kilonovae

A kilonova is a powerful cosmic explosion that occurs when two dense neutron stars merge. This collision releases enormous energy and creates a burst of light that can outshine entire galaxies for a short time. It also produces heavy elements like gold and platinum, which are scattered into space. Kilonovae are important because they help scientists understand the origins of many heavy elements and provide clues about gravitational waves—ripples in spacetime caused by such cosmic events. These events are rare but can be detected across vast distances, offering valuable insights into the universe's extreme phenomena.
