description Gaia Overview

The Gaia observatory is a space-based mission operated by the European Space Agency. It meticulously surveys our galaxy, the Milky Way, producing an unprecedented three-dimensional map through astrometry. This data allows astronomers to determine the positions and motions of over one billion stars with exceptional accuracy. The information is crucial for understanding galactic structure, stellar evolution, and the formation of planetary systems.

It benefits researchers studying fundamental astrophysics and cosmology.

help Gaia FAQ

When was the Gaia spacecraft launched?

Gaia was launched by the European Space Agency on December 19, 2013, aboard a Soyuz rocket from the Guiana Space Centre in Kourou, French Guiana. It began its scientific survey in July 2014 and continues to operate as of the mid-2020s.

Where is Gaia positioned in space?

Gaia operates from the second Sun-Earth Lagrange point (L2), approximately 1.5 million kilometers from Earth in the direction away from the Sun. This gravitationally stable location allows the spacecraft to maintain a consistent thermal environment and conduct uninterrupted sky surveys while continuously spinning.

How many stars has Gaia cataloged so far?

As of its third data release (DR3) in June 2022, Gaia has measured the positions, distances, and motions of approximately 1.8 billion stars. This represents the most extensive stellar catalog ever produced, covering sources down to roughly magnitude 21.

What was included in Gaia's DR3 data release?

Gaia DR3 provided radial velocity measurements for over 30 million stars, astrophysical parameters for hundreds of millions of sources, and data on exoplanets, solar system asteroids, and over a million distant quasars. Astronomers worldwide use this data for research ranging from Milky Way formation history to tests of dark matter theories.
