I swear, I need to trust my instincts. As soon as I saw the article on the news.com.au site desperately trying to link Betelgeuse going supernova with the nonsense about the Mayans and 2012, my gut reaction was to write about it.
But no, I figured a minute later, this story would blow over. So to speak.
I should’ve known: instead of going away, it gets picked up by that bastion of antiscience, The Huffington Post.
Grrrr.
The actual science in the original article is pretty good; they talked with scientist Brad Carter who discusses the scenario of Betelgeuse going supernova. The whole story is pretty interesting — I wrote about it in detail the last time there was nonsense about Betelgeuse blowing up — but in a nutshell Betelgeuse is a red supergiant star in Orion with about 20 times the mass of the Sun, and it’s very near the end of its life. When stars this massive die, they explode as supernovae. The distance to Betelgeuse is unclear (it has a very puffy outer atmosphere which makes distance determination somewhat dicey) but it’s something like a bit more than 600 light years, way way too far away to hurt us.
It’s the question of when that the two articles go off the rails. Betelgeuse may explode tomorrow night, or it may not go kerblooie until the year 100,000 A.D. We don’t know. But given that huge range, the odds of it blowing up next year are pretty slim. And clearly, the original article was really trying to tie in the 2012 date to this, even when it has nothing to do with anything. The tie-in was a rickety link to scuttlebutt on the web about it, but that’s about it.
What’s worse, the HuffPo article attributes the date to Dr. Carter himself, but in the original article he never says anything about it; the connection is all made by the article author. Given how popular HuffPo is, I imagine a lot of people will now think an actual scientist is saying Betelgeuse will blow up in 2012.
OK then, tell you what: I’m an actual scientist, and I would give the odds of Betelgeuse going supernova in 2012 at all — let alone close to December, the supposed doomsdate — as many thousands to one against. It’s not impossible, it’s just really really really really really really really unlikely.
Really.

It’s been a while since I’ve done a good ol’ smackdown debunking, so let’s take these one at a time. First things first: the spaceships. Shown here, as you can see, the article refers to a picture of a big blue wormy-thingy floating in space. What could it be? Well, because I don’t trust articles online talking about giant spaceships invading us (or anything anyone says about doomsday in 2012), I went to the original pictures themselves. 
I did an interview with reporter Maria Sciullo of the Pittsburgh Post-Gazette a few days ago, and
