Cosmic rays 2017 news
Here are some notable news stories and discoveries related to cosmic rays from 2017:
- Record-breaking cosmic ray event: In January 2017, the Pierre Auger Observatory in Argentina detected a record-breaking cosmic ray event, with an energy of 2.5 x 10^20 electronvolts (EeV). This is the highest energy ever recorded for a cosmic ray particle. (Source: Phys.org)
- Cosmic rays from outside the galaxy: Researchers from the University of Chicago and the University of Utah used data from the Fermi Gamma-Ray Space Telescope to study the origins of cosmic rays. They found that a significant portion of cosmic rays come from outside the Milky Way galaxy, likely from nearby galaxies or galaxy clusters. (Source: ScienceDaily)
- Cosmic ray acceleration in supernovae: A team of scientists from the University of California, Berkeley, and the University of Chicago used computer simulations to study the acceleration of cosmic rays in supernovae explosions. They found that cosmic rays can be accelerated to incredibly high energies in these events, potentially explaining the origin of the highest-energy cosmic rays. (Source: Phys.org)
- Cosmic ray detection with the IceCube Neutrino Observatory: The IceCube Neutrino Observatory at the South Pole detected a high-energy cosmic ray event in March 2017, which was later confirmed to be a neutrino event. This marked the first time that a cosmic ray event was detected using the IceCube detector. (Source: ScienceDaily)
- Cosmic ray research with the Alpha Magnetic Spectrometer (AMS): The Alpha Magnetic Spectrometer (AMS) on the International Space Station continued to collect data on cosmic rays in 2017. Researchers used this data to study the properties of cosmic rays and search for signs of dark matter. (Source: NASA)
- Cosmic ray effects on Earth's atmosphere: Scientists from the University of Colorado Boulder used computer simulations to study the effects of cosmic rays on Earth's atmosphere. They found that cosmic rays can influence the formation of clouds and the Earth's climate. (Source: ScienceDaily)
These are just a few examples of the many exciting developments in the field of cosmic ray research in 2017.
