naked eye (magnitude around 4) due its high activity. From an astronomical perspective these days we are living the most spectacular moments that the comet can offer. Moving from state of hibernation to a frenetic activity due to increased solar radiation. This activity is visible on its comma and on the tail. + info: Article "cometa Lovejoy" from Miquel Serra Ricart, IAC astrophysicist on the blog Vía Láctea s/n. *Links*:

Geminid Meteor Shower, 1 December, Earth is entering a stream of gravelly debris from "rock comet" 3200 Phaethon, source of the annual Geminid meteor shower. On the night of Nov. 30-Dec. 1, NASA's network of all-sky cameras detected three Geminid fireballs over the USA (see the image). This specimen from the desert southwest was clearly visible despite the glare from the waxing gibbous Moon. Meteor sightings will increase in the nights ahead as Earth plunges deeper into the debris stream. Forecasters expect peak rates to occur on Dec. 13-14, when dark-sky observers in both hemispheres could see as many as 120 meteors per hour. |

Planet-forming Lifeline Discovered in a Binary Star System, 30 October, For the first time, researchers using ALMA have detected a streamer of gas flowing from a massive outer disc toward the inner reaches of a binary star system. This never-before-seen feature may be responsible for sustaining a second, smaller disc of planet-forming material that otherwise would have disappeared long ago. Half of Sun-like stars are born in binary systems, meaning that these findings will have major consequences for the hunt for exoplanets. The results are published in the journal Nature on 30 October 2014. |

NASA Mission Points to Origin of “Ocean of Storms” on Earth’s Moon, 1 October 2014, Early theories suggested the craggy outline of a region of the moon’s surface known as Oceanus Procellarum, or the Ocean of Storms, was caused by an asteroid impact. If this theory had been correct, the basin it formed would be the largest asteroid impact basin on the moon. However, mission scientists studying GRAIL data believe they have found evidence the craggy outline of this rectangular region -- roughly 1,600 miles (2,600 kilometers) across -- is actually the result of the formation of ancient rift valleys. |

Violent Origins of Disc Galaxies Probed by ALMA 17 Septembre 2014, For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers using ALMA and a host of other radio telescopes have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe. |

Gaia discovers its first supernova, 12 September, While scanning the sky to measure the positions and movements of stars in our Galaxy, Gaia has discovered a supernova, called Gaia 14aaa, in a galaxy located about 500 million light years away. The sudden rise in the galaxy brightness detected between one observation on August 30th and another one made one month before, indicated the possibility of a supernova. This galaxy showed a a 6 factor change of its brightness. Position measurements were made to corroborate the hypothesis that it was a supernova and to reject the option of outbursts caused by the mass-devouring supermassive black hole at the galaxy centre. The position of the bright spot of light was slightly offset from the galaxy’s core, suggesting that it was unlikely to be related to a central black hole. The astronomers analysed the light spectrum to seek signatures of various chemical elements typical of those kind of phenomenon. Complementary observations were made with terrestrial Telescopes such as the Isaac Newton Telescope (INT) and the Liverpool Telescope, both placed at the La Palma Island. All information confirmed that the phenomenon was a supernova and also indicated its nature: a Type Ia supernova, correspondent to the explosion of a white dwarf locked in a binary system with a companion star. It was just the firts discovery of the many that will occur during the 5 years of the mission. More information about the supernova GaiaUB Group Gaia-ESA Follow the mision with the GaiaApp Gaia is an ESA mission to survey one billion stars in our Galaxy and local galactic neighbourhood in order to build the most precise 3D map of the Milky Way and answer questions about its origin and evolution. It was launched on 19 December 2013.

Nearby M33 galaxy blossoming with star birth 28 July 2014, The spiral galaxy M33, also known as the Triangulum Galaxy, is one of our closest cosmic neighbours, just three million light-years away. Home to some forty billion stars, it is the third largest in the Local Group of galaxies after the Andromeda Galaxy (M31) and our own Milky Way. This image, from ESA's Herschel space observatory, shows M33 in far-infrared light, revealing the glow of cosmic dust in the interstellar medium that permeates the galaxy. The patchy, disorganised structure of M33's spiral arms resembles a tuft of wool, leading astronomers to classify it as a flocculent spiral galaxy. |

