That's according to a new analysis — part of the biggest census of star - forming regions to date — that focused on stars eight times the mass of our sun or larger (the size that eventually explode as supernovae) at a very early stage in their lifetime, when they'd still be inside the clouds of gas and dust where they formed.

And then I also thought about the fact that over the history of the life of the universe, neutrinos are not just produced by the sun, but when stars explode in a supernova, the most brilliant fireworks in the universe, as brilliant as those fireworks are, less than 1 percent of the energy of the star is coming out in light; 99 percent is coming out as neutrinos and so neutrinos are being, [and] every time [a star explodes there's] an incredible burst of neutrinos.

Core collapse supernova (CCSN) rates suffer from large uncertainties as many CCSNe exploding in regions of bright background emission and significant dust extinction remain unobserved.
