Watkins and his team wanted to measure the relative movement of galaxies using a different dataset, a catalog of Type 1a supernova.
The ultimate fate of the star is most likely a Type II supernova.
This can lead to runaway thermonuclear reactions and the massive explosion of the star in a Type I supernova.
In all likelihood, it will end its life as a Type II supernova.
A Type II supernova is believed to involve only one immense star in its final state of collapse.
