Satellites See Unprecedented Greenland Ice Sheet Surface Melt

Source - NASA Science News for July 24, 2012

For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland experienced some degree of melting, according to measurements from three independent satellites.

CME Impact on Oct. 24

Source - Space Weather News for Oct. 24, 2011: http://spaceweather.com

CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field on Oct. 24th around 1800 UT (2 pm EDT). The impact strongly compressed our planet's magnetosphere and may have exposed geosynchronous satellites to solar wind plasma. Mild to moderate geomagnetic storms are possible in the hours ahead as Earth's magnetic field continues to reverberate from the hit. Sky watchers in Scandinavia, Canada, and northern-tier US States should be alert for auroras, especially during the hours around local midnight. Check http://spaceweather.com for updates.

Are We Alone for 06/28/10 - Home Brew Science

Are We Alone - Home Brew Science

The recipe for being a scientist was easy in the old days… just be born into a rich family, have an interest in nature and plenty of time to indulge yourself. But are the days of gentlemen scientists over? Maybe not.

We go to the Maker Faire and check out how small-scale projects have big-scale ambitions.

Also, how everyday experience often tells us something profound about the universe.

Guests:

• Spencer Weart - Former director of the Center for the History of Physics, at the American Institute of Physics
• Tim Russ - Actor, and the character Tuvok on Star Trek Voyager
• Marcus Chown - Science writer and author of The Matchbox That Ate a Forty-Ton Truck: What Everyday Things Tell Us About the Universe
