Neutrino astronomy

Neutrino astronomy is a type of astronomy that uses neutrinos to learn more about stars, galaxies, and other things happening in space. Neutrinos are tiny particles (almost like the tiniest grains of sand) that travel through space at the speed of light. They don't get slowed down by things like clouds or dust, so we can use them to see things that are too far away for even the strongest telescopes. When neutrinos hit something like a star or a planet, they give off a tiny amount of light, which we can detect. By measuring how many neutrinos are coming from different parts of space, scientists can learn new things about what's out there.
