Researchers found for the first time evidence that even microquasars containing a low-mass star are efficient particle accelerators, which leads to a significant impact on the interpretation of the ...
A team of Chinese researchers has found a giant bubble of ultra-high-energy gamma rays in the Cygnus region of the Milky Way, which reveals the origin of the most energetic cosmic rays ever detected.
"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...
Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong ...
