Incredible, flying Christmas tree caught on video over Sacramento, CA

ABC affiliate News10 in Sacramento had their chopper in the air to cover high school football and ended up capturing something far more interesting. (Yes, I suppose if high school football is your basis for comparison, accidentally leaving on the lens cap would yield hair-raising footage.) If you click to watch the video to the right of the story, you'll see a dazzling object that looks like something from Clark Griswald's front yard holiday display whizzing through the air as the news chopper pursues.

Diamond-shaped objects over Austin, TX

The Austin Planetarium is looking into frequent, recent UFO sightings captured on video by local man Carl Lancaster. The Fox 7 news story is available on YouTube, made available by UFO Blog with the uncut UFO footage added to the end of the video.

In other UFO news, British paper The Sunday Mercury reports that a police helicopter had a rather harrowing encounter with a UFO over Birmingham.

Strange aurora over Saturn's north pole

The Cassini spacecraft - while intrepidly carrying out its mission of pointing a camera at Saturn and its moons from as many angles as possible, like a college-aged drinking enthusiast hosing himself down with a can of Axe body spray before hitting the bars - has found what the Astronomy Picture of the Day blog calls "aurora unlike any other seen previously in our Solar System."
It's fascinating how in this image the aurora in question appears to form a dome over the already mysterious hexagonal cloud formation at Saturn's increasingly mysterious north pole. Insane speculation being par for the course in Ufology, I can't help but imagine all this hubub being caused by some powerful, alien technology beneath those clouds.
