To understand gravitational lensing and dark matter, James Jee, a professor at Yonsei University, says to think of a pond ...

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Gravitational lensing occurs when things with mass create ripples and dents in the fabric of spacetime, and light has to follow along those lines, which sometimes create a magnifying glass effect ...

Gravitational lensing is a powerful tool for telescopes such as the James Webb Space Telescope as it images some of the most distant and faint early galaxies.

As the name suggests, gravitational lensing can magnify very distant objects, including some that are too far away to be seen otherwise. That gives astronomers an incredible peek into the farthest ...

A new paper claims astronomers discovered an ultramassive black hole heavier than any other black hole we've ever measured.

The gravitational lens created by the galaxy in the foreground creates four images of the active galaxy, each with a bright galactic core and two large jets of material extending from it.

The solar gravitational lens could build a decent map of any exoplanet sitting within roughly 100 light years of us. Compare that to any telescope past and future, and there's simply no competition.

The new work involves a third way to measure the distance that's independent of the other two. It relies on gravitational lensing, where the distortion in space-time caused by a massive object ...

Rubin Observatory’s LSST will help scientists study the gravitational lensing they’ve already seen, but it will also help them greatly increase their catalogue of examples. Scientists know of about ...

“SN Zwicky is the smallest resolved gravitational lens system found with optical telescopes. iPTF16geu was a wider system but had larger magnification,”says Goobar.

The gravitational lensing correction tool developed in this study is already being used in observational studies today, and Naokawa and Namikawa will continue to use it to analyze data for future ...
