I read an article yeasterday in the Astronomy magazine. It's A1689-zD1 we see it as about 3Gly distant but, the light is like from 13Gly, but is currently at 30Gly.
A1689-zD1 at 30Gly
Now... Betelguese is gonna blow soon! How bright will it be (magnitude or reference object)? And can it blind you if look at it?
