Oh, yon flaming orb. Every day, Helios’s chariot carries you across the sky.
Well, perhaps not: but the 27 million degree star that rules our every waking hour actually has a beating heart. Well, a pulse.
Anyway, it also generates a kajillion fascinating facts — did you know you get more Vitamin D from ten minutes in the sun than 200 glasses of milk?
We explore stories of the star, its eclipses, storms, shelf-life and why somewhere over the rainbow, it’s way up high.
From Science Hack Day: the Best Science Hack winners and their robots.
Guests: Ariel Waldman founder of Spacehack.org, Christie Dudley of Team FREDnet, Geoffrey Chu and Matt Everingham of NASA Ames Research Center, David Burchanowski of awesomenessinabox.com and Jade Wang, neuroscientist at NASA
Humans have not gone unnoticed on this planet. We’ve left our mark with technology, agriculture, architecture, and a growing carbon footprint. But where is this trajectory headed?
In the second of a two-part series: what we’ll lose and what will last in 1000 years or more.
Discover what the planet might look like to geologists of the far-off-future… the stubborn longevity of plastic and radioactive waste… human civilization in space… and postcards from the galactic edge; crafting interstellar messages to E.T.
Guests:
Charles Moore – Sea Captain and founder of Algalita Marine Research Foundation Jan Zalasiewicz – Geologist, University of Leicester and author of The Earth After Us: What Legacy Will Humans Leave in the Rocks? Matthew Wald – Reporter for the New York Times and author of the article “Is There a Place for Nuclear Waste?” in the August 2009 issue of Scientific American Doug Vakoch – Director of Interstellar Message Composition at the SETI Institute David Korsmeyer – Chief of the Intelligent Systems Division at NASA Ames Research Center
NASA astronaut Don Pettit spent nearly six months aboard the International Space Station and elected to spend his off-duty time performing science experiments of his own design. Pettit talks about life in space and some of the gadgets he invented while he lived there.

Dr. Robot, I presume? Your appendix may be removed by motor-driven, scalpel-wielding mechanical hands one day. Robots are debuting in the medical field… as well as on battlefields. And they’re increasingly making important decisions – on their own. But can we teach robots right from wrong? Find out why the onslaught of silicon intelligence has prompted a new field of robo-ethics.
Plus, robo-geologists: NASA’s vision for autonomous robots in space.
Guests:
Dr. Brendan Quine discusses his design for a novel kind of space elevator.
