New Study Shows Supernovas Influence Earth’s Long-Term Climate And More
cosmic rays earthA new study shows how supernovas influence Earth’s climate. The implication is a surprisingly influential role of stellar processes in terrestrial evolution.
A supernova is one of nature’s greatest explosions. It’s the endpoint of the life of certain types of stars that occurs with the outpouring of vast amounts of energy making the luminosity of the explosion many billions of times brighter than our Sun. [emphasis, links added]
In doing so, supernovas scatter heavy elements throughout the cosmos allowing the formation of new stars, planets, and you and I. During the explosion, they also propel protons and atomic nuclei at close to the speed of light.
These are known for historical reasons as cosmic rays, and they pervade the galaxy and beyond. New research extends their influence on the long-term biodiversity of life on Earth.
