Must-See Sunset Phenomenon
Source - Space Weather News for Dec. 30, 2013: http://spaceweather.com
MUST-SEE SUNSET PHENOMENON: Like the Moon, Venus has phases, and this week the second planet from the sun is a whisper-thin crescent. The phenomenon is easy to observe. Venus is so bright, you can see it at sunset even before the sky fades to black (hint: face southwest). A pair of binoculars or a small telescope reveals Venus's crescent shape.
Check http://spaceweather.com for photos and more information.
AURORA WATCH: A solar wind stream is approaching Earth and could spark the first auroras of 2014 when it arrives on Jan. 2-4. Would you like a call when the sky lights up? Geomagnetic storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Big Picture Science for 12/23/13 - Group Think
Big Picture Science - Group Think
ENCORE: If two is company and three a crowd, what’s the ideal number to write a play or invent a new operating system? Some say you need groups to be creative. Others disagree: breakthroughs come only in solitude.
Hear both sides, and find out why you always have company even when alone: meet the “parliament of selves” that drive your brain’s decision-making.
Plus, how ideas of societies lead them to thrive or fall, and why educated conservatives have lost trust in science.
Guests:
- Susan Cain – Author of Quiet: The Power of Introverts in a World That Can’t Stop Talking
- Keith Sawyer – Psychologist at Washington University in St. Louis and author of Group Genius: The Creative Power of Collaboration

Big Picture Science for 12/16/13 - Some Like It Cold
Big Picture Science - Some Like It Cold
We all may prefer the goldilocks zone – not too hot, not too cold. But most of the universe is bitterly cold. We can learn a lot about it if we’re willing to brave a temperature drop.
A chilly Arctic island is the closest thing to Mars-on-Earth for scientists who want to go to the Red Planet. Meanwhile, the ice sheet at the South Pole is ideal for catching neutrinos – ghostly particles that may reveal secrets about the nature of the universe.
Comet ISON is comet ice-off after its passage close to the Sun, but it’s still giving us the word on solar system’s earliest years.
Also, scientists discover the coldest spot on Earth. A champion chill, but positively balmy compared to absolute zero. Why reaching a temperature of absolute zero is impossible, although we’ve gotten very, very close.
Guests:
- Francis Halzen – Physicist, University of Wisconsin-Madison, principal investigator of The IceCube Neutrino Observatory
- Ted Scambos – Glaciologist, lead scientist, National Snow and Ice Data Center, University of Colorado
- Pascal Lee – Planetary scientist, SETI Institute, director, NASA Haughton-Mars Project, and co-founder of the Mars Society. His new book is Mission: Mars
- Andrew Fraknoi – Chair, astronomy department, Foothill College
- Vladan Vuletić – Physicist, Massachusetts Institute of Technology

The Geminid Meteor Shower is Underway
Source - Space Weather News for Dec. 12, 2013: http://spaceweather.com
GEMINID METEOR SHOWER: Earth is entering a stream of debris from "rock comet" 3200 Phaethon, source of the annual Geminid meteor shower. Last night, NASA cameras recorded more than a dozen fireballs over the USA. Geminid activity should remain relatively high for the next three or four nights, with a peak expected on Dec. 13-14. Check http://spaceweather.com for more information and observing tips.
GEOMAGNETIC STORM: On Dec. 7th, a solar wind stream hit Earth's magnetic field, sparking an unexpected geomagnetic storm and Northern Lights over several US states. Did you miss it?

Andromedid Meteor Outburst
Source - Space Weather News for Dec. 8, 2013: http://spaceweather.com
METEOR OUTBURST: The Canadian Meteor Orbit Radar is detecting echoes from a meteor outburst in the constellation Andromeda, in progress on Dec. 8th. It appears to be debris from old Comet Biela, which broke apart in the 19th century. Observers in the northern hemisphere, especially Europeans, should be alert for Andromedid meteors on the night of Dec. 8-9. More information may be found at http://spaceweather.com.
GEOMAGNETIC STORM: A solar wind stream hit Earth's magnetic field on Dec. 7th, sparking an unexpected geomagnetic storm and Northern Lights over numerous US states. NOAA forecasters estimate a 35% chance of additional storms on Dec. 8th and 9th.

Big Picture Science for 12/09/13 - Monster Mashup
Big Picture Science - Monster Mashup
Monsters don’t exist. Except when they do. And extinction is forever, except when it isn’t. So, which animals are mythical and which are in hiding?
Bigfoot sightings are plentiful, but real evidence for the hirsute creature is a big zilch. Yet, the coelacanth, a predatory fish thought extinct, actually lives. Today, its genome is offering clues as to how and when our fishy ancestors first flopped onto land.
Meanwhile, the ivory-billed woodpecker assumes mythic status as it flutters between existence and extinction. And, from passenger pigeons to the wooly mammoth, hi-tech genetics may imitate Jurassic Park, and bring back vanished animals.
Guests:
- Donald Prothero – Paleontologist, geologist, former professor at Occidental College, co-author of Abominable Science!: Origins of the Yeti, Nessie, and Other Famous Cryptids
- Chris Amemiya – Biologist and geneticist at the University of Washington and the Benaroya Research Institute, Seattle
- John Fitzgerald – Ornithologist and director, Cornell Lab of Ornithology, Cornell University

Big Picture Science for 12/02/13 - Math's Days Are Numbered
Big Picture Science - Math's Days Are Numbered
Imagine a world without algebra. We can hear the sound of school children applauding. What practical use are parametric equations and polynomials, anyway? Even some scholars argue that algebra is the Latin of today, and should be dropped from the mandatory curriculum.
But why stop there? Maybe we should do away with math classes altogether.
An astronomer says he’d be out of work: we can all forget about understanding the origins of the universe, the cycles of the moon and how to communicate with alien life. Also, no math = no cybersecurity + hackers (who have taken math) will have the upper hand.
Also, without mathematics, you’ll laugh < you do now. The Simpsons creator Matt Groening has peppered his animated show with hidden math jokes.
And why mathematics = love.
Guests:
- Andrew Hacker – Professor of political science and mathematics at Queens College, City University of New York. His article, “Is Algebra Necessary?”, appeared in The New York Times in 2012.
- Bob Berman – Astronomy editor of The Old Farmer’s Almanac, the author of The Sun’s Heartbeat: And Other Stories from the Life of the Star That Powers Our Planet, and columnist for Astronomy Magazine. His article, “How Math Drives the Universe” is the cover story in the December 2013 issue.
- Simon Singh – Science writer, author of The Simpsons and Their Mathematical Secrets
- Rob Manning – Flight system chief engineer at the Jet Propulsion Lab, responsible for NASA’s Curiosity rover
- Edward Frenkel – Professor of mathematics at the University of California, Berkeley, author of Love and Math: The Heart of Hidden Reality. His article, “The Perils of Hacking Math,” is found on the online magazine, Slate.
