Figuring out where cosmic neutrinos come from is tricky—radio telescopes could help find 'ghost particles' origin

Neutrinos are funny little particles that weigh almost nothing, making them one of the universe's most elusive building blocks. They can come from objects as mundane as bananas and as exotic as supernovas—the exploding death throes of massive stars. Most neutrinos stream through space and pass through the Earth without interacting with anything.
