Astronomers spot exploding faraway star

WASHINGTON - A massive exploding faraway star — the brightest supernova astronomers have ever seen — has scientists wondering whether a similar celestial fireworks show may light up the sky much closer to Earth sometime soon.

The discovery, announced Monday by NASA, drew oohs and aahs for months from the handful of astronomers who peered through telescopes to see the fuzzy remnants of the spectacular explosion after it was first spotted last fall.

Using a variety of Earth and space telescopes, astronomers found a giant exploding star that they figure has shined about five times brighter than any of the hundreds of supernovae ever seen before, said discovery team leader Nathan Smith of the University of California at Berkeley. The discovery was first made last September by a graduate student in Texas.

"This one is way above anything else," Smith told The Associated Press. "It's really astonishing."

Smith said the star, SN2006gy, "is a special kind of supernova that has never been seen before." He called the star "freakily massive" at 150 times the mass of the sun.

Observations from the Chandra X-ray telescope helped show that it didn't become a black hole like other supernovae and skipped a stage of star death.

Unlike other exploding stars, which peak at brightness for a couple of weeks at most, this supernova, peaked for 70 days, according to NASA. And it has been shining at levels brighter than other supernovae for several months, Smith said.

And even at 240 million light years away, this star in a distant galaxy does suggest that a similar and relatively nearby star — one 44 quadrillion miles away — might blow in similar fashion any day now or 50,000 years from now, Smith said. It wouldn't threaten Earth, but it would be so bright that people could read by it at night, said University of California at Berkeley astronomer David Pooley. However, it would only be visible to people in the Southern Hemisphere, he said.

Bush’s fault, of course.

“freakily massive”

Michael Moore eat one hot dog too many?

Not something you want to have happen within a few dozen light years.

Note to self: Never ask these guys what time it is.

Is this the explosion that blew away the definition of a "standard candle"?

Essential, two stars collided to exceed the expected maximum mass of a supernova?

Whew, no problemo. This happened 240 million years ago and we're still here.

And this time -- definitely NOT Bush's fault.

Nancy Pelosi and Harry Reid issued a joint statement and called for funding to be pulled from NASA; since us looking caused the explosion. Further “We have to ask ourselves if we are doing more harm than good. Without our interference would the stars just get along”.

Wonder how many Carbon footprints that will cost us.

So naive.

Bush has a time machine and starship.

Blowing up stars is a hobby of his.

It has to be, because it makes it all make sense!

According to Schroedinger, the star simultaneously exploded and didn’t explode, until we looked...then it exploded.