Camelopardalid meteor shower 26 May That's not what a meteor storm looks like. On May 24th, as predicted, Earth passed through a stream of debris from Comet 209P/LINEAR, and the encounter did produce a number of fine meteors. However, contrary to some forecasts, there was no intense outburst. Typical naked-eye meteor rates were no more than 5 or 10 per hour, a far cry from the "meteor storm" some headlines anticipated. |

Length of Exoplanet Day Measured for First Time 30 April Observations from ESO’s Very Large Telescope (VLT) have, for the first time, determined the rotation rate of an exoplanet. Beta Pictoris b has been found to have a day that lasts only eight hours. This is much quicker than any planet in the Solar System — its equator is moving at almost 100 000 kilometres per hour. This new result extends the relation between mass and rotation seen in the Solar System to exoplanets. Similar techniques will allow astronomers to map exoplanets in detail in the future with the European Extremely Large Telescope (E-ELT). |

Total Lunar Eclipse 15 April The entire event is visible from both North and South America. Observers in the western Pacific miss the first half of the eclipse because it occurs before moonrise. Likewise most of Europe and Africa experience moonset just as the eclipse begins. None of the eclipse is visible from north/east Europe, eastern Africa, the Middle East or Central Asia.. NASA offered live via its website the event. Those who have not been able to enjoy such a spectacle, can see the best images that different observers have uploaded at the group that created NASA in flick called "NASA Lunar Eclipse Group". |

| The DAM Gaia group on the fair «Live research»
The Gaia group of our Department has participated on the fair «Live research». The fair is an exhibition of contemporary research organized annually by the Barcelona Science Park (Parc Científic de Barcelona) in collaboration with the University of Barcelona (UB).
The aim of the fair is to improve scientific understanding and awareness in our society by presenting research that is currently being undertaken in Barcelona to the public, and for real researchers to explain to the general public the main characteristics of the scientific method.
At the same time the Fair presents research being performed in Barcelona in a coordinated way, exhibiting projects of research groups from different R&D institutions and centres in the city. These bring part of their laboratories to the Fair so that members of the public can interact with the instruments that are central to research in Barcelona and ask whatever questions they fancy. Dates: 8-10 April 2014
Place: Aula Capella of the UB Historic Building
Time: From 10 a.m. to 2 p.m.
and 4 p.m. to 8 p.m. Free entrance from 4 p.m.

Faraway Moon or Faint Star? Possible Exomoon Found 10 April NASA-funded researchers have spotted the first signs of an "exomoon," and though they say it's impossible to confirm its presence, the finding is a tantalizing first step toward locating others. The discovery was made by watching a chance encounter of objects in our galaxy, which can be witnessed only once. "We won't have a chance to observe the exomoon candidate again," said David Bennett of the University of Notre Dame, Ind., lead author of a new paper on the findings appearing in the Astrophysical Journal. "But we can expect more unexpected finds like this." The international study is led by the joint Japan-New Zealand-American Microlensing Observations in Astrophysics (MOA) and the Probing Lensing Anomalies NETwork (PLANET) programs, using telescopes in New Zealand and Tasmania. Their technique, called gravitational microlensing, takes advantage of chance alignments between stars. When a foreground star passes between us and a more distant star, the closer star can act like a magnifying glass to focus and brighten the light of the more distant one. These brightening events usually last about a month.. |

Galactic Serial Killer 2 April This new image from the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile shows two contrasting galaxies: NGC 1316, and its smaller neighbour NGC 1317. These two are quite close to each other in space, but they have very different histories. The small spiral NGC 1317 has led an uneventful life, but NGC 1316 has engulfed several other galaxies in its violent history and shows the battle scars. |

Redefining Solar System's Edge 26 March The solar system has a new most-distant family member. Scientists using ground based observatories have discovered an object that is believed to have the most distant orbit found beyond the known edge of our solar system. Named 2012 VP113, the observations of the object -- possibly a dwarf planet -- were obtained and analyzed with a grant from NASA. A dwarf planet is an object in orbit around the sun that is large enough to have its own gravity pull itself into a spherical, or nearly round, shape. |

First Ring System Around Asteroid 26 March Observations at many sites in South America, including ESO’s La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System — after the much larger planets Jupiter, Saturn, Uranus and Neptune — to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris. |

