The abundance of low-mass compact objects, at or below the hydrogen-burning mass limit of 0.08M ⊙ (where M ⊙ is the solar mass), remains an open question. This abundance has implications for such ...

In a new blind survey of gravitational microlensing, an international team of astronomers has detected likely evidence for four Earth-sized planets wandering freely through interstellar space. Using ...

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.

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 ...

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 ...
