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

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

Data from the Gaia spacecraft shows that even unassuming stars can host monumental companions like massive planets.

The system is believed to be traveling at least 1.2 million miles per hour (1.93 million kilometers per hour), according to a ...

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 ...

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

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a ...

Gaia-4b is considered a super-Jupiter planet, a relatively cold gas giant, orbiting its star over 570 Earth-days. That star ...

New research from the SAGA Survey, comparing the Milky Way with 101 similar galaxies, unveils how our galaxy differs ...

A research team may have discovered a star with an exoplanet that is so fast that both will leave the Milky Way.

By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new giant "planet," plus a new brown dwarf.
