When a massive foreground galaxy, like NGC 6505, sits directly between us and a more distant source, its gravity acts as a lens, bending the light around it.

In the image captured by Euclid, the nearby galaxy NGC 6505—located approximately 590 million light-years from Earth—is surrounded by a ring of light, resembling a halo.

NGC 6505 is acting as a gravitational lens, bending light from a galaxy far behind it. The almost perfect alignment of NGC 6505 and the background galaxy has bent and magnified the light from the ...

NGC 6505 is a well-known galaxy only around 590 million light-years from Earth, and Euclid’s discovery of a spectacular Einstein ring here was unexpected.

The NGC 6505 gravitational lens was discovered by chance in one of the first patches of sky observed by Euclid, just two months after its July 2023 launch and during its mission verification phase.

NGC 6505 is in alignment with another galaxy that is 4.42 billion light-years away and has never been observed and does not have a name, the ESA says.

The galaxy, NGC 6505, itself is not new to scientists and has been studied since the 19th century, Jacqueline McCleary, assistant professor of physics at Northeastern University says. The Einstein ...
