Apr 5, 2024 · A message claiming that Google, NASA, BBC, and CNN have warned people to turn off their mobile phones, laptops, and electronic devices between 12:30 a.m. and 3:30 a.m. tonight is being widely shared across social media platforms (here, here, & here). The message asserts that Earth will experience the highest radiation tonight as cosmic rays pass near it during this time.

Feb 14, 2013 · The Fermi results concern two particular supernova remnants, known as IC 443 and W44, which scientists studied to prove supernova remnants produce cosmic rays. IC 443 and W44 are expanding into cold, dense clouds of interstellar gas. These clouds emit gamma rays when struck by high-speed particles escaping the remnants.
Feb 14, 2013 · Origin of cosmic rays is 'exploded stars'. Scientists have conclusive proof that many cosmic rays raining down on Earth come from distant exploded stars. Cosmic rays - mostly ultra-fast proton ...

Feb 16, 2010 · Feb 16, 2010. Article. New images from NASA’s Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe’s most energetic particles – cosmic rays.
Apr 21, 2016 · Karen C. Fox. NASA Goddard Space Flight Center, Greenbelt, Maryland. 301-286-6284. karen.c.fox@nasa.gov. Most of the cosmic rays that we detect at Earth originated relatively recently in nearby clusters of massive stars, according to new results from NASA’s.
Feb 14, 2013 · Cosmic rays: Fermi telescope settles mystery of origin. Scientists have conclusive proof that many cosmic rays raining down on Earth come from distant exploded stars. Cosmic rays - mostly ultra-fast proton particles - would threaten life if not for the shielding of our planet's atmosphere and magnetic field. Nasa's Fermi telescope was used to ...
