Chapter 34, Problem 6TE

Solution

To determine: Whether the Milky Way Galaxy have galactic nucleus or not.

Answer:

Milky Way Galaxy does not have an active galactic nucleus.

Explanation:

The small and dense area in the centre of a galaxy is known as an active galactic nucleus. It emits a large amount of energy and has higher luminosity than normal. The energy emitted is in the form of waves like radio, gamma, and optical. This is generally observed in newly formed galaxies.

In the galactic nucleus, a black hole is found at the center of the galaxy, which intakes all material falling into it and the material disappears by the effect of heat and gravitational effect. This heated material emits a vast amount of energy.

Milky Way Galaxy does not contain an active galactic nucleus because it is not a newly born galaxy. Maybe it was having a galactic nucleus, when it was generated.

Conclusion:

Therefore, Milky Way Galaxy does not have an active galactic nucleus.
