Super-Earths might be far more common in the Universe than previously thought. A recent study using the KMTNet telescope network has revealed their presence in unexpected locations. This ...

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

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 ...

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

A new publication introduces the rapidly growing field of multi-messenger gravitational lensing, which combines ...

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 ...

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 ...

Most stellar-sized black holes aren't, but astronomers have been searching for them through gravitational microlensing events, where the black hole brightens and distorts light from stars toward ...

Microlensing events involving solar-mass objects typically last several weeks, whereas those that feature black holes 100 more massive than the Sun would last a few years. Previous gravitational ...

From 2006 to 2014, Japanese and New Zealand scientists teamed up to perform the Microlensing Observations in Astrophysics (MOA) II Gravitational Microlensing Survey. The survey was aimed at the ...

Using a technique called gravitational microlensing, citizen scientists will look at how the brightness of light from various stars changes over time, looking for indications that a black hole ...
