Astronomy Every second, a trillion of the elusive ghost particles, the neutrinos, pass straight through your body. Now, astrophysicists from the University of Copenhagen have mapped how many ghost particles all the stars in the Milky Way send towards Earth, and where in the galaxy they originate. This new map could help us track down these mysterious particles and unlock knowledge about our Galaxy that has so far been out of reach.

Leopard-spotted deposits in fossilized mud on Mars may have been left behind by living organisms.
