GEMINID METEOR SHOWER: This weekend, Earth will pass through a stream of debris from extinct comet 3200 Phaethon, source of the annual Geminid meteor shower. Forecasters expect more than 100 meteors per hour to fly out of the constellation Gemini when the shower peaks on Dec. 13th and 14th. For most observers, the best time to look will be from 10 pm local time on Sunday night to dawn on Monday morning.

Stunning Spiral Light Show over Norway

Source - Space Weather News for Dec. 9, 2009: http://spaceweather.com

This morning in arctic Norway, onlookers were stunned when a gigantic luminous spiral formed in the northern sky. Veteran observers accustomed to the appearance of Northern Lights say they have never seen anything like it. It was neither a meteor nor any known form of atmospheric optics. Rumors that the spiral was caused by the botched launch of a Russian rocket have not yet been confirmed.

Are We Alone - Carbon Your Enthusiasm

Bond it to oxygen and it’s the scourge of climate change. But earthly life wouldn’t be possible without carbon, and maybe that’s true for alien life, too.

And carbon has other exciting forms: tiny diamonds may be evidence of a catastrophic comet impact 13,000 years ago. And, chalky carbonates may point to a once-habitable Mars.

So get cozy with carbon. Find out if you could swap it for silicon in DNA. Plus, the conundrum of calculating a carbon footprint.

Great Fireball over the Western USA

Source - Space Weather News for Nov. 18, 2009: http://spaceweather.com

FIREBALLS AND METEORS: As forecasters predicted, the Leonid meteor shower peaked during the late hours of Nov. 17th, favoring sky watchers in Asia with an outburst of 100+ meteors per hour. Just as the outburst was dying down, an even bigger event took place over the western USA. Something hit Earth's atmosphere and exploded with an energy equivalent of 0.5 to 1 kiloton of TNT. Witnesses in Colorado, Utah, Idaho and elsewhere say the fireball "turned night into day" and "shook the ground" when it exploded just after midnight Mountain Standard Time. Researchers who are analyzing infrasound recordings of the blast say the fireball was not a Leonid. It was probably a small asteroid, now scattered in fragments across the countryside. Efforts are underway to measure the trajectory of the asteroid and guide meteorite recovery efforts.

Are We Alone - SETI: Now What?

Hello! Is anyone out there? As the scientific search for extraterrestrial intelligence marks its 50th anniversary, there’s been no contact as yet with alien beings. But SETI researchers maintain that we are not alone. Find out why in a SETI retrospective that looks at the past and future of the search.

We remember the first scientific SETI search… Carl Sagan… how the SETI Institute began… the WOW signal…and the 1993 NASA budget cuts.

We’ll also hear from critics of the search… scientists involved in optical SETI and SETI@home. Plus, international collaborations… and where the search is headed.
