Question

What is the name of a celestial object that results from a supernova explosion?

• A. Neutron star
• B. Black hole
• C. White dwarf
• D. All of the above

Hint:

Remember that the death of stars can lead to different remnants: neutron stars, black holes, or white dwarfs, depending on star size.

Answer 1

The Correct Option is D

Step 1: What is a supernova?
A supernova is a huge explosion that happens when a massive star reaches the end of its life and collapses under its own gravity.
Step 2: What remains after a supernova?
The core of the star that survives after the explosion can become different types of objects depending on its size and mass. These include:
- Neutron star: An extremely dense object made mostly of neutrons, formed when the star’s core is compressed tightly but not enough to become a black hole.
- Black hole: If the core’s gravity is very strong, it collapses into a black hole, a point with gravity so strong that nothing, not even light, can escape it.
- White dwarf: For smaller stars, instead of a supernova, they may become white dwarfs, which are dense, hot remnants of stars but not formed from supernova explosions directly. However, some white dwarfs result from less violent end-of-life processes.
Step 3: Why all options?
Since different types of stars produce different remnants after their life ends, all these celestial objects are connected to star death processes, including supernovae for neutron stars and black holes.
Therefore, Option (D) All of the above is correct.
