The Milky Way’s secret

Context:

2020 Nobel Prize in physics has been awarded to Roger Penrose, Reinhard Genzel and Andrea M. Ghez for their work on black holes.

Important terminologies:

1. Event Horizon:

It is defined as a notional boundary around a black hole beyond which no light or other radiation can escape.

2. Quasars:

A quasar is an extremely luminous active galactic nucleus (AGN), in which a super massive black hole with very high mass is surrounded by a gaseous accretion disk.
Quasars are found in the centres of some galaxies and powered by gas spiralling at high velocity into an extremely large black hole.
Quasars give off enormous amounts of energy.

3. Sagittarius A*:

Sagittarius A* is a bright and very compact astronomical radio source at the Galactic Centre of the Milky Way.
Sagittarius A* is the location of a super massive black hole, similar to those at the centres of most, if not all, spiral galaxies and elliptical galaxies.
