The Einstein ring was hidden in the galaxy NGC 6505, as the European Space Agency (ESA) announced on Monday. This galaxy is "only" 590 million light years away from Earth - a small distance on a cosmic scale.
"The galaxy has been known to astronomers for a very long time. And yet this ring has never been observed before," said ESA scientist Valeria Pettorino.
The Einstein ring was discovered by chance in a test image that was not actually intended for scientific purposes. According to the ESA, such a ring is an extremely rare astronomical phenomenon. Researchers from the Swiss Federal Institute of Technology in Lausanne were involved in the data analysis.
The researchers reported on the discovery in the journal "Astronomy & Astrophysics".
