Microlensing is the only known method capable of discovering planets at truly great distances from Earth. Whereas radial velocity searches look for planets in our immediate galactic neighborhood, up ...

David Bennett, a University of Notre Dame astrophysicist, is a member of an international team of astronomers that has discovered a potentially rocky, icy body that may be the smallest and coolest ...

One of the closest galaxies to the Milky Way almost got away with theft. However, new simulations convicted the Large Magellanic Cloud (LMC) of stealing stars from its neighbor, the Small Magellanic ...

For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting ...

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 ...

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 confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing. NASA's Hubble Space Telescope ...

What information is obtainable through gravitational lensing and how? Patrick A. CloughWichita, Kansas Gravitational lensing is the effect by which comparatively nearby objects, such as clusters of ...

Artist’s concept of how WFIRST will use microlensing – the bending and focusing of starlight via the gravity of distant objects – to search for exoplanets. WFIRST will focus on the region near the ...
