Neutrinos may be the first messengers announcing the next supernova in our Milky Way. 👻🎇 Stars many times more massive than our own sun can explode in a fiery supernova, spewing their guts across the cosmos. (That's the star stuff we're all made of!) An enormous amount of a supernova’s energy, a whopping 99 percent, is carried away by a burst of neutrinos (of all flavors) in a span of about 10 seconds. The core of the collapsing star is incredibly dense, but because neutrinos interact so rarely, they escape from the center even more quickly than the light does. Neutrino observatories will thus be the first places on Earth to see a supernova and can be used to direct optical telescopes to the right part of the sky to witness the arrival of the supernova’s light.
