How are supernovas made?
star explosions
What is the reason behind the occurrence of supernovas?
Supernovas occur when a massive star runs out of fuel and collapses under its own gravity, causing a powerful explosion that releases a huge amount of energy and creates new elements.
Why are supernovas called supernovas?
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
What does a neutron star form?
A neutron star is what is left behind from some supernovas, which occur when a massive star explodes.
Why are blue stars called supernovas?
They are not. A supernova is an explosion of a star. Blue stars usually end their lives in such explosions.
What happens when massive stars collapse?
The collapses star gets squeezed by collapses gas and turns into a black hole.
Where did copper form?
Copper can only form in supernova explosions, when a dead star collapses to become either a neutron star or a black hole.
When a stars core collapses does a giant explosion happen?
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
What is the difference between an average star and a massive star?
Massive stars are brighter, they burn up faster, and they die younger, usually in very energetic explosions.
How are pulsars related to supernovas?
Pulsars are formed during a supernova event when a massive star explodes, leaving behind a dense core called a neutron star. As this neutron star rotates rapidly, it emits beams of radiation that we detect as pulses, hence the name "pulsars." So, pulsars are directly related to the remnants of supernova explosions.
Why do supernovas not appear on the HR diagram?
A supernova is a star saying "The End". The H-R diagram shows they different types of stars by spectral class, color, etc. It was never intended to show the ending of stars. On most H-R diagrams, you will find at the top, or occasionally top right, a place for "Supergiants". Some of those stars will eventually become supernovas. To be absolutely clear: A supernova isn't a type of star - it is the "end" of a type of star.
What makes a supernova occur in a star's lifecycle?
A supernova occurs in a star's lifecycle when it runs out of fuel and its core collapses, causing a massive explosion.
