Just 25 light-years from Earth, astronomers have watched a planetary system tear itself apart in real time, catching the dusty aftermath of violent impacts that were once only theoretical. Instead of ...

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.

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.

Neutron collisions are cosmic events of immense power that have the ability to forge some of the universe’s most precious elements, including gold. These astronomical phenomena provide a unique ...

Cosmic strings are artifacts of what the universe looked like in the moments before it rapidly changed from a high-energy to low-energy environment—the Big Bang. Today, scientists believe cosmic ...

Cosmic strings are hypothesised one-dimensional topological defects formed during symmetry-breaking phase transitions in the early Universe. As these strings evolve, they intersect and form loops ...
