Week 15 E and E Solar System Formation

Front

What is a supernova?

Back

A supernova is a massive explosion of a star that occurs at the end of its life cycle, resulting in the star's death.

Front

What causes a nebula to contract and heat up?

Back

Gravity causes the cloud to shrink, and as particles collide, they cause the cloud to heat up.

Front

What happens during a supernova?

Back

A massive star explodes, leading to the release of energy and materials into space.

Front

What is a nebula?

Back

A nebula is a large cloud of gas and dust in space, often the birthplace of stars.

Front

What is the significance of a supernova in the universe?

Back

Supernovae contribute to the formation of new stars and planets by dispersing elements into space.

Front

What is the first spacecraft to land on Mars?

Back

Viking 1 was the first spacecraft to successfully land on Mars.

Front

What is a pulsar?

Back

A pulsar is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation.

Front

What is a black hole?

Back

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is the life cycle of a massive star?

Back

A massive star goes through stages: main sequence, red giant, supernova, and may end as a neutron star or black hole.

Front

What is the role of gravity in star formation?

Back

Gravity pulls together gas and dust in a nebula, leading to the formation of stars.
