- Recently, the Euclid space mission of the European Space Agency (ESA) spotted an Einstein ring in the galaxy NGC 6505.
- This is located just 590 million lightyears from the earth.
- An Einstein ring is a special case of strong gravitational lensing.
- Astronomers discovered the first Einstein ring in 1998, more than 80 years after Einstein predicted their existence.
- An Einstein ring is created when a gravitational lens distorts light coming from a distant background object, like a star or a galaxy.
