nasaSep 5, (THAINDIAN NEWS) The Chandra X-Ray Observatory of NASA has come across a cosmic activity that it has named cosmic “ghost”. The scientists who carried out the research believe that the cosmic “ghost” is an evidence of a big eruption that was caused by a super-massive black hole that was as strong and powerful as billion supernovas. As per reports, the source of the cosmic “ghost”, HDF 130, is over 10 billion light years away from the Earth and scientists have mentioned that the eruption took place at the time when black holes and galaxies were being formed in high rates. The so called cosmic “ghost” is around three billion years younger than the Big Bang.

Scientists have named the found X-ray radiation a “ghost” reportedly because the source remains even after all other radiations from the eruption has died away. The X-ray radiation was caught by one of the deepest X-ray images that has been taken by any astronomical devices. The X-ray ghost was located in the Chandra Deep Field-North. Andy Fabian of the Cambridge University, United Kingdom, said to media sources that the “fuzzy object” was noticed in space a few years ago, but the scientists at that time were not sure that they were seeing was something so old. He maintained that the found “cosmic” ghost tells us about what was happening in the galaxy “billions of year ago”.

The co-author of the finding, Scott Chapman, said to media sources that the present finding keeps in front of the researchers the details of the black hole’s eruption billions of years after its expiry. He held that scientists in the present situation do not need to catch the action in happening to understand its big impact.
