Potentially lethal gamma-ray burst from star WR 104 could reach earth
Published May 28, 2013

Earth may lie in the path of a dangerous gamma-ray burst that could wipe out a quarter of our atmospheric ozone.

Astronomers say WR 104, a Wolf-Rayet star about 8,000 light years away, could go supernova any day, which would generate gamma-rays that could reach earth.

'You would first notice a 10-second blue flash in the upper atmosphere, but then the damage would be done.'
- University of Kansas physicist Adrian Melott

"We could see it go supernova anywhere from tomorrow to 500,000 years from now," astronomer Grant Hill told Forbes. "For all intents and purposes, the gamma-ray burst and optical photons from the supernova would arrive simultaneously."Gamma-ray bursts are triggered by supernovae, or exploding stars.

There has been much debate over whether a gamma-ray burst from WR 104 would reach earth, but Dr Hill said it depended on the star's rotation.

"If you look at WR 104 and the image of its pinwheel, it really is a visceral and powerful argument that the thing is face on with an inclination of zero," Dr Hill said. This would mean earth was directly in the line of fire from the star.

University of Kansas physicist Adrian Melott told Forbes such a gamma-ray burst would cause a 50 percent increase in UVB radiation.
"You would first notice a 10-second blue flash in the upper atmosphere, but then the damage would be done," he said.

WR 104 was discovered by University of Sydney astronomer Peter Tuthill in 1998.

We are gonna be totally toasted . I wouldn't plan on it happening in 500,000 years . You should go underground NOW !

Seriously. It leaves you in awe just thinking about it. The most powerful one we've managed to study released more energy than 9000 supernovae exploding all at once. Truly incomprehensible. And on top of that, all that energy is concentrated and collimated into a narrow cosmic laser beam travelling at 99.999999% the speed of light. The light from a GRB can be seen 7.5 billion light years away. Half way across the entire known universe.

Mind blown......

Amazing. My brain can't process this.

It took us 13 years to reach Saturn with a probe. On the cosmic scale it is like traveling millimeters when the nearest star is miles away.

It only takes one year to reach Uranus with a probe. At least once you reach the age of 45 or so.

Don't believe any part of it.

Justification for a current and/or future grants.

No, don't be silly. That's not how it works. Scientists can't just dream up shit for funding. The process is way way too complicated for that. If you had any idea how hard it is to get a grant, you would realize how foolish that sounds.

You a fool if you don't think I'm dead on right.

In the 70's the prediction was we would freeze to death and be out oil by now.
Now we are going to burn up with global warming. This rouge is about to run it's course. So let's try space is going to zap us to death.

All about the $$$$$$ grab.

OK then. I guess I a fool.

They already have a Grant. He's the guy talking. Doesn't anyone pay attention anymore?

Boar # 74 bursted one hellof a gamma ray today. I think I'll get 25 sows bred off that burst. He's a Duroc ya know !

You should give them names based on their production.

Boar # 74 could be The Drowner.
