Newly discovered optical effect allows IceCube to deduce ice crystal properties

Every second, 100 trillion neutrinos pass through the human body. These tiny, almost massless particles [...]

An image showing a newly discovered PeVatron (in pink) hosted by a supernova remnant (in green) called G106.3+2.7. The supernova remnant is believed to have formed together with the pulsar (in magenta) about 10,000 years ago. Particles accelerated by the shock waves of the supernova remnant interact with the gas in the interstellar medium, producing high-energy gamma-ray emission.
