Comet Ison

 
Ison comet flew through the solar atmosphere but the encounter did not go well. 

Just before reaching perihelion the comet appeared to disintegrate. But after that was seen that a portion of it had survived the encounter. 

For the moment it is still not known what remains of the comet.

The article on the formation of relativistic jets in black holes,by a member of the Department published in Nature

It is known that black holes launch relativistic jets both in stellar-mass binary systems and at the centres of galaxies, in the so-called ‘quasars’. Although jets have been studied for decades, their composition has remained uncertain. Now, a work, published on Nature and led by researchers from the University of Barcelona, the German headquarters of the European Southern Observatory (ESO) and Curtin University (Australia), presents the detection of atomic nuclei in the relativistic jets from the black hole binary system 4U 1630-47.

Gaia launch postponement update

Yesterday, the decision was taken to postpone the launch of ESA’s Gaia mission after a technical issue was identified in another satellite already in orbit.

Gaia shares some of the components involved in this technical issue and prompt notification of this problem has allowed engineers working on the final preparations for Gaia’s launch to take additional precautionary measures.

Gaia sunshield deployment test successful

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.
