1. Neutron star merger animation ending with kilonova explosion


    from ESO Observatory Added 31 0 0

    This artist’s impression video shows how two tiny but very dense neutron stars merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short…
