Current Event= The Explosion in the Sky


On February Twentieth the Swift Burst Alert Telescope picked up that there was a gamma ray burst at 2:12 am. That was the second burst that was picked up around that time. This burst was visible to the naked eye, which is very unusual. The gamma ray explosions' name is GRB 080319B. Scientist said that there were brilliant afterglows. It's said that these after glows were 2.5million times better than the afterglows of the most luminous supernova ever. In Chile the Very Large Telescope and Hobby-Eberly Telescope in Texas a measured the bursts' red shift. The red shift was 0.94 which translates to a distance of 7.5 light years. That means that this explosion took place 7.5 billion years ago. The reasons why we could see the burst with the naked eye was because scientists say it was directed at Earth. Reasons that scientists think it was so big was because its mass, its spin, or magnetic field of the progenitor star. I think that this would be a once in a life time opportunity to view this. I also think that GRB 080319B was something that was in the right place in the right time. This is a magnificent natural space occurrence.
