A recently released image taken by the Hubble Space Telescope shows a distant galaxy that has been warped and distorted by a phenomenon called gravitational lensing. This phenomenon allows scientists ...

When a gravitational lens magnifies a background galaxy, why don't we see the object doing the lensing, as we would if looking through an optical lens? Robert Hertrick Pittsburgh Gravitational lensing ...

The European Space Agency has released the first major batch of data from its “dark universe” telescope Euclid. What’s inside could change our understanding of dark matter and the expansion of the ...

The key to weird-looking and repeating galaxies is a phenomenon first predicted by Albert Einstein over 100 years ago. When you purchase through links on our site, we may earn an affiliate commission.

Clumps and clusters of galaxies exhibit gravitational effects on the light-and-matter behind them due to the effects of weak gravitational lensing. In addition, arcs, multiple images of the same ...

Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. If Einstein's ...

From a serendipitous discovery made with LBT, a team of astronomers led by Arjen van der Wel from the Max Planck Institute for Astronomy (MPIA) has found the most distant gravitational lens yet — a ...
