Earth-like exoplanets might be more common throughout the Milky Way than previously believed, astronomers report in a new study.

Located in the constellation Sagittarius, it was detected through its effect on the light of a distant star, a phenomenon known as gravitational microlensing. Initially, another team had suggested the ...

By studying light anomalies caused by gravitational microlensing, the team detected one such super-Earth, OGLE-2016-BLG-0007, which has a mass roughly twice that of Earth and an orbit wider than ...

“Finding a microlensing star with a planet is hard-squared. We have to look at hundreds of millions of stars to find even a hundred of these things.” For the study, the researchers used the ...

A new study released on Thursday describes a search for what are called "microlensing" events, where a planet acts as a gravitational lens that magnifies the star it's orbiting, causing it to ...

A lonely black hole roaming the cosmos in solitude has been confirmed for the first time. A closer look has revealed the dark ...

The discovery came after a small extrasolar planet, or "exoplanet," in a wide orbit around its star was discovered, courtesy of a gravitational "microlensing" event designated OGLE-2016-BLG-0007.
