Repeating supernova challenges all we know about stellar death

At the end of its life, a star goes supernova, ejecting its outer layers in one of the biggest cosmic cataclysms in the universe. With most of its mass gone the star then “dies”, collapsing in on itself to form a black hole or a neutron star. Thousands of these events have been observed over decades, but now one star has broken the rules and refused to die, somehow exploding several times over 60 years. The find may challenge everything we know about the death of stars.

Eta Carina is famous as a supernova imposter. Like a few other stars it survived its supernova virtually unscathed.

I personally think that supernova imposters are quite common among the most massive stars, as they prepare themselves by shedding outer layers getting ready for the final kaboom.

Maybe someone is tampering with the process
