These cosmic collisions compress gas and stimulate large reservoirs of hydroxyl molecules to amplify radio emission. The physical mechanism is very similar to lasers on Earth, but operates at a much ...
An international team of researchers has announced a significant advancement in gravitational-wave astronomy, with the detection of 128 new cosmic collisions involving black holes and neutron stars.
Tens of kilometers above Earth's surface, high-energy particles from outer space constantly strike the atmosphere, creating showers of energetic secondary particles that rain down from the sky.
