The South Pole IceCube Neutrino Observatory – the biggest and strangest telescope in the world – has detected the first neutrino emissions from within the Milky Way, an achievement that will shape how astronomers view our galaxy.
Neutrinos are tiny, electrically neutral particles that pass through most matter undetected. They are created in extreme environments like those surrounding massive black holes, and they travel unhindered through space and matter in a straight path.
