An international research team has made an unexpected discovery with the ‘Euclid’ spacecraft: in a nearby galaxy they found a so-called Einstein ring, an extremely rare phenomenon.
“The Galaxy NGC 6505 has been known for a long time. And yet this ring has never been observed before, “said Esa-Euclid scientist Valeria Pettorino. The Einstein ring was accidentally discovered in a test photo that was actually not intended for scientific purposes. When the scientists precisely analyzed the photos, they recognized the typical ring -shaped structure.
An Einstein ring is an extremely rare astronomical phenomenon of the European Space Agency (ESA). The ring -shaped glow comes from a galaxy that is far away. A galaxy is a stack of stars, dust and interstellar gas, which is held together by gravity. The light of the newly discovered Einstein ring comes from a galaxy that is 4.42 billion light years away from the earth. She was never known before and therefore has no name.
Einstein predicted phenomenon
The Galaxy NGC 6505, which can be seen the ring, is located between the nameless galaxy and the earth. The gravity of the Melkweg is so strong that it bends the room around her. The light of the background system can therefore no longer fly straight out, but is bent around the Milky Way. This results in a circular light ring around the Milky Way. The rare phenomenon of Albert Einstein in his general theory of relativity has predicted.
According to the ESA, investigating the rings should help to learn something about the expansion of the universe and to know the effects of invisible dark matter and dark energy. The largest and most accurate 3D card in the universe must be made in the coming years.
