View Full Version : A hyper-giant blue?

Pinemartinette: beware spoilers. In the latest disaster Enterprise, Archer and crew find a star within a couple of hundred years of going supernova. Besides the fact that Travis demonstrates his usual, infantile, not-in-a-lifetime-would-this-guy-ever-get-past-the-rank-of-private, type of conduct, could a star like this be blue? Archer says that the circumference is one billion miles/kilometres. I understand that some O class stars are huge. But would any star be blue when on the edge of going supernova?

I take it from your comments that you're not a huge fan. Join the club (http://www.badastronomy.com/phpBB/viewtopic.php?t=3759).

Supernova SN1987a appears to be such a star. A check of previous plates of the region showed a blue star, Sanduleak -69 202, at the location of the supernova. That was quite a shocker back then, because consensus up to that point had been that only red supergiants went supernova.

Edited to correct the name of the precursor star. I really should spend more time looking at the rest of the Bad Astronomy site!

Yes. But was there not some kind of reason? A companon star which exploded? To what I know, the stellar cartography of that region was, at best, somewhat limited.

What I wanna know is, what did Archer mean by a "hypergiant"? Is a hypergiant to a supergiant what a hypernova is to a supernova?

Liar, that is all fake! I've seen pictures that show it was made on a computer! :lol: That, and the shadows are all wrong. :P

If this were really true, wouldn't we see orbital purturbations of Planet X from rhw gravatational effects? Would there still be Moon hoax believers? Impossible!!!! ;) :D :roll: :lol:
