Could better understanding of neutrinos unlock secrets about other elements of astronomy and physics, from dark matter to the expansion of the universe?

A TEAM EFFORT. On September 22, researchers announced that the IceCube Neutrino Observatory at the South Pole had detected a high-energy neutrino emanating from one area in space. Following that announcement, roughly 20 other observatories quickly swung into action, setting their sights on the position identified by the IceCube researchers.

Now, after months of observation, those groups have collectively determined the precise source of the high-energy neutrino: TXS 0506+056, a blazar located about 4 billion light-years from Earth (a blazar is a type of elliptical galaxy with a rapidly spinning black hole at its center).

The researchers detail this discovery in a trio of papers published July 12, one in the journal The Astrophysical Journal Letters and the other two in Science.

HIGH-ENERGY NEUTRINOS. By identifying the source of a high-energy neutrino, these researchers may be ushering in an entirely new era in astronomy.

“We’re beginning to do astronomy using means other than light, combining electromagnetic (light) observations with other measurements in what we now call multimessenger astronomy,” Marcos Santander, co-author of one of the Science papers, said in a press release. “This is the first evidence that we have of an active galaxy emitting neutrinos, which means we may soon start observing the universe using neutrinos to learn more about these objects in ways that would be impossible with light alone.”

The identification of TXS 0506+056 as the source of the high-energy neutrino is also a shining example of what can happen when scientists work together: they can make discoveries with the potential to change how we explore our universe.

I'm sure that will be true.
Not only that, but it occurs to me that since we're now looking at other components of the Universe, we might happen upon whatever it is advanced civilizations use to communicate.
They said trillions of neutrinos pass through our bodies every second.... That's pretty incredible.
