This is the post that I was trying to get up on the 4th. Now I’m back to a normal internet connection and life is peachy.
It is now approaching a quarter of a millennium since our founding fathers signed the Declaration of Independence, which is a long time in human years, but not so long in celestial ones. In the year 1006 A.D. a supernova was observed on earth, the remnants of which are shown in detail in this photograph taken by the Hubble Space Telescope, featured as NASA’s picture of the day. At the time it was the second brightest object in the night sky after the moon, and is estimated that the resulting shock wave has traveled at up to 20 million miles an hour over the last 1000 years.
