IceCube's Neutrino Map Reveals Ghostly Particles in the Milky Way
Originally Published 2 years ago — by Universe Today
The IceCube Collaboration has created a map of high-energy neutrino emissions from the Milky Way, revealing that our galaxy produces far fewer neutrinos than many distant galaxies. Neutrinos are tiny, massless particles that come from galactic and cosmic sources, as well as cosmic ray interactions with Earth's atmosphere. The team of scientists faced challenges in sifting out the sparse numbers of high-energy neutrinos from galactic sources due to background noise. The findings raise questions about why the Milky Way lacks these particles and where the high-energy sources exist. Further analysis by IceCube is expected to shed light on the particle accelerators in our galaxy.