VLT Spots Largest Yellow Hypergiant Star 12 March ESO’s Very Large Telescope Interferometer has revealed the largest yellow star — and one of the ten largest stars found so far. This hypergiant has been found to measure more than 1300 times the diameter of the Sun, and to be part of a double star system, with the second component so close that it is in contact with the main star. Observations spanning over sixty years, some from amateur observers, also indicate that this rare and remarkable object is changing very rapidly and has been caught during a very brief phase of its life. |

Largest Solar System Moon Detailed in Geologic Map, 12 February A group of scientists led by Geoffrey Collins of Wheaton College has produced the first global geologic map of Ganymede, Jupiter’s seventh moon. The map combines the best images obtained during flybys conducted by NASA's Voyager 1 and 2 spacecraft (1979) and Galileo orbiter (1995 to 2003) and is now published by the U. S. Geological Survey as a global map. It technically illustrates the varied geologic character of Ganymede’s surface and is the first global, geologic map of this icy, outer-planet moon. |

Gaia comes into focus, 6 February ESA’s billion-star surveyor Gaia is slowly being brought into focus. This test image shows a dense cluster of stars in the Large Magellanic Cloud, a satellite galaxy of our Milky Way. Once Gaia starts making routine measurements, it will generate truly enormous amounts of data. To maximise the key science of the mission, only small ‘cut-outs’ centred on each of the stars it detects will be sent back to Earth for analysis. This test picture, taken as part of commissioning the mission to ‘fine tune’ the behaviour of the instruments, is one of the first proper ‘images’ to be seen from Gaia, but ironically, it will also be one of the last. Before Gaia is ready to enter its five-year operational phase the telescopes must be aligned and focused, ad the instruments calibrated, a painstaking procedure that will take several months. |

Comet ISON is brightening rapidly as it plunges into the sun's atmosphere. At closest approach on Nov. 28th the comet will be little more than a million kilometers above the sun's fiery surface. Temperatures around ISON's icy nucleus could rise as high as 5000º F. No one knows if it can survive that kind of baking--but if it does, it could emerge as a splendid naked-eye comet in early December. Right now, the best views of the comet are coming from the. | |

* , 18 October 2013 Ahead of its launch on 20 November 2013, Gaia has passed its critical sunshield deployment test. The sunshield has been fabricated by the Spanish company SENER. During the test at Europe's spaceport in Kourou the shield's twelve carbon fibre folding frames were opened successfully in the cleanroom. As the Deployable Sunshield assembly (DSA) was not designed to support its own weight in the one-g environment at Earth's surface, support cables and counterweights attached to the shield provided a realistic test environment. In space the 10.5 metre diameter sunshield will shade the spacecraft's telescope from the sun. It will also help to provide a stable and low temperature environment. |

* Discovery of the First Isolated Compact Elliptical (cE) Galaxy, 24th April 2013 Compact ellipticals (cEs) are a rare type of dwarf galaxy, possessing small effective radii and high central surface brightnesses. The best example is M32, a companion to the nearby Andromeda Galaxy. All of those found to date are close to massive galaxies, so many astronomers believe that their unusual features are the consequence of the tidal stripping of a much larger progenitor galaxy by the very massive host. Others, however, have argued that cEs are formed in the same manner as all elliptical galaxies, and are simply the rare low-mass examples. |

