Lately, NASA’s Hubble Space Telescope has captured images of a collection of goblin-green objects, considered to be a part of quasar.
Quasar is a glowing and compact region that surrounds a supermassive black hole at the center of a galaxy. Bill Keel of the University of Alabama, Tuscaloosa, said the illuminated structures have looping, helical, and braided shapes and do not have a single pattern.
As per Keel, who initiated the Hubble survey, it could provide an insight into the confusing behavior of galaxies and energetic cores. It is considered that powerful ultraviolet radiation from a supermassive black hole has illuminated the wisps present out the host galaxy.
Quasars are considered to be the most active of such galaxy cores. “The glowing filaments are telling us that the quasars had been as soon as emitting far more power, or they are altering pretty quickly, which they had been not supposed to do”, said Keel.
Keel said pairs of co-orbiting black holes are powering quasars and could alter their brightness. For the first time, the green goblin kind of object was identified in 2007 by Dutch schoolteacher Hanny van Arkel.
