Astroquizzical: What happens when Betelgeuse explodes?
It’s one of the nearest red supergiants to us, and a supernova is only a matter of time. What are we in for when it happens?
Question: If Betelgeuse explodes right now, could we see it with naked eye? It is over 400 light years away, so you might think that people would see it long after it actually happens?
