Cosmic rays 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 discovery was made using 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 Origins: Researchers have made progress in understanding the origins of cosmic rays, with a study published in April 2022 suggesting that they may be produced by supernovae explosions in the Milky Way. [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 completed in the late 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 studying cosmic rays and their composition until at least 2025. [Source: NASA]

Recent Events and Anniversaries

  1. The 100th Anniversary of the Discovery of Cosmic Rays: In 2022, scientists celebrated the 100th anniversary of the discovery of cosmic rays by Victor Hess in 1922. [Source: Physics Today]
  2. The 50th Anniversary of the First Cosmic Ray Detector: In 2022, scientists celebrated the 50th anniversary of the first cosmic ray detector, which was built by the University of Utah in 1972. [Source: University of Utah]

Interesting Facts and Quotes

  1. Cosmic Rays are Everywhere: "Cosmic rays are all around us, all the time. They're like a constant rain of high-energy particles from space." - Dr. Francis Halzen, University of Wisconsin-Madison [Source: Physics Today]
