Meanwhile, gravitational microlensing (usually just called microlensing) involves searching for increases in brightness in deep space. These brilliant flashes are from a planet and its star ...

Astronomers have used the technique of gravitational microlensing to measure how common planets are in the Milky Way. After a six-year search that surveyed millions of stars, the team concludes ...

Researchers from NASA’s Goddard Space Flight Center and Osaka University in Japan have used the phenomenon of gravitational microlensing to estimate the number of rogue planets that could be ...

This revelation comes from a method known as gravitational microlensing. It’s a rare cosmic event that happens when a star, or sometimes even a planet, drifts into perfect alignment between ...

First, because microlensing is purely a gravitational effect, it is independent of the mass–luminosity–metallicity relation, cooling curve, or atmospheric properties. Second, as the light from ...

Gravitational microlensing uses a much smaller object as a lens, like a single star or galaxy. From our perspective here on Earth, when a "nearby" star passes in front of a more distant one ...

Using the gravitational microlensing method that is highly sensitive to planets that lie in a habitable zone around the host stars, astronomers, including members from the Niels Bohr Institute, have ...

Using data from a gravitational microlensing event, astronomers have identified a small planet orbiting its star at a distance similar to Saturn’s, challenging the assumption that super-Earths ...

Einstein first predicted gravitational microlensing in his theory of general relativity. It works kind of like how it sounds: it’s gravity acting like a lens that can manipulate light.

This microlensing event was detected in 2018 by the Optical Gravitational Lensing Experiment (OGLE) using a telescope in Chile, and the Korea Microlensing Telescope Network (KMTNet). Analyzing the ...
