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?

[monmarfori]

Betelgeuse will explode in a supernova in the next thousand years.

[Dan Dixon]

Betelgeuse will explode in a supernova in the next thousand years.

Please be careful about making absolute statements that aren't supported by facts.

"Some astronomers believe it may become a supernova within a timeframe where it could be observable by human civilization."

A better way of saying this would be:
Betelgeuse may supernova in the next thousand years.

Edit:
And how awesome is that. It could supernova tomorrow (~640 years ago), but probably not.
