Tycho's Supernova
blamanj writes "Over 400 years ago, a supernova was visible in Nothern Europe. Astronomer Tycho Brahe helped bring about the collapse of the Ptolemaic system by showing that the 'new star' was not a local phenomena like a comet, but actually existed in (supposedly) unchanging heavens. The star that went nova was part of a binary system, and the supernova explosion sent the companion star shooting off into space. Now, that companion star has been found."
And all this time I thought Tycho Brahe was the co-founder of Penny Arcade!
Astronomist and cartoonist... a true Renaissance man.
Suprnova. There, I've said it :)
I really hate when "Intelligent Design" advocates pop up in threads like this only to tell that Supernovas are too old and complex to evolve in 6000 years so they must have been 'intelligently designed'.
Please. I find that such distrust in the machinations of Nature itself shows us how narrow minded these "scientists" are. "I can't understand it, so God must have done it," essentially. This does not open the door to further research and understanding. On the contrary it closes the door because there is nothing more to be understood beyond "God did it".
Nature is a truly amazing thing. Evolution, Physics, Gravitation, the Stars, the Cells, everything is absolutely beautiful. Why the need to spoil Gaia with your imaginary friend?
you just mentioned it, so ... sack yourself, buddy!
mods: sack him!
lets see Bruce Willis handle an incoming star, don't think you'll be landing on it and drilling a hole to drop a nuke into. Suddenly an asteroid passing nearby doesn't seem quite so bad

Hmmm. Seems to be the day for supernova news. This report says Germain scientists are investigating the possibility that a (relatively) nearby supernova affected earth's climate in a way favorable to human evolution.
And if any of them had life, one better not think what would have happenned to it...
Radiation from the supernova would have wiped any local planets clean of life, and the planets of stellar systems within a dozen light years or so...
A god being bound to physical laws? This allows a non-physical entity the ability to do nothing. Certainly not create energy or matter, or even gently nudge atoms togethor to start life. It just ain't happening.
"Before closing your mind, try opening it a little wider."
Personally, I used to be very open-minded and spiritual. You bet I believed in God.
Now I find beauty and truth, blah blah blah everywhere, without god, and I'm certainly no worse off for it. So been there, done that, it didn't stick.
What is there to say that invisble pink unicorns don't exist somewhere in the universe?
They wouldn't be pink if they were invisible!
I really have to critize The Register. How can there be an article about astronomy without a single picture ? How can there be any scientific article without a picture ? They don't even cite correctly or give a link to a site where you can get further information, either the site of the original scientists or at least the site where one can find the article (which is, btw, P. Ruiz-Lapuente et al., Nature vol431, p.1069). Amateurs!
Here are some _usable_ information: page of University of Barcelona.
And some pictures can be found here (scroll down two pages), there is even a download link for the full paper preprint!
So many spelling mistakes on this site. Spellchecker training anyone?
