Cosmic ray originated in cataclysmic event | Space

February 27, 2021 Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star. Artist’s concept of a tidal disruption event, when a star comes too close to a supermassive black hole and gets shredded. A situation like this may light up the host galaxy many times greater than its normal brightness. Image via DESY/ Science Communication Lab. Cosmic rays are high-energy particles that travel through space at close to the speed of light. Many origins of cosmic rays have been suggested, and some confirmed; for example, supernova explosions generate them. But supernovae can’t explain the quantity of cosmic rays bombarding Earth at all times, and so cosmic ray origins are still largely mysterious. In particular, high-energy neutrinos are largely unexplained (although some come from blazars). Now, astronomers have pinpointed the origin of a high-energy ne

Scientists link star-shredding event to origins of universe s highest-energy particles

Scientists Capture The First Picture Of A Black Hole A group of scientists has detected the presence of a high-energy neutrino a particularly elusive particle in the wake of a star s destruction as it is consumed by a black hole. Neutrinos as well as the process of their creation are hard to detect, making their discovery, along with that of Ultrahigh Energy Cosmic Rays (UHECRs), noteworthy. This discovery, reported in the journal Nature Astronomy, sheds new light on the origins of Ultrahigh Energy Cosmic Rays the highest energy particles in the Universe. The work, which included researchers from more than two dozen institutions, including New York University and Germany s DESY research center, focused on neutrinos subatomic particles that are produced on Earth only in powerful accelerators.

Ghost particle that crashed into Antarctica traced back to star shredded by black hole

Ghost particle that crashed into Antarctica traced back to star shredded by black hole A black hole gobbled up a star in deep space and flung a high-energy subatomic bullet at the Earth. Don t worry, the planet s doing fine. Listen - 04:14 A star being ripped to shreds after it approaches a black hole. Scientists have detected a neutrino the ghost particle from such an event for the first time. DESY, Science Communication Lab On Oct. 1, 2019, Earth was struck by an invisible, high-energy cosmic bullet moving at almost the speed of light. Trillions of these intergalactic bullets pass through our bodies every
