Gaia is a space observatory of the European Space Agency (ESA) that was launched in 2013 and is planned to operate until March 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, [5] [6] and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color.

Gaia Sky is an open-source astronomy visualisation desktop and VR program with versions for Windows, Linux and macOS.It is created and developed by Toni Sagristà Sellés in the framework of ESA's Gaia mission to create a billion-star multi-dimensional map of our Milky Way Galaxy, in the Gaia group of the Astronomisches Rechen-Institut (ZAH, Universität Heidelberg).
The first launch to use the complex occurred on 21 October 2011, when a Soyuz ST-B launched the first two Galileo In Orbit Validation spacecraft. [2]The site's equatorial latitude allows a greater payload mass to be delivered into geosynchronous transfer orbit compared to existing Soyuz launch facilities at the Baikonur Cosmodrome in Kazakhstan.
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 ...
English: An all-sky view of stars in the Milky Way and neighbouring galaxies, based on the first year of observations from ESA’s Gaia satellite, from July 2014 to September 2015. This map shows the density of stars observed by Gaia in each portion of the sky.

ESA's Gaia mission also uses a Lissajous orbit at Sun–Earth L2. [10] In 2011, NASA transferred two of its THEMIS spacecraft from Earth orbit to Lunar orbit by way of Earth–Moon L1 and L2 Lissajous orbits. [11] In June 2018, Queqiao, the relay satellite for China's Chang'e 4 lunar lander mission, entered orbit around Earth-Moon L2. [12] [a]
Swarm is a European Space Agency (ESA) mission to study the Earth's magnetic field.High-precision and high-resolution measurements of the strength, direction and variations of the Earth's magnetic field, complemented by precise navigation, accelerometer and electric field measurements, will provide data for modelling the geomagnetic field and its interaction with other physical aspects of the ...
