A new star is about to light up, but it will shine for a few days. T Coronae Borealis explodes every 80 years, it will become as bright as the North Star.
The explosion occurs when the gas reaches a critical temperature. “This could be a once-in-a-lifetime opportunity,” NASA said in a statement. The pair of stars is located about 3,000 light-years from Earth within the Corona Borealis, a small constellation in the Northern Hemisphere.
