Euclid, the European Space Agency’s dark Universe detective, has made an astonishing discovery – right in our cosmic backyard ...

Einstein’s general theory of relativity predicts that light will bend around objects in space, so that they focus the light like a giant lens, with this effect being bigger for massive galaxies.

The first known Einstein Ring — named after Albert Einstein, who predicted the bending of light through his theory of relativity — was discovered in 1987. Several have been discovered in the ...

Traditional black holes, as predicted by Albert Einstein's theory of General Relativity, contain what are known as singularities, i.e. points where the laws of physics break down. Identifying how ...

Surrounding this galaxy is a nearly perfect circle of light – a phenomenon predicted by Einstein’s theory. This ring is formed by the light from a more distant galaxy, approximately 4.42 ...

Analysis - Galaxies, planets, black holes: to most people, everything about our Universe sounds and feels enormous. But while it's true that much of what happens millions of light years away is large, ...
