NASA Reveals Extinction Event

(Never A Straight Answer?) However the research is rather solid in this article
About once a day, something remarkable happens: the sky is lit up by a brilliant flash of energy. For a fleeting few seconds, this mysterious burst – coming from a seemingly random direction, different every time – ranks among the brightest objects in the sky.
Among the first 500 gamma-ray bursts detected by Swift is GRB 090429B, currently the farthest explosion ever detected and a candidate for the most distant object in the universe. GRB 090429B hit the Earth directly, but was too distant to have a noticeable effect. However in the distant past, this was not the case theorize some scientists. And in the future, it could happen again, without notice or warning, to devastating effect for all of life on Earth.
Wonder if it was that bright white flash I experienced in the evening a couple nights ago...
NASA'S Swift Catches 500th Gamma-ray Burst

Scientists at NASA and the University of Kansas say that a mass extinction on Earth hundreds of millions of years ago could have been triggered by a star explosion called a gamma-ray burst. The scientists do not have direct evidence that such a burst activated the ancient extinction. The strength of their work is their atmospheric modeling — essentially a “what if” scenario.

The scientists calculated that gamma-ray radiation from a relatively nearby star explosion, hitting the Earth for only ten seconds, could deplete up to half of the atmosphere’s protective ozone layer. Recovery could take at least five years. With the ozone layer damaged, ultraviolet radiation from the Sun could kill much of the life on land and near the surface of oceans and lakes, and disrupt the food chain.
Gamma-ray bursts longer than two seconds are caused by the collapse of a rapidly rotating massive star at the end of its life. As the star collapses, jets of parti-cles and gamma radiation produced by a newborn black hole blast in opposite directions from the stellar core. Scientists think the Earth was hit square on by the jet produced by a gamma ray burst such as shown here.

Yet few have ever witnessed such a flash directly: the energy comes almost entirely in the form of gamma rays, which human eyes cannot detect. Even if our eyes were sensitive to this extremely energetic form of radiation, gamma rays cannot penetrate the atmosphere. Only via orbiting satellites do we know of the presence of these mysterious blasts.
Gamma-ray bursts, or GRBs, represent the most powerful explosions of energy in the cosmos since the Big Bang itself, corresponding to the equivalent of a thousand Earths vaporized into pure energy in a matter of seconds. One of the most enduring mysteries of the universe since their discovery in the 1960s, only recently have they begun to reveal their secrets.
Scientists say that a ten-second burst of gamma rays from a massive star explosion within 6,000 light years from Earth could have triggered a mass extinction hundreds of millions of years ago. In this artist’s conception we see the gamma rays hitting the Earth’s atmosphere. (The expanding shell is pictured as blue, but gamma rays are actually invisible.) The gamma rays initiate changes in the atmosphere that deplete ozone and create a brown smog of NO2.

With the ozone layer damaged for up to five years, harmful ultraviolet radiation from the Sun would kill smaller life-forms and disrupt the food chain. Scientists say that a gamma-ray burst might have caused the Ordovician extinction 450 million years ago, some 200 million years before dinosaurs.
Gamma-ray bursts in our Milky Way galaxy are indeed rare, but the scientists estimate that at least one nearby likely hit the Earth in the past billion years. Life on Earth is thought to have appeared at least 3.5 billion years ago. This research, supported by a NASA Astrobiology grant, represents a thorough analysis of the “mass extinction” hypothesis first announced by members of this science team in September 2003.
“A gamma-ray burst originating within 6,000 light years from Earth would have a devastating effect on life,” said Dr. Adrian Melott of the Department of Physics and Astronomy at the University of Kansas. “We don’t know exactly when one came, but we’re rather sure it did come — and left its mark. What’s most surprising is that just a 10-second burst can cause years of devastating ozone damage.”
Gamma-ray bursts are the most powerful explosions known in the Universe, and most originate in distant galaxies. A large percentage of bursts likely arise from the explosion of stars over 15 times more massive than our Sun. Scientists say burst from a nearby star could cause severe damage to the Earth’s protective ozone layer. In this artists conception we see the gamma rays hitting the Earth’s atmosphere. (The expanding shell is pictured as blue, but gamma rays are actually invisible.)
Explosions In Space May Have Initiated Ancient Extinctions On Earth

A scientific paper describing this finding appears in Astrophysical Journal Letters. The lead author is Brian Thomas, a Ph.D. candidate at University of Kansas whom Melott advises.
Gamma-ray bursts are the most powerful explosions known. Most originate in distant galaxies, and a large percentage likely arise from explosions of stars over 15 times more massive than our Sun. A burst creates two oppositely-directed beams of gamma rays that race off into space.
Thomas says that a gamma-ray burst may have caused the Ordovician extinction 450 million years ago, killing 60 percent of all marine invertebrates. Life was largely confined to the sea, although there is evidence of primitive land plants during this period.
In the new work, the team used detailed computer models to calculate the effects of a nearby gamma-ray burst on the atmosphere and the consequences for life.
Thomas, with Dr. Charles Jackman of NASA’s Goddard Space Flight Center in Greenbelt, Md., calculated the effect of a nearby gamma-ray burst on the Earth’s atmosphere. Gamma rays, a high-energy form of light, can break molecular nitrogen (N2) into nitrogen atoms, which react with molecular oxygen (O2) to form nitric oxide (NO). NO will destroy ozone (O3) and produce nitrogen dioxide (NO2). NO2 will then react with atomic oxygen to reform NO. More NO means more ozone destruction. Computer models show that up to half the ozone layer is destroyed within weeks. Five years on, at least 10 percent is still destroyed.
Next Thomas and fellow student Daniel Hogan, an undergraduate, calculated the effect of ultraviolet radiation on life. Deep-sea creatures living several feet below water would be protected. Surface-dwelling plankton and other life near the surface, however, would not survive. Plankton is the foundation of the marine food chain.
