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 ...

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 ...

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

The Gaia mission, launched by the European Space Agency, has completed a decade of groundbreaking astronomical observations, collecting over three trillion data points on two billion stars and ...

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

The Gaia telescope aimed to create an accurate and detailed 3D map of billions of stars in our galaxy. Its findings have flipped astronomers' understanding of the Milky Way on its head and have led to ...

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.

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 ...
