A supernova occurs somewhere in the universe every 10 seconds. Supernovae are sources in our universe of elements, radiation, and neutrinos. Supernovae are cosmic particle accelerators that can be replicated in a laboratory in a project made possible with DOE Office of Science Fusion Energy Science program support.

What stage does a supernova occur?

Stage 3 - In the next million years a series of nuclear reactions occur forming different elements in shells around the iron core. Stage 4 - The core collapses in less than a second, causing an explosion called a Supernova, in which a shock wave blows of the outer layers of the star.

How often does supernova occur?

Although supernovae are relatively rare events, occurring on average about once every 50 years in the Milky Way, observations of distant galaxies allowed supernovae to be discovered and examined more frequently.
