An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to...

Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September. Members of the media are invited to join Rosetta science and mission control experts at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany, on 29 and 30 September, to follow the conclusion of this historic mission.

A fossilised remnant of the early Milky Way harbouring stars of hugely different ages has been revealed by an international team of astronomers. This stellar system resembles a globular cluster, but is like no other cluster known.

Media representatives are invited to a briefing on the first data release of ESA's Gaia mission, an astrometry mission to map the stars of our galaxy, the Milky Way. The media briefing is being organised at ESAC, in Spain, on Wednesday 14 September 2016, 11:30-13:00 CEST.

ESA's Planck satellite has revealed that the first stars in the Universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed to account for reionising atoms in the cosmos, having completed half of this process when the Universe...

A giant bubble surrounding the centre of the Milky Way shows that six million years ago our Galaxy's supermassive black hole was ablaze with furious energy. It also shines a light on the hiding place of the Galaxy's so-called 'missing' matter.

In unprecedented observations made earlier this year, Rosetta unexpectedly captured a dramatic comet outburst that may have been triggered by a landslide.

Since its launch in December 2013 Gaia has been sweeping the skies mapping around one billion stars. The data collected will allow astronomers to probe the very nature of the astronomical objects observed by the spacecraft. But before the data can be useful to the scientific community they must pass through a complex and robust processing...

Operating in the depths of space, far beyond the Moon's orbit, ESA's Gaia spacecraft has now completed two years of a planned five-year survey of the sky. Despite a series of unexpected technical challenges, the mission is on track to complete the most detailed and complex mapping of the heavens ever undertaken.
