Nova

A Nova is an astronomical event characterized by a sudden, explosive burst of light that gradually fades. It results from the interaction of two stars orbiting a shared center of gravity, leading to a dramatic increase in brightness.

What happens to the light of a nova after its initial explosion?

• It fades away eventually.

• It remains constant.

• It becomes brighter over time.

• It changes color.

What is a nova primarily a result of?

• A planet's collision.

• A black hole's influence.

• Two stars interacting.

• A single star's explosion.

How many stars are involved in the formation of a nova?

• Three

• Two

• Four

• One

What do the two stars in a nova do?

• They merge into one star.

• They move away from each other.

• They orbit a common center of gravity.

• They collide with each other.

What is the common center of gravity in a nova system?

• A point where the stars collide.

• A shared focal point of their orbits.

• The center of the larger star.

• The midpoint between the stars.
