[Blunderov] Gamma rays are of the very shortest, most energetic
wavelengths. They are used in radiation therapy for cancer and are very
harmful to tissue. The energy levels involved in this recent event are
mind-numbing. Possibly the star was stimulated by x-rays somehow?

Dr. Rob Fender of Southampton University is a co-author on a Nature
paper describing the radio observations.
"This is a once-in-a-lifetime event. We have observed an object only 20
kilometres across, on the other side of our Galaxy, releasing more
energy in a tenth of a second than the Sun emits in 100,000 years," said
Fender.
"The next biggest flare ever seen from any soft gamma repeater was
peanuts compared to this incredible December 27 event," said Dr. Bryan
Gaensler of the Harvard-Smithsonian Center for Astrophysics, lead author
on the Nature paper.
"Had this happened within 10 light years of us, it would have severely
damaged our atmosphere and possibly have triggered a mass extinction.

Scientists have known for many years that the nuclei of some elements,
such as hafnium, can exist in a high-energy state, or nuclear isomer,
that slowly decays to a low-energy state by emitting gamma rays. For
example, hafnium-178m2, the excited, isomeric form of hafnium-178, has a
half-life of 31 years.
The possibility that this process could be explosive was discovered when
Carl Collins and colleagues at the University of Texas at Dallas
demonstrated that they could artificially trigger the decay of the
hafnium isomer by bombarding it with low-energy X-rays (New Scientist
print edition, 3 July 1999). The experiment released 60 times as much
energy as was put in, and in theory a much greater energy release could
be achieved. </snip>
