ESA Science & Technology - Cosmic scales covered by Gaia's second data release

The second data release from ESA's Gaia mission contains a high-precision catalogue of the entire sky, covering celestial objects near and far. It includes objects such as asteroids in our Solar System as well as the stellar population of our Milky Way Galaxy and its satellites – globular clusters and nearby galaxies. It also extends to distant quasars that are being used to define a new celestial reference system.

This infographic summarises the cosmic scales covered by this comprehensive dataset, which provides a wide range of topics for the astronomy community.
