An oval galaxy with weird spirals and a weird bulge in its middle? It's two galaxies, many billions of light-years apart, combined into one by a rare cosmic phenomenon called an Einstein ring.

We have now found dozens of Einstein rings, and one of the more beautiful examples was recently found by JWST, as seen in the image above. The close galaxy in the foreground is an elliptical ...

The elliptical galaxy at the center of this Einstein ring belongs to a galaxy cluster named SMACSJ0028.2-7537. It can be seen as the oval-shaped, featurless glow around the small bright core.

A jaw-dropping new space image shows one galaxy hiding behind another. The rare cosmic phenomenon, called an Einstein ring, occurs when massive objects can bend light due to their gravitational ...

T he James Webb Space Telescope (JWST) has captured one of the most stunning and rare cosmic sights in astronomy: a nearly perfect Einstein ring, formed by the warped light of a distant galaxy ...

The foreground galaxy's mass magnifies and distorts the ... galaxies are in such perfect alignment that they create an ...

The school-bus-sized observatory launched on April 24, 1990 and overcame early setbacks to become one of the most scientifically productive instruments in history. From its vantage point 320 miles ...
