Cosmic rays are hitting us all the time. What are they?
The greatest mysteries of the universe don’t have to reside in black holes or far off galaxies. Some of them actually surround us all the time — and even sail right through our bodies.
One such mystery is cosmic rays, radiation from space made of tiny bits of atoms. They’re not harmful to humans, but they perplex physicists, who are trying to figure out where the very most powerful cosmic rays come from.
Many are much too powerful to have originated from our sun or an exploding star. And because they don’t often travel in a straight line, it’s hard to pinpoint their true origin.
The answer to the mystery of cosmic rays could involve objects and physical phenomena in the universe that no one has ever seen or recorded before. And physicists have several enormous experiments around the world underway now devoted to cracking the case.
