News on cosmic rays today

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

Recent Discoveries

• Highest-Energy Cosmic Ray Ever Detected: In February 2023, scientists announced the detection of a cosmic ray with an energy of 1.15 exa-electronvolts (EeV), the highest ever recorded. This event was detected by the Pierre Auger Observatory in Argentina. (Source: Phys.org)
• Cosmic Rays from Distant Galaxies: A study published in January 2023 suggests that some cosmic rays may originate from distant galaxies, rather than just our own Milky Way. The research used data from the Fermi Gamma-Ray Space Telescope to identify gamma-ray bursts that could be associated with cosmic rays. (Source: NASA)

New Research and Theories

• Cosmic Ray Origins: Scientists have proposed a new theory on the origins of cosmic rays, suggesting that they may be produced by the acceleration of particles in the vicinity of black holes. This theory could help explain the high energies observed in some cosmic rays. (Source: Science Daily)
• Cosmic Ray Impact on Climate: A study published in December 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: The Conversation)

Observatories and Missions

• The Pierre Auger Observatory: The Pierre Auger Observatory, located in Argentina, has been detecting high-energy cosmic rays since 2004. The observatory is currently upgrading its detectors to improve its sensitivity and ability to detect even higher-energy particles. (Source: Pierre Auger Observatory)
• The IceCube Neutrino Observatory: The IceCube Neutrino Observatory, located at the South Pole, has been detecting high-energy neutrinos and cosmic rays since 2013. The observatory is currently exploring the connection between cosmic rays and neutrinos. (Source: IceCube Neutrino Observatory)

Upcoming Missions

• The Square Kilometre Array (SKA): The SKA, a next-generation radio telescope, is expected to be completed in the mid-2020s and will have the ability to detect cosmic rays with unprecedented precision. (Source: SKA Organisation)
• The Cherenkov Telescope Array (CTA): The CTA, a next-generation gamma-ray observatory, is expected to be completed in the late 2020s and will have the ability to detect high-energy cosmic rays and gamma rays. (Source: CTA Observatory)
