First Evidence of Supernovae Found In Ice Cores
KentuckyFC writes "Supernovae in our part of the Milky Way ought to have a significant impact on the atmosphere. In particular, the intense gamma-ray burst would ionize oxygen and nitrogen in the mid to upper atmosphere, increasing the levels of nitrogen oxide there by an order of magnitude or so. Now a team of Japanese researchers has found the first evidence of a supernova's impact on the atmosphere in an ice core taken from Dome Fuji in Antarctica. The team examined ice that was laid down in the 11th century and found three nitrogen oxide spikes, two of which correspond to well known supernovae: one event in 1006 AD and another in 1054 AD, which was the birth of the Crab Nebula (abstract). Both were widely reported by Chinese and Arabic astronomers at the time. The third spike is unexplained, but the team suggests it may have been caused by a supernova visible only from the southern hemisphere or one that was obscured by interstellar dust."
It's still gay.
1054 AD, which was the birth of the Crab Nebula
The Crab Nebula is 6,500 light years away from earth (http://en.wikipedia.org/wiki/Crab_Nebula).
This means the birth of the Crab Nebula was in the year 5446 BC. Mankind witnessed it 6,500 years later.
News stories on such phenomena invariably leave out this little fact, i.e., that which is witnessed by man in the sky usually happened thousands of years earlier than when he actually saw it. This makes it confusing for the average reader.

Only a matter of time until they find an actual frozen supernova in the ice.
...It seems the third spike (assuming I am reading the graph correctly) occurred around 1060-1080AD.
Shit happens and it's usually caused by assholes
ha! am reading this book atm... http://en.wikipedia.org/wiki/Dies_the_Fire :-P
Made me think for a moment
"Consider how lucky you are that life has been good to you so far. Alternatively, if life hasn't been good to you so far
clearly this is a conspiracy by oil companies to prove global warming isn't man made.
If you mod me down, I will become more powerful than you can imagine....

It would be interesting to see if they can extrapolate general weather patterns for the 50 years following these 2 (or 3) supernova. Maybe this will give us a definitive answer on whether or not they can impact our weather and by how much.
Hmm... "birth of the Crab Nebula" or "death of the Great Crab Civilization"?
You decide.
The Japanese novel Tale of Genji was supposedly written between 1008 and 1021 A.D.
It's been decades since I've read it... I wonder if there's any reference in there to smog around Mt. Fuji?
A bit further west, the Battle of Hastings was fought in 1066 A.D.
It's four thirty a.m. and the house is asleep.
I. . . am not asleep.
I am crouched in the bathtub in a frog-like stance, small puddles of urine and liquid shit at my feet. I'm leaning forward, gripping the side of the tub and biting my knee, overwhelmed by a mixture of pain and pleasure as I piston a dildo in and out of my ass.
You see, I really love anal masturbation.
Ever try it? No? You should.
Doesn't matter who you are. God gave all of us, male and female, an abundance of nerve endings in our rectum - and one life to live. So why don't you go ahead and test out the equipment? Have some fun. No point in having a gun sitting on your shelf your entire life and never killing anyone, right?
But I realize there's a fairly persistent misconception among guys that I'm gonna have to dispel before we go any further:
Stimulating your own ass is not "gay."
That notion doesn't make a whole lot of sense. I mean, how could anything you do to your own body be gay? Nobody ever freaks out in the middle of jerking off like "Holy fuck, I've got a fistful of cock! I've gotta cut this gay shit out!" Well, what's the philosophical difference between playing with your dick and playing with your ass?
There is none.
Look fellas, here's the scoop:
If you have a girl wearing a foot long strap-on, smacking your face and screaming "WHO'S MY BITCH?!?" while she pounds your asshole until it bleeds, that would be a *heterosexual* act. Girl on guy. Simple.
Now if it's a guy that's fucking you, that would be homosexual. And if you're doing it to yourself, well, that's plain old masturbation.
But listen - if you're still sitting there being stubborn, all macho and uptight going "My ass. . . is EXIT ONLY!!!" then lemme just ask you a question.
You know that feeling you get when you take a really big shit?
You know what I'm talking about. You're sitting on the couch, eating Cheez-Its and watching Larry King, when all of the sudden you feel that familiar burning. . . so you get up and bound off to the bathroom all bow legged, clenching your sphincter real tight, and then you furiously rip off your boxer briefs and plop down on the seat just in time to let a huuuuuuge thick turd come sliding out of your ass?
Ahhhhhhhhh!!!!
That feeling.
That tingling, chills up your spine, this-is-absolutely-the-pinnacle-of-human-existence feeling.
Well guess what. That's the feeling of a massive rod moving through your rectum, tickling those wonderfully abundant nerve endings. You love it. It's okay. We all do. It doesn't make you a fag. Or at the very least, we're ALL fags. So indulge yourself.
(Yes, I understand that said feeling is partially due to the sensory experience of toxins leaving the body, which is unique to defecation - but the operative word here is "partially." You like the log movement, too. Don't try to argue.)
So anyway, now that you've decided to be bold, and not a homophobic pussy, and poke around the cornhole a little bit - good for you. But there's something you should remember. Anal masturbation is just like playing the accordion, or shooting a jumper, or really anything else that's worth doing. That is, it requires practice.
You see, back when I was a kid I would get curious and stick a finger or a toothbrush up there, but I wasn't fucking around with anywhere near the kind of pleasure I'm achieving now. It was uncomfortable even. So I worked on it.
And conversely, I know I'm still far from expertise in this particular discipline. I don't claim to be an ass master. There's a whole world of lengths, girths, textures, and vibrations that my eager browneye has yet to inhale.
But since I have honed my skills to a pretty decent level, I'll share with you my current technique. Without further ado:
SpunkyBrewster's Anal Masturbation Technique
What You Need:
1. Lubricant of your choice
2. Fake cock (eight inches, approx.)
3. Ridged anal wand (seven inches, approx.)
Procedure:
How do they know that the spike wasn't cause by some Connecticut Yankee's magic, hmmm?
Look at the image in the article:

