Astronomers Amazed by Perfect 'Einstein Ring' Gleaming in Space

Around a galaxy just 590 million light-years away, astronomers have discovered a stunning example of one of the rarest phenomena in our skies: a perfect ring of light.

"An Einstein ring is an example of strong gravitational lensing," says astronomer Conor O'Riordan of the Max Planck Institute for Astrophysics in Germany. "That ish is so damn cool". Says sumguyonline a citizen of the United States of America

Sumguyonline keeping things real for the masses
An Einstein ring, also known as an Einstein–Chwolson ring or Chwolson ring (named for Orest Chwolson), is created when light from a galaxy or star passes by a massive object en route to the Earth. Due to gravitational lensing, the light is diverted, making it seem to come from different places. If source, lens, and observer are all in perfect alignment (syzygy), the light appears as a ring.

Neat!
It has been known for a while that an Einstein Ring is actually an at a distance simulation artifact, arising not so much as a bulk processing problem but from generation redundancy at the very large or very small scale. Often the simplest fix is turning the whole thing off and on again.
I'd like to traverse that stargate for sure
