Big Picture Science for July 17, 2017 - Eclipsing All Other Shows












Big Picture Science - Eclipsing All Other Shows

They say that the experience of watching a total eclipse is so profound, you’re not the same afterward.  If life-changing events are your thing and you’re in the lower 48 states on August 21st, let us help you make the most of viewing the Great American Solar Eclipse.

Learn the basics of where to be and what to bring, even on short notice. No eclipse glasses?  Find out why a kitchen colander is an excellent Plan B.

Also, the strange behavior of animals and private jet pilots during an eclipse.  The latter is making the FAA sweat.

Plus, how 1878 eclipse fever inspired Thomas Edison and astronomer Maria Mitchell, and what was at stake for them scientifically.  And today, with astronauts able to view the Sun from space, what new science can we still learn by eclipse expeditions on Earth?

And, NASA turns up the heat on solar studies with a probe to within a hair’s breadth of the Sun.

CME Strike Sparks Geomagnetic Storms

CME STRIKE SPARKS GEOMAGNETIC STORMS: Geomagnetic storms are underway on July 16th following a CME strike at 0545 UT. Auroras have been sighted in New Zealand as well as US states such as Washington and Wyoming. G1-class storms happening now could intensity to G2-class in the hours ahead as Earth moves into the CME's magnetized wake.

Solar Activity Intensifies as Huge Sunspot Grows


Source - Space Weather News for July 9, 2017: http://spaceweather.com

SOLAR ACTIVITY INTENSIFIES: Sunspot AR2665, which emerged just as few days ago, has mushroomed into a behemoth nearly as wide as the planet Jupiter. On July 9th the fast-growing sunspot produced an M-class solar flare and a short-lived shortwave radio blackout over east Asia and Australia. Stronger flares and Earth-directed CMEs may be in the offing as AR2665 turns toward our planet in the days ahead.

Big Picture Science for July 10, 2017 - Frogs' Pants












Big Picture Science - Frogs' Pants

It’s one of the most bizarre biological experiments ever. In the 18th century, a scientist fitted a pair of tailor-made briefs on a male frog to determine the animal’s contribution to reproduction.  The process of gestation was a mystery and scientists had some odd-ball theories.

Today, a 5th grader can tell you how babies are made, but we still don’t know exactly what life is.  In our quest to understand, we’re still at the frogs’ pants stage.

Find out why conception took centuries to figure out.  Also, why the 1970s Viking experiments, specifically designed to detect life on Mars, couldn’t give us a definitive answer.  Plus, can knowing where life isn’t help define what it is?  Take a tour of the world’s barren places.

A Big Sunspot is Turning Toward Earth


Source - Space Weather News for July 7, 2017: http://spaceweather.com

BIG SUNSPOT TURNS TOWARD EARTH: A new and large sunspot is rapidly growing on the solar disk, temporarily arresting the sun's plunge into Solar Minimum. Stretching more than 70,000 km from end to end, the active region numbered AR2665 has more than doubled in size in 24 hours. This makes it an easy target for backyard solar telescopes. So far the growing sunspot has not produced any strong flares, but this could change if its rapid growth continues apace and destabilizes the sunspot's magnetic field.

Big Picture Science for July 03, 2017 - Skeptic Check: Rational Lampoon












Big Picture Science - Skeptic Check: Rational Lampoon

Two heads may be better than one.  But what about three or more?  A new study shows that chimpanzees excel at complex tasks when they work in groups, and their accumulated knowledge can even be passed from one generation to the next.

But group-think also can be maladaptive.  When humans rely on knowledge that they assume other people possess, they can become less than rational.

Find out why one cognitive scientist says that individual thinking is a myth.  Most of your decisions are made in groups, and most derive from emotion, not rationality.

Also, why we know far less than we think we do.  For example, most people will say they understand how an everyday object like a zipper works, but draw a blank when asked to explain it.

Plus, why we have a biological drive to categorize people as “us” or “them,” and how we can override it.
