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 !

However, just to be safe, I think we should implement all of Al Gore's global warming policies. You just never know.

I have faith that some highly advanced civilization in our galaxy will fly to it and do something to save themselves, ultimately saving us as well.

...perhaps plant an explosive on the surface, heroically sacrificing themselves for the greater good, while Aerosmith plays in the background....

So, essentially, like Matt Cassel. Got it.

If it was aimed right at us, the advanced alien civilization would probably shrug their shoulders and not care, unless they knew we existed and cared about us.

A gamma ray burst from a dying star is like a gun (except it would shoot in 2 directions, forward and backward, instead of just forward). This hypothetical alien civilization would be standing off to the side seeing the gun pointed away from them, maybe not knowing or caring that we were in the crosshairs.

Here's what they are talking about. If you are in one of those two beams of light, bad news for you. More than likely we wont ever be though, unless we are incredibly unlucky.

Energy/power levels that are impossible to comprehend. The numbers stagger the imagination.
