1. An asteroid
2. A black hole
3. A comet
4. A dying star

Answer 1

Correct Answer - Option 4 : A dying star

The correct answer is A dying star.

• A supernova is the explosion of a star at the end of its life.
• It can emit more energy in a few seconds than our sun will radiate in its lifetime of billions of years.
• Supernova is the largest explosion that takes place in space. 
• A supernova happens where there is a change in the core, or center, of a star.
• Supernovas are often seen in other galaxies. But supernovas are difficult to see in our own Milky Way galaxy because dust blocks our view.
• In 1604, Johannes Kepler discovered the last observed supernova in the Milky Way.
• NASA’s Chandra telescope discovered the remains of a more recent supernova. It exploded in the Milky Way more than a hundred years ago.
• A supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.

•  A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. 
• Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.
• An asteroid is a minor planet of the inner Solar System.
