Recently Astro Boffins have observed a dull, ghostly glow of stars belched from ancient galaxies which, NASA revealed were gravitationally ripped apart several billion years ago.
The US and European Space Agency’s Hubble telescope have spotted the frenzied, straying stars. The Hubble telescope is the only instrument capable of making such an observation because of its infra-red sensitivity to extremely dim light, NASA said.
NASA said, “The chaos happened 4 billion light-years away, inside an enormous collection of nearly 500 galaxies named Pandora’s Cluster or Abell 2744 (which weighs roughly more than 4 trillion solar masses).”
Moreover, “the scattered stars are no longer bound to any one galaxy, and float generously between galaxies in the cluster. Hubble astronomers observed the light from the orphaned stars and collected forensic proof that proposes as many as 6 galaxies were frayed to pieces inside the cluster over a period of 6 billion years,” NASA revealed.
On the basis of computational modeling of the gravitational dynamics among galaxies in a cluster, researchers believe that the galaxies may have been as big as our Milky Way. The Astro Boffins revealed that the combined light of about 200 billion evicted stars added nearly 10% of the cluster’s brightness.
Mireia Montes of the The Instituto de Astrofísica de Canarias said, “The results are in good agreement with what has been predicted to happen inside massive galaxy clusters.”
