Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and operated until March 2025 (planned). The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [6] [7] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.

The limits of observation as visualized by the Milky Way's star density map. Source: Gaia spacecraft's 2021 data release. Many projects have attempted to bridge the gap in knowledge caused by the Zone of Avoidance. The dust and gas in the Milky Way cause extinction at optical wavelengths, and foreground stars can be confused with background ...
The Gaia catalogues are star catalogues created using the results obtained by Gaia space telescope. The catalogues are released in stages that will contain increasing amounts of information; the early releases also miss some stars, especially fainter stars located in dense star fields. [1] Data from every data release can be accessed at the ...

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. [4]
The Gaia Data Processing and Analysis Consortium (DPAC) is a group of over 400 European scientists and software engineers formed with the objective to design, develop and execute the data processing system for ESA's ambitious Gaia space astrometry mission. It was formally formed in June 2006 by European scientists, with the initial goal of ...
Mission consists of two spacecraft, which were the first spacecraft to reach Earth–Moon Lagrangian points. Both moved through Earth–Moon Lagrangian points, and are now in lunar orbit.

Gaia is a space observatory of the European Space Agency (ESA) designed for astrometry. [ 51 ] [ 52 ] The mission aims to construct the largest and most precise 3D space catalog ever made and totaling approximately 1 billion astronomical objects , mainly stars but also planets, comets, asteroids and quasars among others.
