A team of international scientists has discovered a rare cosmic formation which has never been seen before. Only about a dozen Einstein Crosses have been found in the universe to date. This makes them rare, yet the latest discovery makes them even more intriguing. An Einstein Cross only has four images. But this one has an extra image in the middle. Researchers at Rutgers University were shocked when a French astronomer sent them the photo. Pierre Cox, a French astronomer, Research Director at the French National Centre for Scientific Research and the study's lead author, first spotted the anomaly. He thought it was a glitch or that something was wrong with the instrument.Also Read: <a href="https://www.wionews.com/trending/nasa-is-no-longer-a-space-agency-its-new-official-status-is-pretty-shocking-here-s-what-happened-1758101223444">NASA is no longer a space agency.

When the light from a distant galaxy is bent by the gravity of galaxies in front of it, four images are created that sit at about 90 degrees from each other. The gravity of the foreground body warps space-time, making it act like a lens.&nbsp;Andrew Baker, a Professor in the Department of Physics and Astronomy in the School of Arts and Sciences at Rutgers, showed the photo of the Einstein Cross to his colleague, theoretical astrophysicist Charles Keeton, and asked, "Have you ever seen an Einstein Cross with an image in the middle?" Keeton was surprised. "You can't get a fifth image in the centre unless something unusual is going on with the mass that's bending the light," Keeton said. There had to be something at the centre that was making this fifth image.Also Read: <a href="https://www.wionews.com/science/nasa-says-a-new-island-has-emerged-in-alaska-in-just-40-years-1758021271478">NASA says a new island has emerged in Alaska in just 40 years</a>&nbsp;A regular Einstein Cross has four objects, while the fifth image is present too close to the central lensing object, which makes it invisible.

What Stephen Hawking’s 'Black Hole Evaporation Theory' really means for universe?

Black holes don’t just pull in matter, they also bend space and time itself. Step too close, and the way you experience time could be completely different from someone far away. Here’s why that happens.
