Hubble finds giant objects near dead quasars

Washington: NASA's Hubble space telescope has clicked a set of wispy, goblin-green objects that are the ephemeral ghosts of quasars that flickered to life and then faded. The glowing structures have looping, helical and braided shapes. These images reveal a set of bizarre, greenish looping, spiral and braided shapes around eight active galaxies.

The galaxies host a bright quasar that may have illuminated the structures. The most active of these galaxy cores are called quasars, where infalling material is heated to a point where a brilliant searchlight shines into deep space. The beam is produced by a disk of glowing, superheated gas encircling the black hole.
