LONDON: NASA just revealed that the Hubble Space Telescope has captured some stunning images of a set of wispy, eerie, goblin green cosmic objects that were actually “ghosts” of quasars, once shimmering with life but faded away and died out.
These ethereal, cosmic objects were captured by Hubble and are actually eight separate galaxies that were once active and illuminating for a short time that is caused by ultraviolet radiation blasts from quasars.
Quasars are powered by gigantic black holes found in galactic cores that emit massive amounts of energy as they consume cosmic gas and dust from their environment. According to Bill Keel from the University of Alabama, these quasars are still not bright enough that would be a by-product of a recent cosmic activity: this is a record of something that occured in the past.
