The European Space Agency's Euclid space telescope was going through preliminary tests in September 2023 when it captured images of an Einstein Ring in a nearby galaxy.

The Euclid Space Telescope has captured a remarkable image showing an extremely rare phenomenon: a ring of light around the center of a galaxy, known as an Einstein Ring. These structures appear in telescope images due to the distorting effects of gravity, and they allow researchers to study distant galaxies which might otherwise be insibile.
