Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results show that dark matter interacts with itself even less than previously thought.

ESA's Rosetta spacecraft has made the first measurement of molecular nitrogen at a comet, providing clues about the temperature environment in which Comet 67P/Churyumov-Gerasimenko formed.

The first set of images from Rosetta's NAVCAM has been made available to all users via ESA’s Planetary Science Archive (PSA). This first batch of image data covers the period leading up to 2 July 2014, prior to Rosetta's arrival at comet 67P/C-G.

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, spotted four images of a distant exploding star. The images are arranged in a cross-shaped pattern by the powerful gravity of a foreground galaxy embedded in a massive cluster of galaxies.

It may have been designed to probe and monitor the Sun, but the ESA/NASA Solar and Heliospheric Observatory (SOHO) has also found fame as a comet finder. A record-breaking 2890 comets have been discovered with SOHO since its launch in 1995, more than any other comet hunter in history!

Through this Announcement of Opportunity (AO) ESA solicits the participation of the scientific community in the role of Interdisciplinary Scientists (IDSs) in the JUICE mission. Proposals are due by 15 April 2015 at 12:00 CEST (noon) and shall be preceded by a mandatory Letter of Intent due by 20 March 2015.

Astronomers have discovered that the winds from supermassive black holes at the centre of galaxies are blasted out in all directions. This new finding was made possible by observations with ESA's XMM-Newton and NASA's NuSTAR X-ray telescopes and it supports the picture of black holes having a significant impact on star formation of their host...

These new NASA/ESA Hubble Space Telescope images capture a rare occurrence as three of Jupiter's largest moons parade across the giant gas planet's banded face. Hubble took a string of images of the event which show the three satellites - Europa, Callisto and Io - in action.

New maps from ESA's Planck satellite uncover the 'polarised' light from the early Universe across the entire sky, revealing that the first stars formed much later than previously thought.

ESA's Rosetta probe is preparing to make a close encounter with its comet on 14 February, passing just 6 km from the surface.

Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.

The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714. This galaxy has drifted too close to another nearby galaxy and the dramatic interaction has twisted its spiral arms out of shape, dragged streams of material out into space, and triggered bright bursts of star formation.

ESA's Rosetta mission is providing unique insight into the life cycle of a comet's dusty surface, watching 67P/Churyumov-Gerasimenko as it sheds the dusty coat it has accumulated over the past four years.
