The "dark universe detective" space telescope Euclid has discovered its first Einstein ring in the process, learning about dark matter at the heart of a distant galaxy.

Euclid space telescope has photographed an incredible astronomical phenomenon called an 'Einstein ring.' The image shows a striking Einstein ring surrounding the galaxy NGC 6505, situated 590 million light-years away.

Euclid space telescope has discovered an extremely rare Einstein ring. Einstein rings of light are produced when two galaxies are almost perfectly aligned, with one behind the other from a fixed perspective.

Scientists spot giant ‘Einstein ring’ nearby in space – by accident - Discovery came as astronomers were checking that new space telescope is working properly

This ring is made up of light from a galaxy 4.42 billion light years away and what can be seen from Earth is distorted by gravity. The distant galaxy has not been observed before
