Betelguese

Post #1by PlutonianEmpire » 28.03.2009, 04:29

Apologies for spamming the forum with questions. :oops:

Anyhoo, when Betelguese goes supernova, is it close enough to affect earth? Also, does it have one of it's poles pointed at us? I ask because I heard if a nearby star goes supernova and has one of it's poles pointed at us, we could be in for a gamma ray burst problem...

You might consider using Google. I've found that answers I search for myself usually stick with me. :)

It's discussed in a Wikipedia article at http://en.wikipedia.org/wiki/Betelgeuse
and in a discussion on BAUT at http://www.bautforum.com/astronomy/3507 ... -info.html

If I recall correctly, Betelgeuse's poles are not directly facing us.

But don't take my word for it... follow Selden's advice. :wink:

There was a map of the surface of Betelgeuse,made by a telescope.I?m not sure if it was an optical image.But it disappeared,the same way as Ceres?map.

A map of Betelgeuse's surface? If I recall, it's been resolved, and that's about it.

Surface imaging of Betelgeuse was done in 2006 (correction, 2000), detecting several hot spots.

It was a very very low resolution of Betelgeuse,but at least is better than the default M texture...the same for Ceres. :)

Yes,but someone DID a map,but this "texture" somehow disappeared,the same way as Ceres map.Is there any way to locate them or is it missing forever.
I?m not sure but I think I could find these in the defunct Nasa download servers... :?

I have an old copy of that betelgeuse telescope view texture on my other computer. If it is really needed, I will dig it up and post it here.

Well, I don't 'require' it, but I wouldn't mind seeing it here.
