Gaia, a mission designed to map stars, has accidentally become a planet hunter. Using precise astrometry, it detected stellar ...

Gaia unexpectedly discovered a giant exoplanet and a puzzling brown dwarf, challenging planetary formation theories and ...

The successes of Gaia will help inspire new generations of scientists to make a successor mission a reality and to continue to push the boundaries of space astrometry, in the spirit of Gaia's legacy.

And so, consequently, we haven’t been able to do that very well, and so it’s single digits, the number of exoplanets we know from astrometry, this, this technique. Gaia, by the time of its ...

Gaia is a space telescope onboard a satellite that has orbited the sun for 11 years. With the help of astrometry, which is a technique to measure the positions, distances and movements of stars ...

This is an artist impression of the exoplanet Gaia-4b and the brown dwarf Gaia-5b, which were both discovered by ESA’s Gaia mission. This artist impression visualises a portion of the orbital ...

Unlike the radial velocity method used by NEID, Gaia uses a technique known as astrometry to detect a star’s motion. This technique involves measuring the subtle motion of a star as it is tugged ...

Gaia-4b, a massive exoplanet, is the first confirmed using Gaia’s astrometric technique, marking a milestone in space exploration. 'A new eye on the Sun': NASA's PUNCH to track solar storms in ...
