Are We Alone - Skeptic Check: Doomsday at the Movies

ENCORE PRESENTATION: Hollywood has a few ideas of how the world will end: killer asteroids … lethal pandemics … deadly ice-ages. These themes have all played out on the big screen. But, hey, they’re only movies, right?

We’ll separate the science from the fiction in doomsday movies. From the 2012 prophesy of the Mayans … to colliding worlds … to abrupt climate change, find out which among this crowd of cinematic scares are for real, and which aren’t worth the price of popcorn.

A Tale of Planetary Woe

Source - NASA Science News for November 6, 2009

Long ago, something calamitous happened to Mars, transforming a warm and hospitable world into the frigid, seemingly lifeless desert we see today. Many scientists believe the Red Planet lost most of its atmosphere, but how? A new NASA mission named MAVEN is specifically designed to answer that question.

Are We Alone - Do Computers Byte?

The march of computer technology continues. But as silicon chips and search engines become faster and more productive – can the same be said for us?

The creator of Wolfram Alpha describes how his new “computational knowledge engine” is changing – and improving – how we process information. Meanwhile, suffering from data and distraction burnout? Find out what extremes some folks take to stop their search engines.

Also, the Singularity sensation of humans merging with machines… and, why for the ancient Greeks all of this is “been, there, done that.” A deep sea dive turns up a 2,000 year old computer!

Asteroid Explodes Over Indonesia

Source - Space Weather News for Oct. 28, 2009: http://spaceweather.com

INDONESIAN ASTEROID: Earlier this month, with no warning, a ~10-meter wide asteroid hit Earth's atmosphere above Indonesia and exploded. The break-up was so powerful, it triggered nuclear test ban sensors thousands of kilometers away. A just-released analysis of infrasound data shows that the asteroid detonated with an energy equivalent of about 50 kton of TNT, similar to a small atomic bomb. This significant impact has received relatively little attention in Western press. Details are available today on http://spaceweather.com.

SUNSPOT UPDATE: Since it emerged last weekend, new-cycle sunspot 1029 has become the biggest and most active sunspot of 2009. It is crackling with B- and C-class solar flares and putting on a good show for amateur astronomers. This one sunspot does not put an end to solar minimum, but it is a remarkable break from the calm.

The Sun's Sneaky Variability

Source - NASA Science News for October 27, 2009

It might not be obvious to the naked eye, but the sun is a variable star. A sensor slated for launch onboard NASA's Solar Dynamics Observatory will probe the sun's "sneaky variability" with better time and spectral resolution than ever before.

A Big Sunspot Emerges

Source - Space Weather News for Oct. 25, 2009: http://spaceweather.com

BIG SUNSPOT: The sun is showing signs of life. Sunspot 1029 emerged over the weekend, and it is crackling with B- and C-class solar flares. The active region's magnetic polarity identifies it as a member of new Solar Cycle 24. If its growth continues apace, sunspot 1029 could soon become the biggest sunspot of 2009. Check http://spaceweather.com for animations and updates.

MONDAY NIGHT SKY SHOW: When the sun sets on Monday, Oct. 26th, go outside and look south. Jupiter and the Moon are converging for a beautiful conjunction. The bright pair can been seen even through thinly-clouded skies and city lights. Don't miss it!

Are We Alone - Skeptic Check: Mind Your Body

Popping a pill may help when you’re sick… but maybe not for the reasons you think. Sugar pills – placebos – cure illness better than prescription pills in as many as half of all cases in clinical trials … and the placebo effect is getting stronger.

Plus, the safety – or otherwise – of electromagnetic waves, and the “electro-sensitive” refugees who have built a camp to protect themselves from waves they say are causing pain. Is it all in their minds?

And, New York Times reporter Dennis Overbye joins Phil Plait on the latest lapse in critically-thinking brains – a wild idea that may not be so loony: namely, could a cosmic censor from the future be thwarting efforts to find the Higgs boson?

It’s Skeptic Check … but don’t take our word for it! You can listen to this and other episodes at http://radio.seti.org/, and be sure to check out Are We A Blog?, the companion blog to the radio show.

Meteors from Halley's Comet

Source - Space Weather News for Oct. 20, 2009: http://spaceweather.com

METEORS FROM HALLEY'S COMET: Earth is entering a stream of dusty debris from Halley's Comet, and this is causing the annual Orionid meteor shower. If forecasters are correct, the shower will peak on Wednesday morning, Oct. 21st, with dozens of meteors per hour. The best time to look is during the dark hours before local dawn.

For the past three years, Orionid rates have been unusually high, with reports of 60 or more meteors per hour. Researchers believe this is a result of some very old and rich debris from Comet Halley drifting across Earth's orbit. Computer models of the debris suggest that it is still in the neighborhood, so the trend of "good Orionids" could continue in 2009. Visit http://spaceweather.com for photos and updates.

Are We Alone - Seth's Storage Locker

It’s always an adventure to go digging in Seth’s storage locker – who knows what we’ll find …

In this imposing pile of paraphernalia, tucked between boxes of socket wrenches and old 45s, we stumble upon the hunt for extrasolar planets, the evidence for water on moons of the solar system, theories of language, a controversial hypothesis for the peopling of the Americas, and a new dinosaur fossil.
