Milky Way black hole producing mysterious particles: NASA

The giant region at the centre of the galaxy could also be manufacturing the mysterious high-energy neutrinos, independent agency scientists have found. If confirmed, this might be the primary time that scientists have copied neutrinos back to a region.

Neutrinos area unit little particles that carry no charge and act terribly infirm with electrons and protons. in contrast to light-weight or charged particles, neutrinos will emerge from deep inside their cosmic sources and travel across the universe while not being absorbed by intervening matter or, within the case of charged particles, deflected by magnetic fields.
The Earth is consistently bombarded with neutrinos from the sun. However, neutrinos from on the far side the system may be millions or billions of times additional energetic.

Scientists have long been looking for the origin of ultra-high energy and really high-energy neutrinos. we tend to currently have the primary proof that associate astronomical supply - the opaque Way's supermassive region - could also be manufacturing these terribly energetic neutrinos, same principle Tibeto-Burman language of the University of Wisconsin in Madison. as a result of neutrinos tolerate material terribly simply, it's extraordinarily troublesome to create detectors that show specifically wherever the lepton came from.

The IceCube lepton Observatory, situated beneath the South Pole, has detected thirty six high-energy neutrinos since the power became operational in 2010. By pairing IceCube's capabilities with the information from the 3 X-ray telescopes, scientists were able to hunt for violent events in area that corresponded with the arrival of a high-energy lepton here on Earth. we tend to checked to visualize what happened once Chandra X-ray Observatory witnessed the largest outburst ever detected from Sagittarius A, the opaque Way's supermassive region, same author Andrea Peterson, conjointly of the University of Wisconsin. and fewer than 3 hours later, there was a lepton detection at IceCube, same Peterson.

In addition, many lepton detections appeared inside a couple of days of flares from the supermassive region. it might be a awfully massive deal if we discover out that Sagittarius A produces neutrinos, same author Amy Barger of the University of Wisconsin. The study was printed within the journal Physical Review D
