Astronomers and
astrophysicists from Harvard-Smithsonian Center for
Astrophysics have revelaed that back on the 27th of
December 2004 there was a an explosion from a type
of neutron star called a magnetar that was so large
it only occurs once every 1000 years. If the
explosion was closer than 10 light years it would
have wiped out the ozone layer leading to major
extinctions.
Yosi Gelfand, who
is an author of one of the many research papers
about this intenese explosion, explained that
"Fortunately, there are no magnetars anywhere near
the earth. An explosion like this within a few
trillion miles could really ruin our day,"
It is thought
that this kind of explosion is similar to a solar
flare except that these stars have such densely
packed surfaces that can sometimes explode so
violently that the gamma rays released can be
destructive for several thousand light years
around.
