Life of a Star

What is a Neutron Star?

Back

A neutron star is a stage in the life of a star made up of densely packed neutrons. It can sometimes spin and emit beams of radiation, appearing to blink, which is why it is called a pulsar.

What is the first stage of the life cycle of a star?

Back

The first stage of the life cycle of a star is a nebula, which is a large cloud of gas and dust in space.

Where do all stars begin their life?

Back

All stars begin their life in a nebula.

Front

What is a Protostar?

Back

A protostar is the stage that follows a nebula, where the gas and dust begin to collapse under gravity, forming a dense core that will eventually become a star.

What is the Main Sequence phase of a star?

Back

The Main Sequence is the longest phase in a star's life cycle, where it fuses hydrogen into helium in its core, producing energy.

What is a Red Giant?

Back

A red giant is a late stage in a star's life cycle when it has exhausted the hydrogen in its core and begins to fuse heavier elements, causing it to expand and cool.

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, formed from the remnants of a massive star after a supernova.

What is the difference between a White Dwarf and a Neutron Star?

Back

A white dwarf is the remnant of a low to medium mass star that has shed its outer layers, while a neutron star is the remnant of a massive star that has undergone a supernova explosion.
