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 - Animal Instinct

ENCORE: Mooooove over, make way for the cows, the chickens … and other animals! Humans can learn a lot from our hairy, feathered, four-legged friends. We may wear suits and play Sudoku, but Homo sapiens are primates just the same. We’ve met the animal, and it is us.

Discover the surprising similarity between our diseases and those that afflict other animals, including pigs that develop eating disorders. Plus, what the octopus can teach us about national security … how monkeying around evolved into human speech … and the origins of moral behavior in humans.

Electric Blue Clouds Appear Over Antarctica


NASA Science News for Dec. 23, 2013

A vast bank of electric-blue clouds has appeared over Antarctica, signaling the start of the season for southern hemisphere noctilucent clouds.

Big Picture Science for 12/23/13 - Group Think

Image for Big Picture Science weekly radio show
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.

Big Picture Science for 12/16/13 - Some Like It Cold

Image for Big Picture Science weekly radio show
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 "Magic Hour" for Geminid Meteors


Source - NASA Science News for Dec. 13, 2013

The Geminid meteor shower is underway. Forecasters say the best time to look is during the dark hours before sunrise on Saturday morning, Dec. 14th. Dark-sky observers could see dozens of bright shooting stars.

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?

The Coldest Place on Earth


Source - NASA Science News for Dec. 10, 2013

Earth-orbiting satellites have found the coldest place on Earth. It's a group of hollows in Antarctica where temperatures can dip below minus 133.6 degrees Fahrenheit (minus 92 degrees Celsius) on a clear winter night.

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.

What Happened to Comet ISON?


Source - NASA Science News for Dec. 04, 2013

In full view of the NASA-ESA solar physics fleet, Comet ISON disintegrated when it flew through the sun's atmosphere on Thanksgiving Day. Researchers are still marveling at the images and the scientific data they contain.

Big Picture Science for 12/02/13 - Math's Days Are Numbered

Image for Big Picture Science weekly radio show
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.
