Betelguese supernova

    Is there anyway we can determine if Betelgeuse has gone supernova earlier this month? (theoretically speaking)

    Nope. Betelgeuse is about 600 light-years away. As no information can arrive faster than the speed of light, anything we know about Betelgeuse is 600 years in the past. If something happenned to it in the past month, we wouldn't know for another 600 years.
