| 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.
|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 Solar and Heliospheric Observatory (SOHO).|

This year: "Astronomy in our day to day"
| * New date for Gaia launching
Desember 20 at 09:08:14* UT is the new date and time set for the launching of satellite Gaia.
ESA decided to postpone the launch of 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.
| * Weekend Solar Eclipse, 3rd November 2013
On Sunday morning, Nov. 3rd, the New Moon passed in front of the sun, producing a solar eclipse visible from the east Coast of North America to the western side of Africa.
| * Gaia sunshield deployment test successful, 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.

| * Preparing for comet ISON, 23 September 2013
ESA’s space missions are getting ready to observe an icy visitor to the inner Solar System: Comet ISON, which might also be visible in the night sky later this year as a naked eye object. The comet was discovered in images taken on 21 September 2012 by astronomers Artyom Novichonok and Vitali Nevski using a 40 cm-diameter telescope that is part of the International Scientific Optical Network, ISON.
| * Billion stars in the most accurate map of the Milky Way, September 3, 2013
Astronomers want to decipher the history of the Galaxy with the telescope 'Gaia'. The European Gaia telescope will map the Milky Way billions of stars. It seems to be many, however, account for only 1% of the stellar population of our Galaxy.
| * Fly your experiment to the edge of the Space, September 2, 2013
The opportunity to fly experiments high into the stratosphere or even to the edge of space is now open again for university students. Up to 10 teams will be selected to fly a balloon experiment during autumn 2014 or a rocket experiment in spring 2015.
| * Waking up to a new year, 19 August 2013
In the time it takes you to complete a single workday, or get a full night’s sleep, a small fireball of a planet 700 light-years away has already completed an entire year.
| * Dance of the X -Rays, 29 July 2013
Like car tail lights streaking through a busy city at night, this unique image records over a thousand movements made by ESA’s XMM-Newton space telescope as it shifts its gaze from one X-ray object to another.
| * Starburst to Star Bust, 25 July 2013
New observations from the ALMA telescope in Chile have given astronomers the best view yet of how vigorous star formation can blast gas out of a galaxy and starve future generations of stars of the fuel they need to form and grow.
| * Side by side Solar eruptions, 22nd July 2013
Two solar eruptions expand side-by-side into space in this movie, playing out in front of the ESA/NASA Solar and Heliospheric Observatory, SOHO, on 1–2 July 2013.
| * Ripped Apart by a Black Hole, 17th July 2013
New observations from ESO’s Very Large Telescope show for the first time a gas cloud being ripped apart by the supermassive black hole at the centre of the galaxy. The cloud is now so stretched that its front part has passed the closest point and is travelling away from the black hole at more than 10 million km/h, whilst the tail is still falling towards it.
| *Fly through a canyon on Mars, 16th July 2013
Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning colour movie from ESA’s Mars Express. Valles Marineris is not just the largest canyon on Mars, but at 4000 km long, 200 km wide and 10 km deep it is the largest in the entire Solar System.
| * World Premiere of IMAX® 3D Film Hidden Universe , July 1st 2013
The 3D production Hidden Universe has been released in IMAX® theatres and giant-screen cinemas around the globe, with world premieres on 28 June 2013 at Great Lakes Science Center in Cleveland, Ohio, USA, and on 29 June at the Tycho Brahe Planetarium in Copenhagen, Denmark. The film shows state-of-the-art telescopes in high-resolution time-lapse, mesmerising 3D versions of celestial structures, and a 3D simulation of the evolution of the Universe.
| * Three Planets in Habitable Zone of Nearby Star , June 25th 2013
A team of astronomers has combined new observations of Gliese 667C with existing data from HARPS at ESO’s 3.6-metre telescope in Chile, to reveal a system with at least six planets. A record-breaking three of these planets are super-Earths lying in the zone around the star where liquid water could exist, making them possible candidates for the presence of life. This is the first system found with a fully packed habitable zone.
| * The port of Barcelona from space, June 21th 2013
The Japanese ALOS satellite has photographed from space Barcelona, in the northeast coast of the Iberian Peninsula.
| * First woman in Space, Valentina , June 16th 2013
After the first human spaceflight by Yuri Gagarin, the selection of female cosmonaut trainees was authorised by the Soviet government, with the aim of ensuring the first woman in space was a Soviet citizen.
| * New Kind of Variable Star Discovered , June 12th 2013
Astronomers using the Swiss 1.2-metre Euler telescope at ESO’s La Silla Observatory in Chile have found a new type of variable star. The discovery was based on the detection of very tiny changes in brightness of stars in a cluster. The observations revealed previously unknown properties of these stars that defy current theories and raise questions about the origin of the variations.
| * Ten years at Mars; New global views plot the red planet's History , June 3rd, 2013
New global maps of Mars released on the 10th anniversary of the launch of ESA's Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.