* Even Brown Dwarfs May Grow Rocky Planets, 30th of November: Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time found that the outer region of a dusty disc encircling a brown dwarf contains millimetre-sized solid grains like those found in denser discs around newborn stars. The surprising finding challenges theories of how rocky, Earth-scale planets form, and suggests that rocky planets may be even more common in the Universe than expected. |
|
 |
* Biggest Black Hole Blast Discovered, 28th November: Astronomers using ESO’s Very Large Telescope (VLT) have discovered a quasar with the most energetic outflow ever seen, at least five times more powerful than any that have been observed to date. Quasars are extremely bright galactic centres powered by supermassive black holes. Many blast huge amounts of material out into their host galaxies, and these outflows play a key role in the evolution of galaxies. But, until now, observed quasar outflows weren’t as powerful as predicted by theorists. |
|
 |
* Solar Minimum; Solar Maximum, 26th November: The picture on the left shows a calm sun from Oct. 2010. The right side, from Oct. 2012, shows a much more active and varied solar atmosphere as the sun moves closer to peak solar activity, a peak known as solar maximum, predicted for 2013. Both images were captured by NASA's Solar Dynamics Observatory (SDO) observing light emitted from the 1 million degree plasma, which is a good temperature for observing the quiet corona. |
|
 |
* Dwarf Planet Makemake Lacks Atmosphere, 21st of november: Astronomers have used three telescopes at ESO’s observatories in Chile to observe the dwarf planet Makemake as it drifted in front of a distant star and blocked its light. The new observations have allowed them to check for the first time whether Makemake is surrounded by an atmosphere. This chilly world has an orbit lying in the outer Solar System and was expected to have an atmosphere like Pluto (eso0908), but this is now shown not to be the case. The scientists also measured Makemake’s density for the first time. |
|
 |
* Lost in Space: Rogue Planet Spotted?, 14 de novembre: Astronomers using ESO’s Very Large Telescope and the Canada-France-Hawaii Telescope have identified a body that is very probably a planet wandering through space without a parent star. This is the most exciting free-floating planet candidate so far and the closest such object to the Solar System at a distance of about 100 light-years. Its comparative proximity, and the absence of a bright star very close to it, has allowed the team to study its atmosphere in great detail. This object also gives astronomers a preview of the exoplanets that future instruments aim to image around stars other than the Sun. |

 |
* Proba-2 soaks up three solar eclipses, 14th November: ESA’s Sun-watching Proba-2 satellite experienced three partial solar eclipses last night while lucky observers watching from northern Australia were treated to a total solar eclipse. |
|
 |
* Total Solar Eclipse, 13th of november: A total eclipse of the Sun was visible from within a narrow corridor that traverses Earth's Southern Hemisphere. The path of the Moon's umbral shadow began in northern Australia and crossed the South Pacific Ocean with no other landfall. More information |

* Stars Ancient and Modern?, 31th October: Globular star clusters are among the oldest objects in the Universe, and NGC 6362 cannot hide its age in this picture. The many yellowish stars in the cluster have already run through much of their lives and become red giant stars. . |
|
 |
* NGC 4178: Revealing a Mini-Supermassive Black Hole, 24th October: One of the lowest mass supermassive black holes ever observed in the middle of a galaxy has been identified, thanks to NASA's Chandra X-ray Observatory and several other observatories. |
|
 |
* The Solar System’s grandest canyon, 22th October: Earth’s Grand Canyon inspires awe for anyone who casts eyes upon the vast river-cut valley, but it would seem nothing more than a scratch next to the cavernous scar of Valles Marineris that marks the face of Mars. |
|

* The ESA presents the Gaia mission in which participate 30 UB researchers, 30th October: The Gaia mission begins its countdown. In one year, it will take place the launch of this satellite of the European Space Agency (ESA) that will map more than a thousand million stars throughout our Galaxy with an unparalleled precision, and will test the theories of formation and evolution of our Galaxy. The main object of this mission is to create the most accurate galactic census of the Milky Way. More than 400 scientists collaborate in this project, and thirty researchers and technicians from the Department of Astronomy and Meteorology of the University of Barcelona have performed a really important role in the conception and design of the instrument and in processing and simulating the mission's data.

 |
* Surprising Spiral Structure Spotted by ALMA, 10th October: Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered a totally unexpected spiral structure in the material around the old star R Sculptoris. This is the first time that such a structure, along with an outer spherical shell, has been found around a red giant star. It is also the first time that astronomers could get full three-dimensional information about such a spiral. The strange shape was probably created by a hidden companion star orbiting the red giant. . |

- Uranus auroras glimpsed from Earth, 25th of april:
for the first time, scientists have captured images of auroras above the giant ice planet Uranus, finding further evidence of just how peculiar a world that distant planet is. Detected by means of carefully scheduled observations from the Hubble Space Telescope, the newly witnessed Uranian light show consisted of short-lived, faint, glowing dots – a world of difference from the colorful curtains of light that often ring Earth's poles. - Herschel spots comet massacre around nearby star,13 de abril:
ESA's Herschel Space Observatory has studied the dusty belt around the nearby star Fomalhaut. The dust appears to be coming from collisions that destroy up to thousands of icy comets every day.

