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
.
专家是推估跟北极星差不多亮
不算太亮但都市里也看得到
对于会认星座的人来说很容易就能注意到
但是文中没有说这是supet nova
跟超新星定义的重量塌缩触发大爆炸不同
超新星应该是记者自己写的吧

两星体碰撞,为何会爆炸?引发核融合吗?能量来源是?
