Neutrino

6.Neutrino: Recently, Scientists detected a high-energy neutrino using an observatory under construction deep beneath the Mediterranean Sea near Sicily.

• About: Neutrinos are undisturbed by magnetic fields and rarely interact with matter, making them "cosmic messengers" that can be traced back to their source.

oThe research was conducted by KM3NeT (Cubic Kilometre Neutrino Telescope) Collaboration.

oThe neutrino is believed to have originated beyond the Milky Way galaxy, possibly from one of 12 supermassive black holes actively consuming surrounding matter.

oNeutrinos provide insights into the cosmos beyond electromagnetic radiation (light), as they pass through matter without being deflected.

• Unlike cosmic rays, whose paths are altered by magnetic fields, neutrinos travel in straight lines, making them more reliable messengers.
• Detecting neutrinos is complex, requiring large observatories deep underwater or in ice to detect their interactions with matter.
• High-energy neutrinos are produced by extreme astrophysical events like: Black holes consuming matter → Gamma-ray bursts from star explosions → Cosmic rays interacting with background radiation.
