A team of scientists has detected the presence of a high-energy neutrino — a particularly elusive particle — in the wake of a star’s destruction as it is consumed by a black hole.

This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays — the highest energy particles in the Universe.

Smoking gun: After the supermassive black hole tore the star apart, roughly half of the star debris was flung back out into space, while the remainder formed a glowing accretion disc around the black hole.

The system shone brightly across many wavelengths and is thought to have produced energetic, jet-like outflows perpendicular to the accretion disc.

A central, powerful engine near the accretion disc spewed out these fast subatomic particles.
