New Energy 'Ghost Particle' Map of Milky Way Opens Window into Cosmos
- Scientists detected high-energy neutrinos emitted from the galactic center of the Milky Way for the first time, producing a new map of the galaxy in these nearly massless particles rather than light.
- The IceCube Neutrino Observatory in Antarctica analyzed a decade of data to identify hundreds of neutrinos originating in the galactic plane.
- Neutrinos rarely interact with matter and radiation, earning them the nickname "ghost particles," but IceCube uses optical sensors in Antarctic ice to detect them.
- The findings provide evidence that the Milky Way is a source of high-energy neutrinos and could help reveal the origins of cosmic rays and study the structure of the galaxy.
- While more data is needed to confirm the results, the discovery demonstrates the potential of neutrinos to open a new window into astrophysical phenomena and the universe.
