Supernova

Supernova explosions are incredibly bright, capable of outshining entire galaxies. They release more energy in a few weeks than the sun will emit over billions of years. These cosmic events are responsible for creating all the heavy elements found in the universe.

How do supernova explosions compare in brightness to other celestial bodies?

• They are as bright as a small planet.

• They are dimmer than most stars.

• They are only visible with telescopes.

• They can outshine an entire galaxy.

What is remarkable about the energy released by supernovae?

• It is less than the energy released by the sun in a year.

• It is more than the energy the sun emits in billions of years.

• It is equivalent to the energy of a small asteroid.

• It is only measurable in small quantities.

In what time frame do supernovae release their immense energy?

• Over several centuries.

• In a few weeks.

• In a few hours.

• Over a millennium.

Where are all the heavy elements in the universe created?

• In black holes.

• In the core of the Earth.

• In the sun.

• In supernovae.

What role do supernovae play in the universe?

• They prevent the formation of stars.

• They create light elements.

• They are responsible for the formation of heavy elements.

• They absorb energy from galaxies.
