Astronomers have made an extraordinary discovery—a "Carousel Lens," a rare alignment of galaxies that could provide ...

Astronomers have discovered seven distant galaxies aligned with a galaxy cluster; together, they form one of the most unique configurations of galaxies ever seen. This arrangement of warped and ...

Lenses that are less spherical and more elongated, in contrast, can produce a similar phenomenon called an Einstein Cross, in which four distinct images are produced around the lensing galaxy.

Astronomers have identified the closest ever Einstein ring, a rare phenomenon where light from a further-off galaxy is bent by the gravity of a galaxy closer to Earth. The ring was previously ...
