Neutrino
A neutrally charged particle that is very difficult to detect due to its being nearly massless. Neutrinos play a crucial role for understanding the mechanisms that keep the Sun on, similarly to x rays' role in radiography. Neutrinos also carry with them the weak and still ill-detected signals of far astrophysics phenomena such as star collapses, because they are not absorbed in outer space.
