High-energy neutrinos ensnared from beyond the solar system
Speedy particles may point to gargantuan black holes or cataclysmic explosions

Ghostly high-energy particles from beyond the solar system have been snagged for the first time by a giant experiment buried under Antarctic ice. The sightings of the particles, called neutrinos, represent a major step toward identifying mysterious astrophysical phenomena that hurl subatomic particles across the universe at extraordinary speeds.
Neutrinos are an intriguing tool for exploring the cosmos. The wispy particles have no charge and rarely interact with matter, allowing astronomers to...
