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

Located in the constellation Sagittarius, it was detected through its effect on the light of a distant star, a phenomenon known as gravitational microlensing. Initially, another team had suggested the ...

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 ...

The Hubble Space Telescope has been used to determine the mass of white dwarf star LAWD 37. It is "56 percent the mass of our Sun," according to NASA/ESA. Credit: NASA, ESA, P. McGill (Univ.

It used data from the Korea Microlensing Telescope Network (KMTNet), a global system of telescopes based in South Africa, Chile, and Australia. Using a technique called gravitational microlensing ...

A new device uses quantum optics to filter out starlight in real time — bringing scientists closer to directly observing ...

The findings rely on gravitational microlensing, where a massive object between Earth and a distant star bends light. This temporary light boost allows researchers to detect planets otherwise too ...

"However, the difficulty of exoplanet discovery warrants cross-validation with a multiplicity of observational techniques such as transits, velocimetry, and gravitational microlensing. Therefore ...

Gravitational microlensing in the wave-optics (WO) regime occurs when the Schwarzschild radius of a lensing object is comparable to or smaller than the wavelength of incoming gravitational waves (GWs) ...

Abstract: A new algorithm for the autonomous fitting of light curves of gravitational microlensing by binary lenses is presented here. The algorithm relies on the combination of artificial neural ...

Data collected by the Microlensing Observations in Astrophysics survey helped ... the star's exact speed and determine whether it is sufficient to escape our galaxy's gravitational pull. This ...
