    Here is one blog that Code Project members should love; Bad Astronomy[^]. That post on magnetars is frankly mind blowing. That something 50,000 light years away can, and did, physically effect Earth. :wtf:

    cheers, Paul M. Watson.

          A recent article in either Astronomy or Sky and Telescope indicated that astronomers expect to find a decent number of variable magentars with new survey satellites.

                  Paul, There's always some kind of Universal disaster happening that could shred our piss ant little blue speck of a planet to star dust, but fortunately, its all been too distant, or not properly aligned. I believe there was another recent event, much like the Magnetar energy release, that could have cause some serious problems on Earth; I originally thought it was a Gamma Ray Burst that, had Earth been in direct alignment, well ... that day would have sucked ... but now I'm not sure it was a Gamma Ray Burst, might have been something else (tried to find Phil's blog entry on it, but I can't). - I'm going to send him an Email and ask, because now it's making me crazy. If you want to get an idea as to what it would take to destory Earth, there's a website dedicated it: http://qntm.org/?destroy[^] And BTW - Earth has been destroyed a total of 1 times thus far (see the website for details). [edit] Ok, I found the blog entry on the other event that happened, you can read about it here: Gamma Ray Burst[^]

                    We might get lucky enough to see Betelgeuse go NOVA from only hundreds of light years away too. They're still iffy about the whole thing though. I'm waiting to see the next update on that one.

                      Baring major advances in stellar evolution modeling, I suspect the first warning we'll see is it going boom. Fortunately, unless it zaps us with a GRB it's too far away to cause any major problems (and it shouldn't because its spin axis is pointed away from us). The current best of our models at the end of the stars life can be summed up as "because it changes fuel types very rapidly stuff on the surface should also change very rapidly". Recent data indicates a 15% shrink in radius in the last 15 years, which is rapid change, but one of the earlier fuel changes with a timescale of hundreds or thousands of years before the next one would also significantly change the core energy dynamics and resulting surface activity (once).

                        I once read a book about creatures that lived on one of these, the neutron star was passing close to the solar system and it was investigated by humans. The book was written from the POV of the creatures, fascinating book just can't remember the title.
