Thu, 13 Oct 2016 14:00:00 UTAstronomers using data from the NASA/ESA Hubble Space Telescopes and other telescopes have performed an accurate census of the number of galaxies in the Universe. The group came to the surprising conclusion that there are at least 10 times as many galaxies in the observable Universe as previously thought. The results have clear implications for our understanding of galaxy formation, and also help solve an ancient astronomical paradox – why is the sky dark at night?
Fri, 07 Oct 2016 16:48:00 UTDuring the last month of Rosetta's operations at Comet 67P/Churyumov-Gerasimenko, it was no longer possible to observe the comet with telescopes on Earth because it was too close to the Sun's position in the sky and therefore not visible in the night-time. Fortunately, NASA's Kepler space observatory stepped in, taking images of the comet every 30 minutes from 7 to 20 September, providing important context to Rosetta's in situ measurements.
Fri, 07 Oct 2016 09:24:00 UTToday, ESA's LISA Pathfinder Science Archive opens its virtual gates to the world. It contains data collected by the satellite during the mission's first few months, covering the nominal operations phase of the LISA Technology Package (LTP) – the European payload on LISA Pathfinder.
Fri, 30 Sep 2016 10:19:00 UTESA’s historic Rosetta mission has concluded as planned, with the controlled impact onto the comet it had been investigating for more than two years.
Tue, 27 Sep 2016 12:49:00 UTOver the past two years, Rosetta has kept a close eye on many properties of Comet 67P/Churyumov-Gerasimenko, tracking how these changed along the comet's orbit. A very crucial aspect concerns how much water vapour a comet releases into space, and how the water production rate varies at different distances from the Sun. For the first time, Rosetta enabled scientists to monitor this quantity and its evolution in situ over two years.
Tue, 13 Sep 2016 13:32:00 UTThe first catalogue of more than a billion stars from ESA's Gaia satellite was published today – the largest all-sky survey of celestial objects to date.
Tue, 23 Aug 2016 09:48:00 UTProposals are solicited for observations with XMM-Newton in response to the sixteenth Announcement of Opportunity, AO-16, issued 23 August 2016. This AO covers the period May 2017 to April 2018 and is open to proposers from all over the world.
