Would you freak out if I told you that a gammaray explosion migh accur? Dont bother because ot allready did. An amazing cosmic explosion first detected by NASA's great observatory it happened on Christmas day it was caused by either a novel type of supernova located billions of lightyears away or an unusual collision very close to our galaxy. Papers describing both interpretations appear in the Dec. 1 issue of the journal Nature
Gammaray explosions are the universe's most lighted and dangereus explosions, it emitting more energy in a few seconds than our sun will during its entire life. What astronomers are calling this the "Christmas burst" they also state that it is "so unusual that it can be modeled in such radically different ways."
"What the Christmas burst seems to be telling us is that the family of gamma-ray bursts is more diverse than we fully appreciate," said Christina Thoene (the supernova study's lead author) scienctists are rapidly detecting hundreds of them, in some cases the scientists can catch some of them.
What happens is that the crushed core that forms when a star much bigger than the sun's mass explodes. When the star's fuel is exhausted, it destroys under its own weight, pushing on its core so much that about a half million times Earths mass is squeezed into a ball no larger than a city. And then explodes.
Wow. I find these gammaray bursts increadibly interesting they can last about 7 to 8 minutes but can whipe out an enitire galaxy. There is even a 1/13billion chance that it can happen to us this very second. They are amung the most powerfull rays, for this to happen and be seen by scientists is wonderfull and excrusiating.
