An international team of astronomer’s dark matter halo discovery an unusual astronomical Einstein Cross phenomenon: a galaxy ...

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

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.

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 ...

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 Belgian priest came up with the Big Bang almost a century ago—but he also wanted to keep science and faith as separate as ...

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

For more than two decades, astronomers have wrestled with one of the biggest mysteries in science: what is driving the ...
