Minor Geomagnetic Storms Likely Dec. 7-10


Source - Space Weather News for Dec. 7, 2016: http://spaceweather.com

GEOMAGNETIC STORM WATCH: Minor G1-class geomagnetic storms are likely for the next three to four days as Earth passes through a stream of high-speed solar wind. A type of shock wave at the leading edge of the stream called a "co-rotating interaction region" (CIR) could spark a display of bright Arctic auroras as early as Dec. 7-8.

Visit Spaceweather.com for updates about the coming storms.

Big Picture Science for Monday December 5, 2016 - Brain Dust












Big Picture Science - Brain Dust

Know your brain?  Think again.  Driven by a hidden agenda, powered by an indecipherable web of neurons, and influenced by other brains, your grey matter is a black box.

To "know thyself" may be a challenge, and free will nonexistent, but maybe more technology can shed light on the goings on in your noggin, and the rest of your body.

Find out how tiny implanted sensors called “brain dust” may reveal what really going on.

Plus, the day when your brain is uploaded into a computer as ones and zeros.  Will you still be you?

What is the "Da Vinci Glow"? You can see it this weekend...


Source - Space Weather News for Dec. 3, 2016: http://spaceweather.com

WHAT IS THE DA VINCI GLOW?  Five hundred years ago, Leonardo da Vinci proposed an outlandish theory explaining why the Moon's surface glows during the lunar night. Turns out, his idea was correct. This weekend is a great time to see the "Da Vinci Glow" for yourself. Observing tips and the full story of da Vinci's imaginative leap are highlighted on today's edition of Spaceweather.com.

LARGE CORONAL HOLE TURNING TOWARD EARTH:  A large hole in the sun's atmosphere has formed and it is turning toward Earth.  Solar wind emerging from the opening could reach Earth as early as Dec. 6-7 and influence the space environment of our planet for several days.

Weird Upper-Atmospheric Wave Ripples across China


Source - Space Weather News for Nov. 30, 2016: http://spaceweather.com

WEIRD ATMOSPHERIC WAVE RIPPLES OVER CHINA: On Nov. 24th, a deep-rippling wave at the edge of space crossed the night sky above China. Eye-witnesses saw the airglow layer split in two, and at least one photographer captured beautiful images of the event.  It might be a type of exotic wave called a "mesospheric bore."

Visit Spaceweather.com to see the photos and learn more.

UNEXPECTED SOLAR FLARES: Catching forecasters off guard, a new sunspot (AR2615) has emerged and it is crackling with M-class solar flares. Minor radio blackouts are underway on Nov. 29-30 as pulses of UV and X-radiation ionize the top of Earth's atmosphere.  This is *not* a major space weather event, but it is a break from the sun's recent deepening quiet.

Electric-blue Clouds Appear over Antarctica

NOCTILUCENT CLOUDS OVER ANTARCTICA: This just in from NASA's AIM spacecraft: The sky above Antarctica is glowing electric blue. A ring of bright noctilucent clouds has formed around the South Pole. The annual apparition of these clouds is one of the earliest on record, and may hint at the workings of climate change.

Big Picture Science for Monday November 28, 2016 - What Lies Beneath












Big Picture Science - What Lies Beneath

ENCORE: What you can’t see may astound you.  The largest unexplored region of Earth is the ocean.  Beneath its churning surface, oceanographers have recently discovered the largest volcano in the world – perhaps in the solar system.

Find out what is known – and yet to be discovered – about the marine life of the abyss, and how a fish called the bristlemouth has grabbed the crown for “most numerous vertebrate on Earth” from the chicken.

Plus, the menace of America’s Cascadia fault, which has the potential to unleash a devastating magnitude 9 earthquake.

Follow Dr. Sager’s voyage back to Tamu Massif in Fall 2015.

