Scientists with the HESS Observatory have identified the most energetic cosmic electrons ever observed. What could this mean for our understanding of the universe?

That’s less than the energy of a flying mosquito, all the way up to the energy of a tennis ball whacked at 100 kilometers per hour. The vast majority of cosmic rays have very low energies, but there ...

A new paper provides scientists with a groundbreaking tool for understanding cataclysmic events. Physicist Glennys Farrar has ...

Ultra-high energy cosmic rays are orders of magnitude more powerful than the sun's energetic particles: They can reach up to 10 20 electron volts, whereas particles from the sun can reach up to 10 ...

Last April a survey by the Dark Energy Spectroscopic Instrument ... into other particles (this light is the cosmic microwave background radiation that we can still see today).

Mary Kertzman's primary interest is very high energy (VHE) gamma ray astrophysics ... She also is analyzing data from VERITAS, trying to measure the spectrum of cosmic ray electrons. She usually ...

Especially the latter poses a great challenge for long-term space travel, and so people are working on various concepts to protect astronauts’ DNA from being smashed by cosmic rays. This has ...

Our world is constantly bombarded by high-energy particles from various sources ... protective barrier against the majority of these cosmic rays, and there is a measurable increase in radiation ...
