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 ...

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.

To Hannaleigh Scott, it looked like someone had spilled salt all over a dark tablecloth - just the way any starry night might appear to a casual observer. But this was no ordinary star census. And one ...

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 ...

In exoplanet hunting today, there seems to be one burning question that nearly every new article published asks: Where did these planets come from? Subscribe to read this story ad-free Get unlimited ...

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 ...

A new statistical study of planets found by a technique called gravitational microlensing suggests that Neptune-mass worlds are likely the most common type of planet to form in the icy outer realms of ...
