"Churning galaxy boasts a fiery halo of baby stars"

In summary, galaxies churn through gravitational interaction between stars and celestial objects, which can take millions to billions of years. The resulting fiery halo of baby stars is caused by the compression of gas and dust. While we cannot observe the churning process in real time, it is a common phenomenon in the universe and contributes to galaxy evolution.

Very cool. Thanks for posting.
 

1. How does a galaxy churn?

A galaxy churns through a process called gravitational interaction, where the gravitational forces between stars and other celestial objects cause them to move and interact with each other.

2. What causes the fiery halo of baby stars in a churning galaxy?

The fiery halo of baby stars is caused by the high levels of gas and dust being churned up and compressed during the gravitational interactions. This triggers the formation of new stars.

3. How long does it take for a galaxy to churn?

The churning process can take millions to billions of years, depending on the size of the galaxy and the gravitational forces at play.

4. Can we observe the churning process in real time?

Unfortunately, the churning process happens on a timescale that is too long for us to observe in real time. However, we can study the effects and aftermath of churning in galaxies through telescopes and other instruments.

5. Are churning galaxies common in the universe?

Yes, churning galaxies are a common phenomenon in the universe, especially in larger galaxies. It is an important part of galaxy evolution and contributes to the overall complexity and diversity of the universe.
