A newly discovered galaxy is challenging what scientists thought they knew about galactic collisions. Located 567 million light-years away, LEDA 1313424 is the first known galaxy to feature nine ...

"They're so rare, and they're incredibly useful scientifically," said Conor O'Riordan of the Max Planck Institute for Astrophysics.

It’s so rare that less than 1% of galaxies have an Einstein ring, O’Riordan said. There are between 100 and 1,000 Einstein ring-like objects known, but only a few tens of them have been ...

In 2007, astronomers discovered the Cosmic Horseshoe, a gravitationally lensed system of galaxies about 5.5 billion ...

The discovery of a galaxy sporting nine concentric rings of stars sheds light on how such ring galaxies form and evolve 1. In a pond hit by a rock, circular ripples spread outwards from the impact ...

This wide field shows the extended stellar halo of NGC 6505 and showcases the Einstein ring, surrounded by colourful foreground stars and background galaxies. Euclid blasted off on its six-year ...

Although this Einstein ring is stunning, Euclid's main job is searching for the more subtle effects of weak gravitational lensing, where background galaxies appear only mildly stretched or displaced.
