IN a huge breakthrough for astrophysics, scientists believe that they have detected the first neutrino to have originated from outside our galaxy.
Neutrinos are invisible yet high-energy particles that are one of the fundamental ingredients of the universe.
Little is known about them due to the fact that they rarely interact with other particles apart from when they collide head on.

Neutrinos will sometimes collide with particles on the ice
However, neutrinos may hold some secrets to the history of the universe as when they do collide with other particles, a chain reaction occurs that lets scientists trace the neutrinos back to their original source – thus unravelling some of the mysteries of the universe.
They often pass through Earth but because they are not influenced, they go undetected.
