This tells us that Type Ia supernova are not caused by the core collapse of a star, but rather some kind of thermal runaway effect. The most popular model for Type Ia supernovae is that they are ...

For example, Type II supernovae, also known as core-collapse supernovae are known to produce Titanium-44, which is an ...

At least two mass extinction events in Earth's history were likely caused by the 'devastating' effects of nearby supernova explosions, a new study suggests. Researchers say these super-powerful blasts ...

The first type of supernova is a core-collapse supernova ... These suns are born, burn, and die in about 2.5 million years. The stars that produce core-collapse supernovae take closer to 12 ...

Supernovae occur when massive stars reach the end of their lives, run out of fuel, cool off, and then collapse under the pressure of gravity. The explosions are the biggest humans have ever seen.
