“IceCube detects ghost particles with 10 billion times the energy of solar neutrinos”

Key points

• IceCube detects extremely energetic neutrinos from distant cosmic sources.
• The neutrinos have energies 10 billion times higher than solar neutrinos.
• IceCube is a massive observatory buried in Antarctic ice.
• Neutrinos are ghost-like particles that interact very weakly with matter.
• The discovery highlights neutrinos’ potential to reveal extreme cosmic events.
