Euclid, a space telescope on a mission to uncover the secrets of dark matter and dark energy, has already made a stunning discovery: a perfectly formed Einstein ring hidden in a well-known galaxy.

Einstein rings help scientists study dark matter and cosmic expansion. Euclid will find thousands more lenses to map the ...

Gravitational lensing occurs when the gravity of a massive object, like a galaxy, warps the fabric of spacetime, bending the light from a more distant background object.
