Astronomers have finally weighed a wandering “rogue” planet, uncovering a Saturn-mass world flung into the galaxy after a ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

In doing so, they found this orphan is within the same weight class as Saturn, strengthening the case that the galaxy teems ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift ...

Two separate research teams have observed a previously unseen microlensing event, confirming the existence of a particular ...

A Saturn-mass planet, which had been drifting alone through space after escaping the gravitational pull of its star, has been captured by a Korean ...

Astronomers just measured the mass of a free-floating planet without a star for the first time ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Since 1995 scientists have found more than 5,000 exoplanets ...

NASA’s Hubble Space Telescope and the W. M. Keck Observatory in Hawaii have made independent confirmations of an exoplanet orbiting far from its central star. The planet was discovered through a ...

Astronomers have, for the first time, found a planet orbiting a binary star system using microlensing. Gravitational lensing is a technique that made its name by aiding in the discovery of galaxies.

Astrophysicists have discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing -- an astronomical phenomenon and the only known method capable of ...
