We may have witnessed a black hole or neutron star being born from a dying star, according to analysis of an unusual rhythmic supernova.

When a star runs out of the fuel it needs for nuclear fusion, it goes supernova and collapses in on itself, falling onto the core and blasting out material in a bright explosion.

Astronomers have evidence linking extremely massive supernovae to the formation of ultra-dense remnants like neutron stars and black holes, collectively called compact objects …
