An international team of astronomers has investigated a very high energy (VHE) emission from the radio galaxy Messier 87. Results of the study, published December 16 on arXiv.org, could help us better understand the nature ...
Recent advances in the observation of high-energy radiations, including X-rays and gamma-rays, have unveiled many high-energy aspects of the universe. To achieve a complete understanding of these radiations, however, researchers ...
Known as a gamma-ray burst, the intense light captured in the night sky resulted from one of the biggest and hottest explosions in the universe, occurring shortly after the Big Bang.Intense light from the enormous explosion ...
