Billions and billions of fusion furnaces



In the observable Universe, most of the matter is in a state of fusion.

At the core of billions and billions of stars (a few hundred thousand billion in our Milky Way alone!) hydrogen nuclei are patiently transformed into helium, inundating their environment with light and energy.

Based on the largest image of the Andromeda Galaxy ever made — so large that it would require 600 large-screen HDTVs to view it in real size — the video that NASA released a few days ago shows just a few (a mere hundred million) of these blazing fusion furnaces.
