The Gaia mission continues to create a precise three-dimensional map of astronomical objects throughout the Milky Way and map their motions, which encode the origin and subsequent evolution of the Milky Way.
Gaia BH1 (Gaia DR3 4373465352415301632) is a binary system consisting of a G-type main-sequence star and a likely stellar-mass black hole, located about 1,560 light-years (478 pc) away from the Solar System in the constellation of Ophiuchus.
Gaia BH3 (Gaia DR3 4318465066420528000) is a binary system consisting of a metal-poor giant star with spectral type G and a stellar-mass black hole. Gaia BH3 is located 1926 light years away (590.6 ± 5.8 pc away) in the constellation of Aquila. Gaia BH3 is the first black hole discovered from preliminary Gaia DR4 astrometric data.
Gaia has been mapping the Milky Way ever since, and now the ESA has released a 3D map featuring over a billion stars -- we've never seen 400 million of those before -- based on the data it ...
Map of stars cataloged by the Gaia release in 2021, displayed as density mesh in the diagram. The ESA spacecraft Gaia provides distance estimates by determining the parallax of a billion stars and is mapping the Milky Way with four planned releases of maps in 2016, 2018, 2021 and 2024. Data from Gaia has
The Sun is a G-type main-sequence star that makes up about 99.86% of the mass of the Solar System. It has an absolute magnitude of +4.83, estimated to be brighter than about 85% of the stars in the Milky Way, most of which are red dwarfs. [32] [33] The Sun is a Population I, or heavy-element-rich, [b] star. [34]

Map of stars within 100 parsecs of the Sun, the Hyades is at 180° galactic longitude. Astrometry [ edit ] A 2018 Gaia DR1 study of the Hyades Cluster determined a (U, V, W) group velocity of (−41.92 ± 0.16, −19.35 ± 0.13, −1.11 ± 0.11) km/sec, based on the space velocities of the 138 core stars.
