Scientists using data from the European Space Agency’s Gaia mission have made a groundbreaking discovery: a massive exoplanet ...

Since its launch in 2013, Gaia has been dedicated to creating an accurate three-dimensional map of the Milky Way. Using two high-precision optical telescopes, the spacecraft carefully records the ...

The ESA’s Gaia mission mapped the positions and velocities of stars with extreme precision by measuring about one billion ...

Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to ...

"With an orbital period of 570 days, it is a relatively cold gas giant planet," said Guðmundur Stefánsson of the University ...

With an assist from the NEID spectrograph, a team of astronomers have confirmed the existence of exoplanet Gaia-4b—one of the ...

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.

Using in part the NEID spectrograph mounted on the WIYN 3.5-meter Telescope at the U.S. National Science Foundation Kitt Peak ...

The European satellite, launched in 2013, has exhausted its gas reserves and is preparing to return to a stable orbit before being 'passivated.' But while the data collection that revolutionized ...

Because Gaia precisely tracked the motion of stars – a technique known as astrometry – thousands of new objects are expected to be discovered in its data. A planet in orbit around a star ...