If these really are the supernovae, doesn't this mean that "model B" is right and "model A" is wrong?
I want to know if there was a supernova around the year 0 that would have been visible from the middle east...
I've abandoned my search for truth; now I'm just looking for some useful delusions.
your sig is truncated. try checking it out after you save a new one. that is all.
The Crab system civilization turns on it's first Large Hadron Collider......
After logging in slashdot still does not take you back to the page you were on. It's been that way for 20 years.
If they find a nova in the ice, it may very well be a pretty darn good nova. But a super nova? Unlikely.
mod parent down; parent is a global warming denier.
The crab nebula is 6500 light years away. The SN1006 event was 7200 light years away. The Betelgeuse supernova could appear to earthlings at any moment, and it's only 640 light years away.
Forgive me for the attention-seeking headline, but I've read very interesting things about Antarctica and its ice sheets.
Primarily, there were maps made in the 1500's that closely resemble an ice-free Antarctica. They document mountains we've detected in the 1900's by sonar, and reflect the Antarctic coastline closely.
If these maps are correct, and there was no ice in the 1500's... how were these ice cores found?
If the ice cores were found, and they date back to 1000 AD, how were these maps made with knowledge of Antarctica having no ice?
I'm very curious. One good article I found is here:
http://www.diegocuoghi.it/Piri_Reis/PiriReis_Hoye-Lunde.htm
Quite plausibly, it seems that the maps are, in fact, not maps of Antarctica. I wonder how that affects the arguments given... thoughts?
We get transmission, main screen turn on.
There's nothing particularly funny about the above correct statement.
I really can't believe people are having such a hard time grasping the consequences of "no absolute time."
(founded 95,000,000 yrs ago, very space opera)
I think one important fact here is that scientists can measure the effect on the atmosphere of an event that happened a thousand years ago. Would it be reasonable to assume that they couldn't measure the effects of what's happening right now?
Yes, the sun variations influence climate. But human emission of gases into the atmosphere also influence climate, and scientists have means to determine the amount of influence due to each effect.
Why peculiar? That's exactly what I would expect. As snow gets piled higher, there will come a point when the weight from the accumulated snow is more than the strength of snow crystals can support. At the crystals get crushed, the structure will change from a porous mass of snow crystals to solid ice with some bubbles of gas.
This shift from snow to ice will happen quickly, because as a snow crystal breaks the weight it supported will shift to nearby crystals, increasing the stress on them. It could well be that the shift from porous to solid ice happens in a short period of time and, depending on average amount of snowfall, this could take tens of years of accumulated snow to happen.
There are maps from the 1500s that show california as an island.
Those are maps from the FUTURE, when the ice caps have melted and Los Angeles is Arizona Bay.
I think they have a somewhat interesting theory, but this data hardly proves anything. They have 3 spikes and only have 2 known known supernovas. They do not know the source of the third spike; they only have guesses. While their explanation seems plausible, I am not going to place a lot of faith in a theory that only has working evidence 2/3 of the time and the researchers must use unscientific guesses 1/3 of the time to maintain their theories.
Actually what this means is that those who think the logic in parent post is valid need to bone up on relativity and light cones.
This did not happen in 1054. I am well-aware of relativity smartass, and that has nothing to do with the simple historical fact that it happened 6,500 years before mankind experienced it.
Point out a different way of looking at things, get a nerd syntax error.
