When gravity—an invisible yet ubiquitous force—bends and distorts light from distant galaxies, Earthbound observers get a ...

A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter ...

Astronomers have made a discovery that looks like something out of science fiction: a rare “Einstein Cross” with an extra ...

A team of international astronomers have identified a cosmic oddity unlike anything seen before: a galaxy bent by gravity into an Einstein Cross with not four but five distinct images.

How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

For scientists, that has long posed a problem: According to physicists’ best current theories, matter and its counterpart, ...

How does one time the velocity of a black hole racing across the universe? A billion-year-old impact, painstakingly sensitive detectors, and ten years of gravitational wave science were needed in this ...

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a ...

The reason that teams on multiple telescopes in all different directions could hear this noise is that this annoying sound was actually the Cosmic Microwave Background (CMB)—radiation left over from ...
