One of the most powerful cosmic rays ever detected may have come from this nearby starburst galaxy
Detected in 2021, the Amaterasu particle ranks among the most energetic cosmic rays ever observed, carrying an estimated 244 exa-electronvolts. Its apparent arrival from a nearly empty region of space ...
LHAASO has uncovered that micro-quasars, black holes feeding on companion stars, are powerful PeV particle accelerators. Their jets produce ultra-high-energy gamma rays and protons that exceed ...
Some of the universe's most extreme explosions leave behind almost no trace. The original explosion is unseen, but our observations can capture the long-lived echo it leaves behind as the shock front ...
Scientists are exploring the origins of the Amaterasu particle, an extremely energetic cosmic ray first detected in 2021, which carries unprecedented energy levels.
A newly detected X-ray transient may reveal the first direct evidence of an intermediate-mass black hole consuming a white dwarf. A newly observed cosmic outburst is giving astronomers a rare glimpse ...
In May 2021, an unusually high flux of cosmic rays bombarded Earth. According to a team of astrophysicists from the Raman Research Institute in Bengaluru and the University of Florida in the United ...
CC0 Usage Conditions ApplyClick for more information. Nearly 100 years ago, scientists detected the first signs of cosmic rays—subatomic particles (mostly protons) that zip through space at nearly the ...
Life on Mars sounds like something from a "Doctor Who" episode. But a study published in the International Journal of Astrobiology challenges the science fiction notion of that idea. The research ...
