The Guardian reports that the Euclid Space Telescope has captured a rare phenomenon called an Einstein ring.
This shows how strong the curvature of spacetime is due to the gravitational pull of a galaxy.
The image shows the nearby galaxy NGC 6505, which appears to be surrounded by a halo. This is the light from behind another galaxy, bent by the galaxy's gravitational pull and creating a bright ring.
"This is a wonderful, extraordinary, stunning, and successful discovery. Such perfect 'Einstein rings' are scarce," astronomer Professor Stephen Serjeant said.
Einstein's rings allow astronomers to see objects that would otherwise be invisible.
