Spectacular New Einstein Cross Discovered Warping Space-Time

Posted by in category: space

A massive galaxy has created a rare distortion in the path of light that has traveled billions of years to reach us from a more distant galaxy.

It’s called an Einstein cross – when the curvature of space-time around a massive foreground object splits the light behind it into four, like the points of a cross. Its confirmation and analysis adds to a slowly growing catalog of these rare alignments, which can help us better understand the more distant reaches of the Universe.

A paper detailing the system has been accepted by The Astrophysical Journal Letters, and is available on preprint resource arXiv.
