X-Ray Burst Temporarily Blinds NASA Satellite

RedEaredSlider writes with news that a recently-detected gamma-ray burst, originating roughly five billion light-years away, was powerful enough to temporarily blind NASA's Swift satellite. Phil Plait has an interesting writeup on the event. Quoting: "Swift, normally easily able to handle the X-ray load from these explosions, was overwhelmed, and actually shut down temporarily when software detected that the cameras onboard might get damaged by the flood of light. That’s never happened before. The burst was so bright in X-rays it put other GRBs to shame: slamming Swift with 143,000 X-ray photons per second, it was 5 times brighter than the previous record holder, and nearly 200 times as bright as a typical GRB! Weirdly, it didn’t look out of the ordinary in visible light."

      Technically you may be right, but this is Slashdot, so we need a car analogy:

      5.68E-10 J/S = 5.68E-10 W. The Corvette ZR-1* puts out 476 kW = 476E3W (638 hp). 476E3/5.68E-10 = 8.38028169E14 ~= 838E12

      From Wikipedia's entry on Gamma Ray Bursts [emphasis added]:

      Most observed GRBs are believed to be a narrow beam of intense radiation released during a supernova event, as a rapidly rotating, high-mass star collapses to form a black hole.

      The other probable cause of GRB's, the merger or two neutron stars, would also rotate rapidly as the stars moved in more closely (conservation of angular momentum: think of a figure skater pulling in her arms).

  20. Wonder if we'll see other effects. by meerling · · Score: 1

    Since it was an extraordinary x-ray discharge from a great distance with no other apparent discharges (radio, infrared, visible, etc), I have to wonder if continued observation will eventually yield those at a later time. If so, how would that be interpreted? (Not only regarding the cause/aftermath of the event itself, but also interference by interstellar materials and possible changes to em propagation.)

    I don't know much science, but I know enough to make science teachers nervous ;)

      Plenty of extraordinarily distant GRBs have been observed already and no evidence has been found yet of variation of EM propagation speed across the spectrum over long distances.

  21. Re:Weirdly? by mrsquid0 · · Score: 4, Informative

    It is not unusual for gamma-ray bursts to have X-ray afterglows, but no optical afterglows. About 95% of gamma-ray bursts have X-ray afterglows, but only about 60% have optical or infrared afterglows. The reason is that if there is a clump of dust between us and the gamma-ray burst the X-rays will go through, but the optical light will be scattered and never reach us.

    I wonder if the burst was close enough to LIGO for it to pick up a Gravity Wave? That's the theory anyway that gravity waves should be measurable in association with GRBs... But waves in the ocean travel much slower than the wind that creates them, so maybe there's a lag between the event and the actual measured wave.
