Neutron star mergers
Neutron star mergers occur when two neutron stars—extremely dense remnants of massive stars—spiral together and collide. This cosmic event releases an enormous amount of energy, producing gravitational waves, and often resulting in a kilonova: a bright explosion that creates heavy elements like gold and platinum. These mergers are significant for astrophysics, as they provide insights into the universe's evolution and the formation of elements. They can also be detected through both electromagnetic radiation and gravitational waves, allowing scientists to study them across different wavelengths, contributing to our understanding of the cosmos.

Neutron star mergers occur when two neutron stars, incredibly dense remnants of massive stars, orbit and eventually collide. This cataclysmic event releases an immense amount of energy, creating gravitational waves—ripples in spacetime—and often leading to the formation of heavy elements, like gold and platinum. Such mergers are also associated with gamma-ray bursts, extremely bright flashes of radiation. They provide key insights into the universe's behavior, stellar evolution, and the origins of elements. Observations of these events have revolutionized our understanding of cosmic phenomena and the life cycles of stars.
