For the first time, astronomers are confidently predicting that a specific ste
llar system will explode within a defined period of time, becoming more than 1
0,000 times brighter than it is now. The explosion will be visible from Earth
with the naked eye, and it could be about as bright as Polaris, the north star
.

對於會認星座的人來說很容易就能注意到

超新星應該是記者自己寫的吧
