Gaia mission news
Explore the stars in our galactic neighbour, the Large Magellanic Cloud, as viewed by ESA’s Gaia satellite
The movements of more than 300 000 stars surveyed by ESA’s Gaia satellite reveal that rare close encounters with our Sun might disturb the cloud of comets at the far reaches of our Solar System, sending some towards Earth in the distant future.
A preview of Gaia’s sky in colour provides a taste of the full-colour map of more than a billion stars that will be released next year
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.
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.
Media briefing replay: Gaia scientists present stellar catalogues obtained during the first year of ESA’s star surveyor
ESA’s Gaia mission has published its first catalogue of a billion stars
The 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.

Gaia’s first star catalogue will be unveiled on Wednesday, 14 September. Watch livestream from 09:30 GMT / 11:30 CEST
Livestreaming of the media briefing on the first data release from ESA’s Gaia mission will begin on 14 September at 09:30 GMT (11:30 CEST).
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.
A local cosmic celebrity was recently pictured among the multitude of stars and Solar System bodies surveyed by ESA’s Gaia satellite: Comet 67P/Churyumov–Gerasimenko, currently accompanied by another ESA spacecraft, Rosetta.
Last Friday, 21 August, ESA’s billion-star surveyor, Gaia, completed its first year of science observations in its main survey mode.
This image, based on housekeeping data from ESA’s Gaia satellite, is no ordinary depiction of the heavens. While the image portrays the outline of our Galaxy, the Milky Way, and of its neighbouring Magellanic Clouds, it was obtained in a rather unusual way.
While scanning the sky to measure the positions and movements of stars in our Galaxy, Gaia has discovered its first stellar explosion in another galaxy far, far away.
Following extensive in-orbit commissioning and several unexpected challenges, ESA’s billion-star surveyor, Gaia, is now ready to begin its science mission.
ESA’s billion-star surveyor Gaia is slowly being brought into focus. This test image shows a dense cluster of stars in the Large Magellanic Cloud, a satellite galaxy of our Milky Way.
With a final, modest, thruster burn yesterday afternoon, ESA’s billion-star surveyor finalised its entry into orbit around ‘L2’, a virtual point far out in space. But how do you orbit nothing? And who can show you how to get there, anyway?