A Big Hole in the Sun's Atmosphere


Source - Space Weather News for Nov. 21, 2016: http://spaceweather.com

RETURN OF A BIG CORONAL HOLE:  At the end of October, a hole in the sun's atmosphere lashed Earth's magnetic field with solar wind, sparking moderately-strong geomagnetic storms and almost a full week of Arctic auroras.  News flash:  It's back. The same "coronal hole" is turning toward Earth again. Forecasters expect the solar wind to reach Earth during the late hours of Nov. 22nd with minor G1-class geomagnetic storms possible on Nov. 23rd.

Big Picture Science for Monday November 21, 2016 - Weather Vain












Big Picture Science - Weather Vain

Everyone talks about the weather but no one does anything about it. Not that they haven’t tried.  History is replete with attempts to control the weather, but we’d settle for an accurate seven-day forecast.

Find out how sophisticated technology might improve accuracy, including predicting the behavior of severe storms.  Plus, the age when “weather forecast” was a laughable idea, but why 19th century rebel scientists pursued it anyway.

Also, a meteorologist who was falsely claimed to have “solved” the mystery of the Bermuda Triangle, and a climate scientist recounts the history of trying to control the weather, and the potential future of geoengineering.

Sunspot Cycle Plunges to Lowest Level in 5 Years


Source - Space Weather News for Nov. 17, 2016: http://spaceweather.com

SUNSPOT CYCLE AT LOWEST LEVEL IN 5 YEARS:  Sunspot counts have reached their lowest level in 5 years, a clear sign that Solar Minimum is approaching.  Contrary to popular belief, Solar Minimum is neither dull nor uneventful. Instead, space weather changes in interesting ways. Today's edition of Spaceweather.com lists some of the changes we can expect, including one that is happening right now: a measurable increase in atmospheric cosmic rays. Check it out.

Big Picture Science for Monday November 14, 2016 - Skeptic Check: Aliens - The Evidence



Big Picture Science - Skeptic Check: Aliens - The Evidence

Once again the aliens have landed … in theaters.  It’s no spoiler to say that the latest cinematic sci-fi, Arrival, involves extraterrestrials visiting Earth.

But for some folks, the film’s premise is hardly shocking.  They’re convinced that the aliens have already come.  But is there any proof that aliens are here now or that they landed long ago to, for example, help build the Egyptian pyramids?

Meanwhile, SETI scientists are deploying their big antennas in an effort to establish that extraterrestrials exist far beyond Earth.

Find out why – even if E.T. is out there – one scientist says making contact is a long shot, while another pioneering scientist involved in SETI remains hopeful  … and could aliens be responsible for the peculiar behavior of two star systems now making the news?

TARDY CME SPARKS BRIGHT AURORAS:  Arriving later than expected, a CME brushed against Earth's magnetic field on Nov. 9th, sparking a bright display of auroras seen mainly from Alaska. More auroras are in the offing as a new solar wind stream heads in our direction.  Estimated time of arrival: Nov. 11-12.

CME Impact Possible on Nov. 8th


Source - Space Weather News for Nov. 6, 2016: http://spaceweather.com

SUN HURLS PLASMA CLOUD TOWARD EARTH:  Yesterday, Nov. 5th, a magnetic filament on the sun became unstable and erupted. The blast opened a fiery canyon in the sun's atmosphere and hurled a CME toward Earth.  According to NOAA models, the plasma cloud could strike Earth's magnetic field on Nov. 8th, triggering G1-class geomagnetic storms and auroras around the poles.

Big Picture Science for Monday October 31, 2016 - Hidden History












Big Picture Science - Hidden History

ENCORE: Archeologists continue to hunt for the city of Atlantis, even though it may never have existed. But, what if it did? Its discovery would change ancient history. Sometimes when we dig around in the past, we can change our understanding of how we got to where we are.

We thought we had wrapped up the death of the dinosaurs: blame it on an asteroid. But evidence unearthed in Antarctica and elsewhere suggests the rock from space wasn’t the sole culprit.

Also, digging into our genetic past can turn up surprising – and sometimes uncomfortable truths – from ancestral origins to genes that code for disease. But do we always want to know?
