Big Picture Science for 06/17/13 - Exoplanets

Image for Big Picture Science weekly radio show
Big Picture Science - Exoplanets

You may be unique, but is your home planet? NASA’s Kepler spacecraft has uncovered thousands of planetary candidates, far far beyond our solar system. Some may be habitable and possibly even Earth-like. But now a failure in its steering apparatus may bring an abrupt end to this pioneering telescope’s search for new worlds.

But Kepler has a massive legacy of data still to be studied. Many new worlds will undoubtedly be found in these data. Hear why the astronomer who has discovered the greatest number of exoplanets is hopeful about the hunt for alien life, and meet the next generation of planet-hunting instruments.

Also, “Weird worlds? That was our idea!” Sci-fi writers lay claim to the first musings on exotic planetary locales. And a biographer of Magellan and Columbus describes the dangerous hunt for new worlds five centuries ago.

Dry Ice "Snowboards" on Mars


Source - NASA Science News for June 11, 2013

New research suggests that some of the famous gullies on Mars are caused by slabs of dry ice gliding down sand dunes on cushions of gas similar to miniature hovercraft.

Possible Meteor Shower on June 11


Source - Space Weather News for June 10, 2013: http://spaceweather.com

METEOR SHOWER: Sky watchers in North America might see an outburst of meteors during the early hours of June 11th when Earth passes through a stream of cometary debris last seen in 1930. Forecasters predict the return of the gamma Delphinid meteor shower this Tuesday morning around 08:30 UT (04:30 am EDT). The shower is expected to last about 30 minutes with an unknown number of bright, fast meteors.

Big Picture Science for 06/10/13 - This Land Is Island

Big Picture Science - This Land Is Island

There are many kinds of islands. There’s your iconic sandy speck of land topped with a palm tree, but there’s also our home planet – an island in the vast seas of space. You might think of yourself as a biological island … until you tally the number of microbes living outside – and inside – your body.

We go island hopping, and consider the Scottish definition of an island – one man, one sheep – as well as the swelling threat of high water to island nations. Also, how species populate islands … and tricks for communicating with extraterrestrial islanders hanging out elsewhere in the cosmos.

Northern Lights in the USA


Source - Space Weather News for June 7, 2013: http://spaceweather.com

GEOMAGNETIC STORMS: Last night, Earth passed through a region of south-pointing magnetism in the solar wind. This triggered a G2-class (Kp=6) geomagnetic storm. At its peak, the storm spawned Northern Lights in the USA as far south as Kansas. More auroras are in the offing as a CME is set to deliver a glancing blow to Earth's magnetic field on June 8-9.  Check http://spaceweather.com for photos and updates.

Big Picture Science for 06/03/13 - Cosmos: It's Big, It's Weird

Big Picture Science - Cosmos: It's Big, It's Weird

ENCORE: It’s all about you. And you, and you, and you and you… that is, if we live in parallel universes. Imagine you doing exactly what you’re doing now, but in an infinite number of universes.

Discover the multiverse theory and why repeats aren’t limited to summer television.

Plus, the physics of riding on a light beam, and the creative analogies a New York Times science writer uses to avoid using the word “weird” to describe dark energy and other weird physics.

Also, people who concoct their own theories (some would say fringe) of the universe: is all matter made up of tiny coiled springs?

Aurora Surprise: Northern Lights in the USA


Source - Space Weather News for June 1, 2013: http://spaceweather.com

AURORA SURPRISE:  Last night, Northern Lights spilled across the Canadian border and descended into the contiguous United States as far south as Colorado and Nebraska.  The display was caused by the unexpected arrival of an interplanetary shock wave on May 31st.  Check http://spaceweather.com for pictures of the display and the odds of a repeat performance tonight.

DID YOU MISS THE STORM?  Next time get a wake-up call.  Aurora and solar flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

GEOMAGNETIC STORM: An interplanetary shock wave (possibly a CME) hit Earth's magnetic field during the late hours of May 31st, sparking a polar geomagnetic storm. At the time of this alert, a G1-class storm is underway and solar wind conditions favor high-latitude auroras.
