The Squid Galaxy's neutrino game just leveled up

In space, energetic neutrinos are usually paired with energetic gamma rays. Galaxy NGC 1068, however, emits strong neutrinos and weak gamma rays, which presents a puzzle for scientists to solve. A new paper posits that helium nuclei collide with ultraviolet photons emitted by the galaxy's central region and fragment, releasing neutrons that subsequently decay into neutrinos without producing gamma rays. The finding offers insight into the extrem…

The Squid Galaxy’s Neutrino Game Just Leveled Up

Eddie Gonzales Jr. – MessageToEagle.com – Buried deep in the ice in the Antarctic are “eyes” that can see elementary particles called neutrinos, and what they’ve observed is puzzling scientists: a remarkably strong neutrino signal accompanied by a surprisingly weak gamma-ray emission in the galaxy NGC 1068, also known as the Squid Galaxy. NGC 1068, […]
