What is a supernova remnant?

Back

A supernova remnant is the expanding material left over after a supernova explosion, which can include gas and dust.

What is spaghettification?

Back

Spaghettification is the stretching effect experienced by objects when they fall into a black hole due to the extreme gravitational gradient.

How does mass affect the bending of time and space?

Back

The more mass an object has, the more it bends time and space, according to the theory of general relativity.

Front

What happens to a star with less than twenty times the Sun's mass when its core collapses?

Back

It becomes a neutron star.

Front

What is a neutron star?

Back

A neutron star is an extremely dense mass of neutrons formed at the core of a supernova, created by the compression of electrons and protons.

Front

What is the life cycle of a high mass star?

Back

A high mass star undergoes nuclear fusion, expands into a supergiant, undergoes a supernova explosion, and can become a neutron star or black hole.

Front

What is the role of gravity in the formation of a black hole?

Back

Gravity causes the collapse of a massive star's core, leading to the formation of a black hole when the core's mass is sufficient.

What is the difference between a neutron star and a black hole?

Back

A neutron star is a dense remnant of a supernova, while a black hole is a region of space where gravity is so strong that nothing, not even light, can escape.

Front

What is the significance of the Chandrasekhar limit?

Back

The Chandrasekhar limit is the maximum mass (about 1.4 solar masses) that a white dwarf can have before collapsing into a neutron star or black hole.

Front

What are pulsars?

Back

Pulsars are rotating neutron stars that emit beams of radiation, which can be detected as pulses when the beam points toward Earth.
