Supernovas occur when a giant star runs out of energy. As it runs out of fuel to keep burning, the star expands massively before collapsing under its own gravitational pull.
When it does, it releases a huge explosion which sends gas, debris and particles in all directions of the cosmos.
Now, scientists say there is evidence that distant supernovas could be detected here on Earth.
University of Colorado Boulder geoscientist Robert Brakenridge has conducted a study to reveal supernova evidence in trees.
Mr Brakenbridge revealed that carbon-14, also called radiocarbon, is a carbon isotope which is only found in trace amounts on Earth.

It is created when cosmic rays bombard the atmosphere of our planet.
However, trees can pick up radiocarbon, so by analysing tree rings, scientists can tell if there has been an increase in radiocarbon.
If there is, it means that a nearby star has released an abundance of cosmic rays.
Mr Brakenbridge said: "These are extreme events, and their potential effects seem to match tree ring records.
