we're about to get a new star in our night sky torona Borealis is located about 3,000 Lighty years away but this star system is what's called a recurrent Nova every 80 years the star begins increasing in brightness and then goes through a period of dimming then 11 months later it explodes and becomes much much brighter this brightness lasts for a few days though Peak brightness is only about 12 hours and then the cycle starts all over again so what might cause a star to explode over and over aga
in in this kind of cycle the prevailing theory is that it's because T Corona Borealis is a with a red giant and a white dwarf these two stars are relatively close together that means the dense white dwarf is collecting Mass from the Red Giant star so this pressure builds and builds and builds until eventually the hydrogen explodes unlike a supernova though the whole star isn't destroyed it's just that stolen material from the red giant then the cycle starts all over again scientists think that t
Corona Borealis could explode anytime between now and September it will appear in the corona Borealis constellation which is in the sky between Hercules and botes
