Cosmic rays are high-energy particles that constantly bombard Earth from space and are influenced by the sun's magnetic activity. When the sun is active, fewer of these particles reach Earth; when the ...

Cosmic rays traveling through space may provide enough energy to sustain life even in incredibly cold and dark environments, a new study suggests. The staggeringly energetic neutrino likely came from ...

What processes other than water and energy could be responsible for creating life on other worlds? This is what a recent study published in the International Journal of Astrobiology hopes to address ...