- Space Observations of Mercury Transits Yield Precise Solar Radius, 20th of march:
a group of scientists from Hawaii, Brazil and California has measured the diameter of the Sun with unprecedented accuracy by using a spacecraft to time the transits of the planet Mercury across the face of the Sun in 2003 and 2006. They measured the Sun’s radius as 696,342 km (432,687 miles) with an uncertainty of only 65 km (40 miles). This was achieved by using the solar telescope aboard a NASA satellite, thereby bypassing the blurring caused by Earth’s atmosphere that occurs when observations are made from the ground. - Powerhouse in the Crab Nebula, March 30:
the pulsar at the centre of the famous Crab Nebula is a veritable bundle of energy. This was now confirmed by the two MAGIC (Major Atmospheric Gamma-Ray Imaging Cherenkov) Telescopes on the Canary island of La Palma. They observed the pulsar in the area of very high energy gamma radiation from 25 up to 400 gigaelectronvolts (GeV), a region that was previously difficult to access with high energy instruments, and discovered that it actually emits pulses with the maximum energy of up to 400 GeV -- 50 to 100 times higher than theorists thought possible.

This new view shows a stellar nursery called NGC 3324. It was taken using the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile. - BEX: Glimpses of the Interstellar Material Beyond our Solar System, 1 february
A great magnetic bubble surrounds the solar system as it cruises through the galaxy. The sun pumps the inside of the bubble full of solar particles that stream out to the edge until they collide with the material that fills the rest of the galaxy, at a complex boundary called the heliosheath. On the other side of the boundary, electrically charged particles from the galactic wind blow by, but rebound off the heliosheath, never to enter the solar system. Neutral particles, on the other hand, are a different story. They saunter across the boundary as if it weren't there, continuing on another 7.5 billion miles for 30 years until they get caught by the sun's gravity, and sling shot around the star.

Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars. - Planets around stars are the rule rather than the exception,11 January 2012:
An international team, including three astronomers from the European Southern Observatory (ESO), has used the technique of gravitational microlensing to measure how common planets are in the Milky Way. After a six-year search that surveyed millions of stars, the team concludes that planets around stars are the rule rather than the exception. The results will appear in the journal Nature on 12 January 2012. - El Gordo — A “Fat” Distant Galaxy Cluster, 10 January 2012:
An extremely hot, massive young galaxy cluster — the largest ever seen in the distant Universe — has been studied by an international team using ESO’s Very Large Telescope (VLT) in the Atacama Desert in Chile along with NASA's Chandra X-ray Observatory and the Atacama Cosmology Telescope. The new results are being announced on 10 January 2012 at the 219th meeting of the American Astronomical Society in Austin, Texas.

- Space Mountain Produces Terrestrial Meteorites, Dec. 30, 2011:
When NASA's Dawn spacecraft entered orbit around giant asteroid Vesta in July, scientists fully expected the probe to reveal some surprising sights. But no one expected a 13-mile high mountain, two and a half times higher than Mount Everest, to be one of them. - VLT founds a star with a record speed rotation. 05/12/2011.
The ESO Very Large Telescope at Cerro Paranal (Chile), detected the star with fastest rotation known. This young, massive and bright star is situated in our neighboring galaxy the Large Magellanic Cloud, about 160 000 light years from Earth. Astronomers believe that could have a violent past and would have been ejected from a binary star system after the explosion of his companion. - NASA's Voyager Hits New Region at Solar System Edge, 05/12/2011. NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space. Data obtained from Voyager over the last year reveal this new region to be a kind of cosmic purgatory. In it, the wind of charged particles streaming out from our sun has calmed, our solar system's magnetic field is piled up, and higher-energy particles from inside our solar system appear to be leaking out into interstellar space. NASA's Kepler Mission Confirms Its First Planet in Habitable Zone of Sun-like Star
- NASA's Kepler mission has confirmed its first planet in the "habitable zone,"05/12/2011 NASA's Kepler mission has confirmed its first planet in the "habitable zone," the region where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Ten of these candidates are near-Earth-size and orbit in the habitable zone of their host star. Candidates require follow-up observations to verify they are actual planets
- Study: Giant Super-Earths made of diamond are possible, 05/12/2011. A planet made of diamonds may sound lovely, but you wouldn’t want to live there.A new study suggests that some stars in the Milky Way could harbor “carbon super-Earths” – giant terrestrial planets that contain up to 50 percent diamond. But if they exist, those planets are likely devoid of life as we know it.
