Physicists worldwide are continuing their search for dark matter, an elusive type of matter that does not absorb, reflect or emit light and is believed to make up most of the matter in the universe. A type of dark matter ...
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 ...
An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments ...
