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

"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 ...

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 ...

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 ...

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

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

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

Scientists also discovered a second planet, a brown dwarf orbiting another low-mass star. Gaia-5b orbits the Gaia-5 star, around 134 light-years away from Earth.

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

ESA’s decade-long Milky Way Gaia mapping mission still has tons of data to release over the next few years. Expect surprises.

Scientists have found two unusual objects in deep space. One is so big it could fit 21 Jupiters inside but is neither a star nor a planet.
