Sneak peek of Gaia’s sky in colour 16 August 2017 While surveying the positions of over a billion stars, ESA’s Gaia mission is also measuring their colour, a key diagnostic to study the physical properties of stars. A new image provides a preview of Gaia’s first full-colour all-sky map, which will be unleashed in its highest resolution with the next data release in 2018. Read more

Artificial brain helps Gaia catch speeding stars 26 June 2017 With the help of software that mimics a human brain, ESA’s Gaia satellite spotted six stars zipping at high speed from the centre of our Galaxy to its outskirts. This could provide key information about some of the most obscure regions of the Milky Way. Read more

The future of the Orion constellation 09 June 2017 A new video, based on measurements by ESA’s Gaia and Hipparcos satellites, shows how our view of the Orion constellation will evolve over the next 450 000 years. Read more

Gaia’s snapshot of another galaxy 20 April 2017 While compiling an unprecedented census of one billion stars in our Galaxy, ESA’s Gaia mission is also surveying stars beyond our Milky Way. A new image of M33, also known as the Triangulum galaxy, shows tens of thousands of stars detected by Gaia, including a small stellar census in its star-forming region NGC 604. This is a striking example of the mission’s potential to detect and characterise stars in nearby galaxies. Read more

Two million stars on the move 12 April 2017 The changing face of our Galaxy is revealed in a new video from ESA’s Gaia mission. The motion of two million stars is traced 5 million years into the future using data from the Tycho-Gaia Astrometric Solution, one of the products of the first Gaia data release. This provides a preview of the stellar motions that will be revealed in Gaia’s future data releases, which will enable scientists to investigate the formation history of our Galaxy. Read more
