    See a meteor shower in a minute

    Meteor showers are marvelous sights, as myriads of stargazers found out a week ago. But seeing them can sometimes be inconvenient. To get the best view, you have to go far from city lights and stay up until the wee hours of the morning. The ideal situation would be to camp out in a beautiful location like California's Joshua Tree National Park and keep your eyes open all night.

    That's exactly what photographer Henry Jun Wah Lee did last week. He set up his camera in the park for two nights around the peak of the Perseid meteor shower (Aug. 12 and 15), took a series of exposures, and spliced them together artfully into a multi-day time-lapse sequence.


    The result makes it seem as if the meteors are popping like fireworks amid the multitudes of stars in the Milky Way ... two nights' worth in just a little more than minute. But not all of the flashes you see are shooting stars.

    "I did catch some airplanes," Lee told me today. The streaks that appear to move across the sky are more likely nighttime airplane transits rather than meteors. But there's a killer meteor flash that pops up around the 30-second mark, leaving a little wisp of vapor in its wake.

    "When that happened, it lit up the whole sky like a flash of lightning," Lee said.

    For still more August awesomeness, check out the Perseid meteor gallery at SpaceWeather.com.

    The Perseid show is pretty much over, as this activity graph from the International Meteor Organization illustrates. But there's more to come: The highlights ahead include the Leonids of Nov. 17 and the Geminids of Dec. 13-14. That timetable should give you enough advance warning to scope out a picturesque viewpoint ... at Joshua Tree or closer to home.

    SpaceX's Falcon 9 launch sparks UFO reports in Australia

    Bad Astronomy's Phil Plait explains why all those UFO reports about "sky spirals" seen over Australia were caused by the rocket exhaust from the Falcon 9's second stage. It's a rerun of last December's Norwegian sky-spiral sighting. Similar swirls have been seen in the wake of Chinese missile tests as well, by the way. The truth is out there ... on the Web!

    Betelgeuse sparks doomsday debate

    L. Calcada / ESO

    Betelgeuse has a vast plume of gas almost as large as our solar system and a gigantic bubble boiling on its surface, as shown in this artist's impression.

    Is the constellation Orion's famous red supergiant due to go supernova sometime in the next few months? Mmmm, not likely, says Phil Plait, the scientist and skeptic who runs the Bad Astronomy website. And even if Betelgeuse does blow up, it won't pose a threat to Earth, he says.

    Plait should know. He's the author of "Death From the Skies," a book that goes into supernovae and other bad things that the cosmos can dish out. The buzz started with a posting on the Life After the Oil Crash Forum, claiming that Betelgeuse's blast might "burn the crops" and "freak everybody out." Plait weighed in with the reasons why that won't be the case.

    It is true that Betelgeuse appears to be shedding mass and looks as if it might explode sometime in the next 10,000 years or so. But it's hard to pinpoint exactly when the end will come - and at a distance of 600 light-years, the blast won't have a big effect on Earth, Plait says.

    The doomsday talk is reminiscent of earlier scares over the Large Hadron Collider and 2012's approach. And the bottom line is the same: DON'T PANIC!
