    Not to be Peter Picky, but people much smarter than us on Astronomy Picture of the Day say that first photo isn't a Perseid meteor.

    "But the meteor flashing above Discovery is not likely to be one of the Perseids because its path doesn't point back to that shower's radiant."

    This was the first year I actually remembered to watch it and had clear weather. Nice photographs, I'm impressed that people are fast enough to capture it.

    Oh and nice photo from Halifax. Maritimes represent.

    @Gilese: husband and I stayed up late to stand on the hill behind the house and see them. No luck. *sniff* But hey, the geminids are supposed to be awesome, with different colors.

    That's a crappy explanation for Clovis. I don't think archaeological evidence supports that at all.

    I watched a PBS special about this theory. and they demonstrated how an impact crater wouldn't be found. Many times comets themselves are pieces of rock, gas, and ice..instead of one large whole piece of rock. So if one were to enter the atmosphere, it wouldn't be like an asteroid that would leave a large crater. instead it would be like tossing pea gravel onto sand, but obviously on a much larger scale. Thus leaving many shallow craters that could easily fill with sediment over time.

    As I was reading the story one of my first thoughts was "I can’t wait to make some kind of 2001/2010 reference in the comments"

    Apparently I was beaten to it. By everyone.

    I know Jupiter is H-U-G-E but it's still somewhat frightening that it can be hit by something big enough to leave a dent that size and we don't realize it's coming till after the fact.

    Apparently, it's been confirmed as an impact mark by Glenn Orton over at JPL, who's observing the spot using NASA's IR Telescope.

    @Qev: Yup, That Guy below mentioned JPL's confirmation as well. The Austrailian gets no props from them, figures.
    Funny thing, exactly 15 years ago Shoemaker-Levy 9 smacked Jupiter with it's infamous "string-of-pearls" between the 16th and the 22nd of July.

    All these worlds are yours, except Europa. Attempt no landings there. (It's only a few years early.)

    JPL's saying it's an impact. Also, that it's "full of stars."
