The Death Star (Supernova close to Earth - could wipe us out)
thesun.co.uk ^ | Jan. 5, 2010 | PAUL SUTHERLAND

Posted on 01/05/2010 5:34:26 PM PST by Free ThinkerNY

A STAR primed to explode in a blast that could wipe out the Earth was revealed by astronomers yesterday.

It will self-destruct in an explosion called a supernova with the force of 20 billion billion billion megatons of TNT.

New studies show the star, called T Pyxidis, is much closer than previously thought at 3,260 light-years away - a short hop in galactic terms.

So the blast from the thermonuclear explosion could strip away our ozone layer that keeps out deadly space radiation. Life on Earth would then be frazzled.

The doomsday scenario was described yesterday by astronomers from Villanova University, Philadelphia, US.

They said the International Ultraviolet Explorer satellite has shown them that T Pyxidis is really two stars, one called a white dwarf that is sucking in gas and steadily growing. When it reaches a critical mass it will blow itself to pieces.

It will become as bright as all the other stars in the galaxy put together and shine like a beacon halfway across the universe.

The experts said the Hubble space telescope has photographed the star gearing up for its big bang with a series of smaller blasts or "burps", called novas.

By God, as long as there is a penny of wealth left to transfer we WILL be safe from this calamity, I just know it!

BS, unless one of the poles are aimed at us, 500 light years is enough distance to be safe from a supernova

I’d feel better if you can elaborate on that. I know certain blasts aim the explosion along a narrow plane, but not all?

So, about 3300 LY away. Assuming a particle stream traveling at somewhat less than the speed of light as the primary destructive agent (if there are any), that gives us a few thousand years to come up with something. So, any ideas? Some kind of Dyson Sphere surrounding the Earth, or significant parts thereof? Maybe a magnetic deflector field to shunt those particles off to the side? I’m sure the techie-trekkies among us can come up with something.

The Crab Nebula is 6500 light years away. It was a supernova that while noticed in the daytime in 1731 it had no ill effects. At 3500 Light years this supernova is still too far to worry about, but it would make for a great show!

Unnhh. Hate to be the bearer of bad news, but the light reaching earth from there is 3200+years old already. By definition it could have exploded in an OMGDIZE explosion 3199 years ago and we could not see it yet, because, the light and explosion from there is still on the way here.

That being said I have other crap to worry about.

3,260 light-years away - a short hop in galactic terms.

Unfortunately, it blew up 3,259 years ago, and we will finally "see" its explosion next November.

Then will come the slower moving pieces.

The Beta Cassiopeia supernova was twice as far, roughly, and nobody on Earth was bothered much, back in 1572, except for the daytime star generating much talk.

Simesis 147 went off about 100KY ago, and was a tad closer, 3000 LY. Didn’t wipe life from Earth. Eyewitness reports are somewhat vague :)

The Vela supernova was 800 LY away! Woo hoo, if we are worried about 3200 ly distance, this one was in our lap! 10,000 BC or so, so there were people around then to take UV readings to measure ozone depletion. No fluorocarbons back then, so the readings would be uncluttered.

Vela Junior may have been closer.

The supernova remnant that’s now the Crab nebula went off 1n 1054, widely observed, and was 7000 ly away.

Supernova 185 was a big hot type 1A at only 3000 ly distance, about the same as the one coming up.

Point is, there have been supernovas in the past, some with people around, some as close as this Doom Star, and we pulled through.

I realize that back in the year 185 we did not have MSM to scare us to death with endless accounts of what the ozone layer is doing. Tune in at 11 to learn the ozone depth over YOUR town and what type of sunblock President Chelsea Clinton uses.

When one looks at a star 3300 LY away, one is looking at the past, 3300 years ago - so whatever process has happened so long ago in this star’s history, we will experience in our world’s future. We may have time to prepare but it is no 3300 years - the radiation (”cosmic” rays) travel quite close to or at the speed of light, and will do what they will do.

Now that, will cause global warming.

Perhaps if we sacrifice Algore to the sun god it won't happen.

It's worth a shot.

For at least 500 years, anyway!

On the other hand, it may have already supernova'd 499 years ago!

We must immediately repeal the ban on CFC's and start a Manhattan Project to produce ozone.

“The doomsday scenario was described yesterday by astronomers from Villanova University, Philadelphia, US.”

Isn’t Villanova a catholic school? Don’t they read the Bible at all? Either this supernova is not going to go off, or it will not do anything like what they are saying. The BOOK says that after the fast-approaching 7 years of Tribulation on this old battered planet, there will be the 1000 year reign of Christ, known as The Millennium.

I think I’ll choose to believe The BOOK rather than some apparently unbelieving backslid eggheads.

The problem is that the “poles” where gamma rays are emitted seem to be aligned with the Earth. The article didn’t really explain this. This close to the Earth, and at strengths of other gamma ray bursts that have been observed, this WOULD be bad.

OTOH, this sort of thing doesn’t seem to have happened to the Earth in a very long time - so why should it happen in the next 50 years?

that gives us a few thousand years to come up with something. So,

Someone unclear with the concept.

The fact that it is 3260 LY away doesn't mean that we already received the email

It could have happened already 3259 years ago,and we would blissfully ignorant.

Doesn't that suck?

Liberals think our world is a perfect place and only man can screw it up. They can not grasp the concept that we live on a violent and volatile planet that’s in a very violent and volatile galaxy. We’re here just for the ride and we can’t stop nothing catastrophic from happening and that includes climate change.

Oops, yes, I forgot my basic relativity. Shows you what being out of the physics business for the last 20 years will do. *blush*

Now, if I can just get that warp drive thingy going, we'd have a little advanced warning. Didn't Beowulf Shaeffer pull a similar trick when he found out the galactic core exploded some 20,000 years prior to his starting out? Gave the inhabitants of Known Space a little heads-up (they weren't too worried, except the Puppeteers). Of course, he survived decapitation and a shot from an ARM punchgun, so he's a bit more resilient than most.
