Supernovae, Neutron Stars, Black Holes

Front

What is a Supernova?

Back

A Supernova is a powerful and luminous explosion of a star, marking the end of its life cycle, which can outshine entire galaxies for a short period.

Front

How can Supernovae be detected?

Back

Supernovae can be detected in all but galaxies at extremely large distances.

Front

What nuclear reaction allows a Supernova core to collapse?

Back

The nuclear reaction that allows the core to collapse is Electron Capture.

Front

What is believed to be at the center of most galaxies?

Back

Most galaxies are thought to have a Super Massive Black Hole at their centers.

Front

What is the minimum mass a Supernova must have?

Back

A Supernova will have at least 1.4 Solar masses.

Front

What can result from a Supernova explosion?

Back

The result of a Supernova explosion can be a Pulsar, a Neutron Star, or a Black Hole.

Front

What is a Neutron Star?

Back

A Neutron Star is the remnants of a massive star that has undergone a Supernova explosion, composed almost entirely of neutrons.

Front

What defines a Black Hole?

Back

A Black Hole is a region of space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is the difference between a Pulsar and a Neutron Star?

Back

A Pulsar is a type of Neutron Star that emits beams of radiation out of its magnetic poles, which can be detected as pulses.

Front

What is the role of gravity in the formation of a Black Hole?

Back

Gravity plays a crucial role in the formation of a Black Hole by collapsing the core of a massive star under its own weight.
