A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or core-collapse. This first type happens in binary star systems where at least one star is a white dwarf, and they...
Type II Supernova Stars exist in a delicate balance between their owngravityand the fusion engine they ignite. The sheer mass of a star is enough to crush lighter elements together into heavier ones, which releases energy. Enough energy released in this fashion can exert a physical pressure on...
A type I supernova involves the collapsing core of a high mass star. True False A Type Ia Supernova is an example of a ___. How does the luminosity of a giant star compare with the luminosity of a main- sequence star of the same spectral class? Is...

Another type of supernova, called a thermal runaway supernova, can occur when two stars orbit each other, and one or both of those stars is awhite dwarf. White dwarfs are the remains of a star roughly the size of our Sun when it runs out of fuel. If the stars in one of these bi...
eye, a supernova appears to be a bright new star, but it’s not a new star. It’s a dying star.However, the shock waves from a supernova excite nearby clouds of hydrogen gas, causing them to compress, which does form new stars, and that process emits a distinctive type of ...
There are two main types of supernovae. One is where a massive star – much bigger than our sun — burns all its nuclear fuel and collapses in on itself, which ignites a supernova explosion. Type Ia supernovae, however, are different. Smaller stars eventually turn into white dwarfs at...
What produces a type 1 supernova? What is one fermi? What is dark energy? What kind of star is most likely to become a white-dwarf supernova? What is a black hole? What exactly is transmutation? What are some differences between a nova and a supernova?
And by using Type Ia supernovae as standard candles, researchers have been able to map entire galaxies' distances from us and determine that the universe is expanding ever more rapidly [source: Cal Tech]. But stars leave more than an electromagnetic signature behind. When a star explodes, it...
