Einstein rings are examples of strong gravitational lensing, O’Riordan said, a phenomenon that acts like a magnifying glass in the universe, revealing celestial objects and light from distant ...

This NASA/ESA Hubble Space Telescope image offers us the chance to see a distant galaxy now some 19.5 billion light-years ...

Einstein rings of light are produced when two galaxies are almost perfectly aligned, with one behind the other from a fixed perspective. They are one of the best examples we have of gravitational ...

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 ...

It's two galaxies, many billions of light-years apart, combined into one by a rare cosmic phenomenon called an Einstein ring. It's an optical illusion. Published recently as the James Webb Space ...

Astronomers using the powerful James Webb Space Telescope to survey distant galaxies spotted an unusual, chance phenomenon called an "Einstein ring." It's not an actual object, but a warped ...
