Geomagnetic Storm on May 31-June 1

Source - Space Weather News for May 31, 2013: http://spaceweather.com

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.

Big Picture Science for 05/27/13 - ZZZZZs Please

Big Picture Science - ZZZZZs Please

We’ve all hit the snooze button when the alarm goes off, but why do we crave sleep in the first place? We explore the evolutionary origins of sleep … the study of narcolepsy in dogs … and could novel drugs and technologies cut down on our need for those zzzzs.

Plus, ditch your dream journal: a brain scanner may let you record – and play back – your dreams.

And, branch out with the latest development in artificial light: bioluminescent trees. How gene tinkering may make your houseplants both grow and glow.

Guests:

• Emmanuel Mignot – Professor of psychiatry and behavioral sciences, and director of the Stanford Center for Sleep Sciences and Medicine, Stanford University
• Kyle Taylor – Molecular biologist at Glowing Plant
• Jerry Siegel – Neuroscientist and professor of psychiatry, the University of California, Los Angeles
• Jack Gallant – Professor of psychology and neuroscience, University of California, Berkeley

CME Strike on May 24th

Source - Space Weather News for May 24, 2013: http://spaceweather.com

CME STRIKE: As expected, a CME hit Earth's magnetic field on May 24th around 1800 UT. It was just a glancing blow. Nevertheless, the impact could spark polar geomagnetic storms in the hours ahead. High-latitude sky watchers should be alert for auroras shining through the bright moonlight on May 24-25.

CME and Solar Radiation Storm

Source - Space Weather News for May 22, 2013: http://spaceweather.com

SIGNIFICANT EXPLOSION: A solar radiation storm is in progress on May 22nd following an M5-class solar flare on the sun's western limb.  The explosion not only accelerated a hailstorm of protons toward our planet, but also produced a magnificent CME, which might deliver a glancing blow to Earth's magnetic field in the days ahead.

Big Picture Science for 05/20/13 - Skeptic Check: Hostile Climate

Big Picture Science - Skeptic Check: Hostile Climate

It’s a record we didn’t want to break. The carbon dioxide concentration in the atmosphere has hit the 400 parts-per-million mark, a level at which some scientists say is a point of no return for stopping climate change. A few days later, a leading newspaper prints an op-ed essay that claims CO₂ is getting a bad rap: it’s actually good for the planet. The more the better.

Skeptic Phil Plait rebuts the CO₂-is-awesome idea while a paleontologist paints a picture of what Earth was like when the notorious gas last ruled the planet. Note: humans weren’t around.

Plus, our skit says NO to O₂ … and a claim that climate change skeptics have borrowed from the Creationists’ playbook in challenging the teaching of established science in schools.

Guests:

• Phil Plait – Astronomer, Skeptic, and author of Slate Magazine’s blog Bad Astronomy
• Peter Ward – Paleontologist and biologist, Department of Earth and Space Sciences, University of Washington in Seattle
• Josh Rosenau – Programs and Policy Director at the National Center for Science Education

Strong Solar Activity Continues

Source - Space Weather News for May 14, 2013: http://spaceweather.com

Solar activity is high.  During a 24 hour period straddling May 13th and 14th, the sun unleashed three X-class solar flares.  These are the strongest flares of the year so far, and they signal a significant increase in solar activity.  The source of the flares, a large sunspot on the sun's eastern limb, appears poised to erupt again as it turns toward Earth.

Check http://spaceweather.com for updates and more information.

X-Flare on May 13th

Source - Space Weather News for May 13, 2013: http://spaceweather.com

X-FLARE: A sunspot hiding behind the sun's eastern limb erupted on May 13th at 02:17 UT, producing the strongest solar flare of the year so far (X1.7).  The blast site  will turn toward Earth in a few days. This will give forecasters a better view of the active region and allow them to gauge its potential for more explosions. Visit http://spaceweather.com for updates and images of today's X-flare.

You’ll hear how Stephen King thinks that humankind is metaphorically living under a big dome, and what reasons Neil Tyson gives for why we really want to go into space.

And … skeptical takes on faces in cheese sandwiches and the supposedly special powers of psychics.

ANNULAR ECLIPSE: On May 10th, the South Pacific sun will turn into a ring of fire as the Moon passes directly in front of the solar disk, producing an annular solar eclipse. At maximum, more than 95% of the sun's diameter will be covered over parts of Australia, eastern Papua New Guinea and the Solomon Islands. Please check http://spaceweather.com for more information, including a live webcast from Cape York, Australia, which begins on May 9th at approximately 5 PM EDT.
