Astronomers used a method once theorized by Albert Einstein to find a mysterious and rare planet on the edge of our galaxy. The planet, AT2021uey b, is a Jupiter-sized gas giant located about 3,200 ...

Using gravitational microlensing, scientists have discovered a rare, large planet at the edge of the Milky Way. The planet is only the third to be found on the outskirts of our galaxy's dense central ...

We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the Galactic bulge/bar, an assignation that can be confirmed by two epochs of ...

Gravitational microlensing is a transient but powerful phenomenon that occurs when a foreground mass – such as a star or a planetary system – temporarily magnifies the light from a more distant ...

Most of the exoplanets we’ve discovered have been in relatively tight orbits around their host stars, allowing us to track them as they repeatedly loop around them. But we’ve also discovered a handful ...

In context: NASA estimates that a single galaxy may harbor trillions of rogue planets. These starless worlds drift alone through interstellar space and have no parent star. They remain challenging to ...

Scientists have discovered a rogue planet roaming the Milky Way after combining observations from Earth and a space telescope. This rare dual perspective allowed them to weigh the planet and pinpoint ...

Astronomers have found a new exoplanet that could alter the standing theory of planet formation. With a mass that’s between that of Neptune and Saturn, and its location beyond the “snow line” of its ...
