A star torn apart by the gravitational force of a black hole produced high-energy neutrinos, according to new research.
This is only the second time a high-energy neutrino has been traced to a source beyond our galaxy.
Neutrinos are abundant but difficult to detect because they rarely interact with other matter.
While many neutrinos were likely produced, only one was detected.

Many facilities collaborated to trace the neutrino, including N S F's Ice-Cube Neutrino Observatory in Antarctica...

Text, The neutrino was detected five months after the peak brightness of the star's destruction, which was unexpected.
Scientists are still learning a lot about the creation of neutrinos, especially from rare events like this one.
