Big Picture Science for September 11, 2017 - Plan of a Hack

Big Picture Science - Plan of a Hack

Long before cyber criminals were stealing ATM passwords, phone phreaks were tapping into the telephone system. Their motivation was not monetary, but the thrill of defeating a complex, invisible network. Today “hacking” can apply to cyberwarfare, biological tinkering, or even geoengineering.  Often it has negative connotations, but the original definition of “hacking” was something else.

In this first of two episodes on hacking, we look at the original practitioners – the teenagers and mavericks who hacked Ma Bell for thrills - and the difference between hacking for fun and for profit. 

Guests:

• Phil Lapsley - Author of “Exploding the Phone: The Untold Story of the Teenagers and Outlaws Who Hacked Ma Bell”

Geomagnetic Storm Warning

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

GEOMAGNETIC STORM WARNING: A CME has just hit Earth's magnetic field (Sept. 7th at ~2300 UT). This is the debris from Wednesday's decade-class X9 solar flare. It arrived earlier than expected, confirming that the solar storm cloud is both fast and potent. The CME appears to contain strong south-pointing magnetic fields that typically do a good job of igniting geomagnetic storms. High-latitude sky watchers should be alert for auroras in bright moonlight.

SUNSPOT GENESIS: Two big sunspot groups are now facing Earth. Behemoth AR2674 has been growing for days, while newcomer AR2673 has suddenly quadrupled in size, with multiple dark cores breaching the surface of the sun in just the past 24 hours. The rapid development of these regions could herald Earth-directed flares in the days ahead.

Big Picture Science for September 04, 2017 - Born Legacy

Big Picture Science - Born Legacy

ENCORE:  We know how the stars shine, but how do you make a star?  We take an all-night ride on a high-flying jet – an airborne observatory called SOFIA – to watch astronomers investigate how a star is born.

As for how the universe was born, we know about the Big Bang but modern physics suggests that similar cosmic explosions may be happening all the time, and even hint that we could – in principle – create a new universe in a laboratory.  What does this mean, and how could we do it?

From stars to universes, how it all came to be.

Guests:

• Zeeya Merali – Journalist and editor for the Foundational Questions Institute, author of A Big Bang in a Little Room: The Quest to Create New Universes
• Nick Veronico – Manager of SOFIA Communications for NASA Ames Research Center and Universities Space Research Association

A New Kind of Upper Atmospheric Lightning?

Source - Space Weather News for August 31, 2017: http://spaceweather.com

A NEW KIND OF UPPER ATMOSPHERIC LIGHTNING? In recent years, photographers have catalogued a growing number of luminous forms apparently leaping up from the tops of thunderstorms. These so-called sprites, elves, gnomes, and trolls inhabit the upper atmosphere, reaching their weird-looking tendrils up toward space. On Aug. 14th, an amateur astronomer in New Mexico photographed a rare curving form of upper atmospheric lightning that has baffled experts in the field. Shaped like a funnel or a tornado, it might represent a new addition to the menagerie of sprites.

GEOMAGNETIC STORM IN THE OFFING: A canyon-shaped hole has opened in the sun's atmosphere, and it is spewing a stream of high-speed solar wind toward Earth. NOAA forecasters say there is a 30% chance of polar geomagnetic storms (G1-class) when the gaseous material reaches our planet on August 31st. High-latitude sky watchers should be alert for auroras this Thursday and Friday.

Visit Spaceweather.com for photos and updates

Image Information: This canyon-shaped "coronal hole" is a region in the sun's atmosphere where the sun's magnetic field has opened up, allowing solar wind to escape.

Big Picture Science for August 28, 2017 - Elements Never Forget

Big Picture Science - Elements Never Forget

ENCORE: It’s elementary, Watson.  Things are in flux – from the elements in the air you breathe to party balloons.   We investigate the massive, historic loss of nitrogen from the atmosphere and meet the culprits behind a modern-day helium shortage.

But it’s not all a disappearing act: be thankful that oxygen showed up in our atmosphere a few billion years ago.  Meanwhile, atom smashers have recently produced some new elements.  Their appearance was brief, but long enough to fill out the periodic table.

And perhaps the tastiest use of an element – one that gives Seth a chilly reception.

Guests:

• Inna Vishik – Postdoctoral fellow in physics at MIT
• Roland Pease – Science reporter in the U.K.
• Mark Stoyer – Nuclear chemist, Lawrence Livermore National Laboratory

Big Picture Science for August 21, 2017 - Musical Universe

Big Picture Science - Musical Universe

ENCORE: In space, no one can hear you scream, but, using the right instruments, scientists can pick up all types of cosmic vibrations – the sort we can turn into sound.  After a decade of listening, LIGO, a billion-dollar physics experiment, has detected gravitational waves caused by the collision of massive black holes, a brief shaking of spacetime that can be translated into a short squeal.

We listen to the chirp of black holes crashing into each other and wonder: could the universe contain more than individual sounds, but have actual musical structure?

A theoretical physicist and jazz saxophonist updates the ancient philosophical concept of the Music of the Spheres to probe the most vexing questions confronting modern cosmology.  Find out how the evolution of the universe resembles an improvisational jazz piece, and the musical inspiration John Coltrane drew from Albert Einstein.

Guests:

• Janna Levin – Physicist, astronomer, Barnard College at Columbia University, author of “Black Hole Blues and Other Songs from Outer Space”
• Stephon Alexander - Professor of physics, Brown University, author of “The Jazz of Physics: The Secret Link Between Music and the Structure of the Universe”

New Predictions for the Solar Eclipse

Source - Space Weather News for August 16, 2017: http://spaceweather.com

NEW PREDICTIONS FOR THE SOLAR ECLIPSE: Next Monday, Aug. 21st, the Moon will pass directly in front of the sun producing an historic solar eclipse over the USA.  Millions of people inside the path of totality will catch a glimpse of the sun's gossamer outer atmosphere, the corona. In centuries past, the appearance of the corona was unpredictable from one eclipse to the next. But now researchers have developed supercomputer codes to forecast its shape.

New predictions for the "Great American Solar Eclipse" are highlighted on today's edition of Spaceweather.com

Big Picture Science - On Thin Ice

Water is essential for life – that we know.  But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life.

Ice is more than a repository for water that would otherwise raise sea levels.  It’s part of Earth’s cooling system, a barrier preventing decaying organic matter from releasing methane gas, and a vault entombing ancient bacteria and other microbes.

From the Arctic to the Antarctic, global ice is disappearing.  Find out what’s at stake as atmospheric CO2 threatens frozen H2O.

Guests:

• Peter Wadhams - Emeritus Professor of Ocean Physics at Cambridge University in the U.K. and the author of A Farewell to Ice: A Report from the Arctic
• Eric Rignot - Earth systems scientist, University of California, Irving, senior research scientist, NASA Jet Propulsion Laboratory

Watch Out for Perseid Fireballs this Weekend

Source - Space Weather News for August 11, 2017: http://spaceweather.com

PERSEID FIREBALLS: The Perseid meteor shower, which peaks this weekend (Aug. 12-13), produces more fireballs than any other known annual meteor shower. (Fireballs are meteors brighter than Jupiter or Venus.) This characteristic of the Perseids is important because in 2017 the shower peaks under the light of a bright gibbous Moon. Perseid fireballs should be visible in spite of lunar interference, producing a pleasing display for anyone outdoors before sunrise on Saturday and Sunday.

Visit Spaceweather.com for observing tips.
