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

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 ...

Using the Keck Planet Imager and Characterizer (KPIC), astronomers have performed high-resolution spectroscopic observations ...

By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new ...

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

Using data from the European Space Agency’s Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is ...

NASA artist’s conception of a brown dwarf (main) and stock image of the planets in the solar system (inset). An object between 2 and 50 times the mass of Jupiter may have flown through our ...

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

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 ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course.

Brown dwarfs (BDs) are intermediate objects between planets and stars, occupying the mass range between 13 and 80 Jupiter masses (0.012 and 0.076 solar masses). Although many brown dwarfs have ...
