Most of the planets we’ve identified are in orbit around stars and formed from the disks of gas and dust that surrounded the ...

An international team of scientists led by Sasha Hinkley at the University of Exeter have used the European Space Agency’s Gaia telescope to detect a new exoplanet, a planet orbiting a star other than ...

Gaia data reveals signs of planets forming around young stars by measuring stellar motion, identifying planetary, brown dwarf, and stellar companions in early star systems ...

For the first time, astronomers have directly measured the mass of a rogue planet, a celestial body wandering through space ...

A lonely world the size of Saturn is drifting through the Milky Way with no star to warm it, and for the first time ...

Gaia was built to map stars, not find planets. Yet, its precise tracking of stellar wobbles just led to the discovery of a giant exoplanet and a mysterious brown dwarf. Planets tug on their stars, ...

The NEID spectrograph on the WIYN 3.5-meter Telescope conducted crucial follow-up observations to confirm one of the most massive planets known to orbit a low-mass star One mission that NEID is ...

The mass of a very young exoplanet has been revealed for the first time using data from ESA’s star mapping spacecraft Gaia and its predecessor, the quarter-century retired Hipparcos satellite.

Astronomers have spotted something unusual, a planet that doesn’t orbit any star. It’s just drifting alone through space.

Direct images of HIP 99770 b. We show the two highest-quality data sets, using SCExAO/CHARIS observations on (A) 19 May 2021 and (B) 17 October 2021. Data were processed using the adaptive, locally ...
