Cosmic rays today news

Here are some recent news articles and updates on cosmic rays:

Recent Discoveries

  1. Highest-Energy Cosmic Ray Ever Detected: In August 2022, scientists announced the detection of a cosmic ray with an energy of 8.5 x 10^20 electronvolts (eV), the highest ever recorded. This event was detected by the Pierre Auger Observatory in Argentina. [Source: Science Magazine]
  2. Cosmic Rays from Distant Galaxies: A study published in June 2022 suggests that a significant portion of cosmic rays detected on Earth may come from distant galaxies, rather than our own galaxy, the Milky Way. [Source: NASA]
  3. Cosmic Ray Anisotropy: Researchers have detected a subtle anisotropy in the distribution of cosmic rays, which could be evidence of the presence of dark matter. [Source: Physics World]

Upcoming Missions and Experiments

  1. The Square Kilometre Array (SKA): The SKA, a next-generation radio telescope, is expected to be completed in the mid-2020s and will study cosmic rays in unprecedented detail. [Source: SKA Organisation]
  2. The Cherenkov Telescope Array (CTA): The CTA, a new generation of ground-based gamma-ray observatories, is expected to be operational in the mid-2020s and will study cosmic rays and their interactions with the Earth's atmosphere. [Source: CTA Consortium]
  3. The Alpha Magnetic Spectrometer (AMS): The AMS, a particle detector on the International Space Station, is expected to continue collecting data on cosmic rays until at least 2025. [Source: NASA]

Recent Research and Studies

  1. Cosmic Ray Origins: A study published in April 2022 suggests that cosmic rays may originate from the acceleration of particles in the vicinity of black holes. [Source: The Astrophysical Journal]
  2. Cosmic Ray Propagation: Researchers have developed a new model to study the propagation of cosmic rays through the galaxy, which could help explain their observed anisotropy. [Source: The Astrophysical Journal]
  3. Cosmic Ray Effects on Climate: A study published in March 2022 suggests that cosmic rays may have a significant impact on Earth's climate, potentially influencing the formation of clouds and the global temperature. [Source: Nature Communications]
