Astronomers spot exposed inner core of ‘quirky’ star by accident

The exposed core of a massive star has been observed for the first time, a find that was described as purely “chance” by the team that found it by chance.

Although the cores of stars are where the vast majority of stellar energy is generated by the nuclear fusion of hydrogen into helium, they are usually obscured by the bright outer material that envelops them. Stellar cores are exposed only in rare and extremely short-lived circumstances.
