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 ...

In the vastness of the Universe, some discoveries remind us how much we still have to learn. A recent study on Cosmic ...

"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 ...

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 could mean that jets can be triggered by a far less involved, dramatic interaction of galaxies than a full merger. The large galaxy to the lower right of the quasar appears to be a ring ...

which has recently started scanning billions of galaxies over an area that will eventually span a third of the night sky. “There was this abundantly obvious Einstein ring. There’s not that ...

"There's a very narrow window after the impact when a galaxy like this would have so many rings." So-called ring galaxies are extremely rare in the Universe, and they are thought to be the result of a ...

This creates a spectacular ring of intense emission, and lights up the system like a Catherine wheel on bonfire night. Such systems are very rare and arise from collisions between two galaxies of ...
