Comet ISON still alive & moving at about 200 miles/sec

ISON entering the sun’s outer plasma atmosphere on 27 Nov 2013 as seen by NASA’s SoHo spacecraft.
Reports of Comet ISON’s suicide by sun have been premature. The plucky little nucleus, now thought to be less than a mile across, is streaking closer to its perihelion tomorrow at about 1:37 EDT. The next two days are the time of greatest danger for ISON. If it survives there’s a chance residents in the northern hemisphere will have a clear view of the comet in the first half of December, stretching across as much as a degree or two of arc, as it passes above the earth’s orbital plane at warp speed on its way out of the solar system forever: [Read more...]

The moment of truth approaches for ISON

Thanks to some generous readers yesterday, this will be the last day before Thanksgiving Week I’ll have to bleg for money.

False-color mosaic courtesy of NASA’s Cassini spacecraft shows differences in the composition of surface materials around hydrocarbon lakes at Titan, Saturn’s largest moon. Kraken Mare, which is Titan’s largest sea and covers about the same area as Earth’s Caspian Sea and Lake Superior combined, can be seen spreading out with many tendrils on the upper right. The orange areas are thought to be the Titan equivalent of salt flats on Earth. Click image for more info at National Geographic online.

The mind reels when speculating how creationists and other Old Testament literalists might spin this one. For the rest of us, it’s just fascinating scientific detective work: geo-astronomers have confirmed a healthy sized comet lit Egypt on fire millions of years ago. If they’re right it would have made the 1908 Tungaska Event look like a shoe-bomb: [Read more...]
