Gaia

Gaia is a space observatory launched by the European Space Agency in 2013. It is expected to remain operational until 2024 or more. The spacecraft can measure the position, distances and motions of stars with high precision. Its aim is to construct the largest and most precise 3D space catalog, having around 1 billion astronomical objects like stars, planets, comets, asteroids, quasars and others.
The spacecraft monitored each of its target objects around 70 times over the first five years of the mission to precisely calculate the position and motion of each target. It is expected to detect thousands of Jupiter-sized exoplanets beyond the Solar System.
