Astronomers measure cosmic electrons at the highest energies

Scientists find highest energy cosmic ray electrons ever seen
"Understanding these cosmic rays allows us to unveil big particle accelerators in the universe that are often associated with the most violent phenomena."
Astronomers measure cosmic electrons at the highest energies to date
Five telescopes of the H.E.S.S.-collaboration in Namibia are used to study cosmic radiation, especially gamma radiation. With data from 10 years of observations, researchers have now been able to detect cosmic electrons and positrons with an unprecedented energy of more than 10 tera-electronvolts.
Cosmic-Ray Electrons Slamming Earth Are The Most Powerful Ever Seen
The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.
The most energetic cosmic-ray electrons and positrons ever observed
In the most extensive analysis to date, scientists from the H.E.S.S. collaboration have made significant progress in understanding the origin of
Most Energetic Cosmic Ray Electrons Ever Have Been Detected Slamming Into Earth
There are a lot of particles that come from space and rain down on us, every second of every day. If we include neutrinos, we think trillions of them are passing through your body right now, but if we just focus on cosmic rays from beyond the Solar System,
Scientists detect the most powerful cosmic rays ever — and their unknown source could be close to Earth
New research reports the most powerful cosmic rays ever detected. Because the rays lose energy as they travel through space, their detection at high energies means they are likely coming from sources relatively close to Earth.
Twisted light gives electrons a spinning kick: Researchers develop a novel way to control quantum interactions
It's hard to tell when you're catching some rays at the beach, but light packs a punch. Not only does a beam of light carry ...

Lesson 4.4: Energy Levels, Electrons, and Covalent Bonding
This attraction pulls the atoms together. The electrons end up being shared by the atoms in a region around the nucleus of both atoms. Hydrogen atoms are close together. The electron from each atom ...

Most energetic cosmic-ray electrons and positrons ever observed
Scientists have recently identified electrons and positrons with the highest energies ever recorded on Earth. They provide evidence of cosmic processes emitting colossal amounts of energy, the origins ...
