NASA’s Hubble Space Telescope has observed faint glow of stars, ejected from a cluster of galaxies which were ripped about six billion years ago and is situated four billion light years away from us, according to a NASA press release. This light has emerged from a collection of nearly five hundred galaxies nicknamed “Pandora’s Cluster”, also known as Abell 2744. It was recorded as one of the faintest and most distant galaxies ever seen.

The faint glow is referred to as “ghostly” spark, for it is emerging out of remnants of dead stars. Scientists are superficially considering this discovery as the observation is made during the times of Halloween.

By scrutinizing the light closely, Hubble telescope has enabled scientists to assemble forensic evidences affiliated to the ripped galaxies. And after several deductions, it was found that as many as six galaxies were the part of cluster. As estimated by the team, combined light of about two hundred billion outcast stars contributes approximately ten percent of the cluster’s brightness.

Gashing of these galaxies is majorly attributed to gravitational field existing between the galaxies. It is comprehended that these galaxies would have been “taffy” if they plunged through the center of galaxy cluster, where gravitational tidal forces are the strongest.

Till now, astronomers were of firm belief that the light from scattered stars can be detected after these galaxies get disassembled. Since, in this case the glow is revealed from the galaxy’s core, it was quite difficult to be noticed. Perhaps, this is the reason, why astronomers took so long i.e. three years, for this discovery.

“The Hubble data revealing the ghost light are important steps forward in understanding the evolution of galaxy clusters”, said Dr. Ignacio Trujillo of The Instituto de Astrofisica de Canarias (IAC), Santa Cruz de Tenerife, Spain. “It is also amazingly beautiful in that we found the telltale glow by utilizing Hubble’s unique capabilities.
