Inside Gaia's billion-pixel camera
ESA's Gaia mission will produce an unprecedented 3D map of our Galaxy by mapping, with exquisite precision, the position and motion of a billion stars. The key to this is the billion-pixel camera at the heart of its dual telescope. This animation illustrates how the camera works.

The great advances in any science tend to come in sudden leaps. April 25th of 2018 marks the beginning of just such a leap for much of astronomy. In the early hours of the morning, the Gaia mission’s second data release dropped. Our understanding of our own galaxy will never be the same again.

Gaia data release 3: exploring our multi-dimensional Milky Way
Since its launch in 2013 ESA’s Gaia observatory has been mapping our galaxy from Lagrange point 2, creating the most accurate and complete multi-dimensional map of the Milky Way. By now two full sets of data have been released, the first set in 2016 and a second one in 2018. These data releases contained stellar positions, distances, motions across the sky, and colour information, among others. Now on 13 June 2022 a third and new full data set will be released. This data release will contain even more and improved information about almost 2 billion stars, Solar System objects and extragalactic sources. It also includes radial velocities for 33 million stars, a five-time increase compared to data release 2. Another novelty in this data set is the largest catalogue yet of binary stars in the...

Le satellite Gaia, mètre de la galaxie
La toute dernière version du catalogue d’étoiles de notre galaxie réalisée grâce au satellite européen Gaia, situé à 1,5 million de kilomètres de la Terre, est sur le point d’être rendue publique. Cette nouvelle version répertorie et caractérise, avec une précision sans précédent, 1,8 milliard d’étoiles ! Le traitement des données scientifiques transmises par Gaia, est confié aujourd’hui à 420 scientifiques européens et 10 scientifiques internationaux. Comment est réalisé un catalogue d’étoiles ? A quoi sert-il ? Quel rôle joue la coopération européenne dans l’établissement de ce catalogue ? Quelles questions se posent à la lumière de ces nouvelles données et quels enjeux pour l’astronomie ?

Gaia: one billion stars in 3D
Narrated by Sean Pertwee. More than a million kilometres above us in space, the Gaia satellite is busy building the most precise 3D map of one billion stars in our galaxy. The satellite’s sophisticated instruments measure the distances to stars and records their movements to an unprecedented level of accuracy. Using these data, it is possible to create a 3D movie of the positions and motions of one billion stars – 1,000 times more than ever before.

Gaia discovers a unique black hole
ESA’s Gaia mission has helped discover a new kind of black hole. The new family already has two members, and both are closer to Earth than any other black hole that we know of.
The two black holes were discovered by studying ultra-precise measurements of stellar positions and motions in Gaia’s third data release.
A strange ‘wobble’ in the movement of two stars on the sky indicated that they are orbiting a very massive object. In both cases, the objects are approximately ten times more massive than our Sun. Other explanations for these massive companions, like double-star systems, were ruled out since they do not seem to emit any light.
Gaia’s second black hole, BH2, is located 3800 light-years away from Earth. It is a binary system consisting of a red giant star and likely a black hole....

The Star at the End of Time
https://www.youtube.com/watch?v=-iWGtQ03OZM
The Gaia satellite was launched in late 2013, entirely built and operated by the European Space Agency. It’s primary goal is to map the stars of the Milky Way with a scale and precision orders of magnitude greater than ever before. Gaia’s predecessor, Hipparcos, catalogued 120 thousand stars, Gaia blows it out of the water with positions, colors and brightnesses of nearly 1.7 billion stars. Gaia can see orders of magnitude fainter and further away than previous missions. But its greatest superpower is its precise astrometry – Gaia can pin down a star’s position to the equivalent of a human hair’s width at 1000 km. That’s one-to-two thousand times smaller than the resolution of the Hubble Space Telescope.

This data release will contain even more and improved information about almost 2 billion stars, Solar System objects and extragalactic sources. It also includes radial velocities for 33 million stars, a five-time increase compared to data release 2. Another novelty in this data set is the largest catalogue yet of binary stars in the Milky Way, which is crucial to understand stellar evolution.

ESA’s Gaia mission has helped discover a new kind of black hole. The new family already has two members, and both are closer to Earth than any other black hole that we know of.
The two black holes were discovered by studying ultra-precise measurements of stellar positions and motions in Gaia’s third data release.
A strange ‘wobble’ in the movement of two stars on the sky indicated that they are orbiting a very massive object. In both cases, the objects are approximately ten times more massive than our Sun. Other explanations for these massive companions, like double-star systems, were ruled out since they do not seem to emit any light.
Gaia’s second black hole, BH2, is located 3800 light-years away from Earth. It is a binary system consisting of a red giant star and likely a black hole.
In this animation of Gaia BH2, created in Gaia Sky, the orbits are accurately sized, but the back hole diameter is not to scale.

Animation created for Gaia's data release 3 on 13 June 2022: https://www.cosmos.esa.int/web/gaia/data-release-3
Zoom-in into our local neighbourhood starting from the Milky Way artistic impression all the way to the Earth and Moon, passing through:
*Milky Way artistic impression by Stefan Payne-Wardenaar
*Density maps created by Kevin Jardine of the hot star data for the paper "Gaia Data Release 3: Mapping the asymmetric disc of the Milky Way" by the
Gaia Collaboration, Drimmel, R., et al. 2022
*Density maps created by Kevin Jardine for the paper "Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars" by the Gaia Collaboration, R.L. Smart, et. al. 2020.
*Density map created by Kevin Jardine for the 10 parsecs sample from the paper "The 10 parsec sample in the Gaia era" by C. Reylé et.al. 2021.
Combining the model with maps at three different scales allows a video
showing a fly in from the entire galaxy right to the Earth.
