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

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.

High-resolution spectroscopic observations have offered a deeper understanding of HD 206893 B, a brown dwarf orbiting the star HD 206893. The Keck Planet Imager and Characterizer (KPIC) was used by ...

This week, NASA released the first image from the Europa Clipper spacecraft's voyage. The image is a mosaic of a star field, created from three shots the solar-powered orbiter captured in December of ...

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.

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

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.

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s ...

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

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 ...

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 ...
