Thought this might as well have a thread.

Gaia Early Data Release 3: Summary of the contents and survey properties

Gaia Sky 3.0.0 has been released, as well.

(I can't seem to run the new version of Gaia Sky; it becomes unresponsive after running for a minute or less.)

A year and a half later, the final Gaia Data Release 3 is out.

Gaia exoplanet results:

Gaia's first confirmed exoplanets were published almost a month ago. Gaia-1b and Gaia-2b are both transiting hot Jupiters. They're included in the DR3 data along with 39 other transit candidates and numerous previously known transiting exoplanets.

This new paper describes exoplanets (as well as brown dwarfs and multiple stars) detected by Gaia astrometry. Notable results (previous astrometric detections linked):

• The confirmed planets detected by astrometry are HD 175167 b, HD 132406 b, Iota Horologii b, BD-17 63 b, HD 111232 b, HD 81040 b, HD 142 b, and Gliese 876 b.
• With a true mass of 14.3 Jupiter masses, HD 164604 b is at the borderline between planets and brown dwarfs.
• Among the brown dwarfs detected by astrometry, BD-00 4475 b is currently included in the NASA Exoplanet Archive because its minimum mass is below 30 Jupiter masses. Its true mass is found to be 48.4 Jupiter masses.
• The planetary candidates HD 114762 b, HD 162020 b, and KIC 7917485 b (Kepler-1648b) are confirmed to be stellar-mass.
• Many new candidate planets are detected by astrometry. These include candidates orbiting HIP 66074 (GJ 9452), HIP 28193 (HD 40503), HD 12800 (54 Cassiopeiae), HD 3221, and the nearby white dwarf WD 0141-675 (GJ 3112).
