Question

Name the star that suddenly increases its brightness due to a catastrophic explosion?

• A. Supernova
• B. Comet
• C. Asteroid
• D. Meteor

Hint:

Supernovas are massive star explosions — remember them as bright, short-lived stellar outbursts.

Answer 1

The Correct Option is A

Step 1: Understanding stellar events
Stars undergo different phenomena during their lifecycle. One such event is a supernova, a powerful and luminous explosion.
Step 2: Characteristics of a Supernova
A supernova occurs when a massive star exhausts its nuclear fuel and collapses, leading to a catastrophic explosion that significantly increases the star’s brightness for a short time.
Step 3: Evaluate other options
A comet is an icy body that glows when near the sun but doesn't explode.
An asteroid is a rocky body, typically between Mars and Jupiter.
A meteor is a space rock that burns upon entering Earth’s atmosphere.
Hence, only "Supernova" fits the description.
