What is a neutron star?

Back

A neutron star is the collapsed core of a large star which has undergone a supernova explosion. It is incredibly dense, with a radius of about 10 kilometers and a mass 1.4 times that of the sun.

What happens to a star when a cloud of gas and dust blocks its light?

Back

The star will appear dark.

What are the huge clouds of gas and dust in space from which stars form called?

Back

Nebula.

Front

What are planetary nebulas, white dwarfs, and neutron stars?

Back

They are later stages in the life of a star.

Front

What is a white dwarf?

What is a nebula?

Back

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

Front

What is the difference between a white dwarf and a neutron star?

Back

A white dwarf is formed from low- or medium-mass stars, while a neutron star forms from the remnants of massive stars after a supernova.

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages such as nebula, main sequence, red giant, supernova, and then either a neutron star or a black hole.
