Indian researchers discover 3 black holes from 3 galaxies

The active galactic nucleus is a compact region at the center of a newly discovered galaxy The active galactic nuclei release huge amounts of ionized particles and energy into the galaxy and its environment These ultimately contribute to the growth of the medium around the galaxy and ultimately the evolution of the galaxy itself.

Chinese space telescope to observe 'big eaters'

When a black hole swallows too much, the excess matter is converted into two jet-flows perpendicular to the accretion disk of the black hole, which is like a glutton with a bloated belly belching.

Why some galaxies have become barren

Over the last few billion years, a mysterious kind of galactic warming has caused many galaxies to change from a lively place where new stars formed every now and then to a quiet place devoid of fresh young stars.
