Researchers recently confirmed that a gravitational lens effect discovered in 2021 is an Einstein Cross, and the images are fascinating. An Einstein Cross is a special case of gravitational lensing — where a massive object like a galaxy cluster magnifies something behind it by bending the light with its massive gravity — and if everything is positioned just right, you get four ‘duplicate’ images spread out like an X.
This particular Einstein Cross “shows a massive red foreground galaxy. Around it, four blue lights are arrayed; these are duplicated images of a more distant lensed galaxy.” (Science Alert) (arXiv)
