The red arc at the center of this Hubble Space Telescope image is a distant galaxy, called HerS 020941.1+001557. It appears to be partially circling another galaxy, SDSS J020941.27+001558.4, and ...

Einstein rings happen when a lensed object lines up with its magnifying object. Depending on how precisely they align, an Einstein ring can either look like a full or partial circle around the ...

As predicted by Einstein, the first complete Einstein ring was found in 1998 by the Hubble Space Telescope. Wishing you clear skies and wide eyes.

"This discovery was partly serendipity! But, we believe there are many more such opportunities hidden in Hubble data." ...

This Hubble Space Telescope image features a remote galaxy, called HerS 020941.1+001557, which appears as a red arc that partially encircles the foreground elliptical galaxy SDSS J020941.27+001558 ...
