Wow -- A Thousand Year Old Supernova Shock Wave

Around May 1, 1006 A.D., observers from Africa to Europe to the Far East witnessed and recorded the arrival of light from what is now called SN 1006, a tremendous supernova explosion caused by the final death throes of a white dwarf star nearly 7,000 light-years away. The supernova was probably the brightest star ever seen by humans, and surpassed Venus as the brightest object in the night time sky, only to be surpassed by the moon. It was visible even during the day for weeks, and remained visible to the naked eye for at least two and a half years before fading away.

It wasn’t until the mid-1960s that radio astronomers first detected a nearly circular ring of material at the recorded position of the supernova. The ring was almost 30 arcminutes across, the same angular diameter as the full moon. The size of the remnant implied that the blast wave from the supernova had expanded at nearly 20 million miles per hour over the nearly 1,000 years since the explosion occurred.

Today, SN 1006 has a diameter of nearly 60 light-years, and it is still expanding at roughly 6 million miles per hour. Even at this tremendous speed, however, it takes observations typically separated by years to see significant outward motion of the shock wave against the grid of background stars. In the Hubble image as displayed, the supernova would have occurred far off the lower right corner of the image, and the motion would be toward the upper left.

Wait, I Pay HOW MUCH In Gas Taxes?

Earlier I had posted a summary of the gas taxes here in Illinois, well here is a handy chart of the prices state by state.

Click for larger image.

Keep this in mind as your planning your vacations this summer.  Oh and remember that local taxes may apply, for example while this lists Illinois as 66.5 cents the same gas in Chicago would have taxes of 82 cents.

Classic Restored -- 'Metropolis' Missing Scenes Found

The museum director from Buenos Aires had something special in her luggage: a copy of a long version of Fritz Lang’s Metropolis, including scenes believed lost for almost 80 years. After examining the film the three experts are certain: The find from Buenos Aires is a real treasure, a worldwide sensation. Metropolis, the most important silent film in German history, can from this day on be considered to have been rediscovered. ...

They (Paramount) oversimplified the plot, even cutting key scenes. The original version could only be seen in Berlin until May 1927 – from then on it was considered to have been lost forever. Those recently viewing a restored version of the film first read the following insert: “More than a quarter of the film is believed to be lost forever.” Zeit Online
This is fabulous news for what has remained a lasting gem of film.  Here is ten minutes from the transformation scene:

Giorgio Moroder did a restoration that colored the slides and added contemporary music in 1984.  I know some hated the tampering but I loved the version and the new interest in the film.  Here is one song from that restoration:
