The ring of light surrounding the centre of the galaxy NGC 6505, captured by ESA’s Euclid telescope, is a stunning example of an Einstein ring. 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 background galaxy into a spectacular ring. This rare phenomenon was first theorised to exist by Einstein in his general theory of relativity. This wide field shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colourful foreground stars and background galaxies.
