Science AMA Series: We’re NASA scientists. Ask us anything about the science of the Aug. 21 total solar eclipse!

See the source article by following the link below:

On Aug. 21, 2017, all of North America will have the chance to see a partial solar eclipse. Along a narrow, 70-mile-wide track called the path of totality, the Moon will totally block the Sun, revealing the Sun’s comparatively faint outer atmosphere – the corona. Total solar eclipses like this are a rare chance for solar scientists to study this region of the Sun, since we can’t ordinarily see it from the ground or with satellite instruments. The sudden blocking of light also gives Earth scientists a rare chance to track how Earth’s atmosphere responds to the Sun’s radiation.

Noah Petro

I first became interested in Geology as a student at Fox Lane High School in Bedford, NY. It was while I was a student at Bates College that I was introduced to the field of planetary geology. Following my PhD work at Brown University I came to NASA Goddard as a NASA Post-Doc.

Alexa Halford

I am a contractor at NASA Goddard. Throughout my education I have been lucky to work at JPL NASA looking at Uranus's moons and study Saturn on the Cassini mission at the South West Research Institute. Today I stick a bit closer to home studying the Earth's magnetic field and its space weather phenomena.

Mitzi Adams

I am a solar scientist for NASA’s Marshall Space Flight Center (MSFC), where I study the magnetic field of the Sun and how it affects the upper layer of the solar atmosphere, the corona. With a professional interest in sunspot magnetic fields and coronal bright points, friends have labelled me a “solar dermatologist”.

Bill Cooke

The head of NASA's Meteoroid Environment Office, I help NASA in placing meteoroid protection on spacecraft and construct meteor shower forecasts for unmanned space vehicles and the International Space Station. While a graduate student at the University of Florida, I worked on instruments flying on board balloons, the Space Shuttle, Giotto (European mission to Halley's Comet), and LDEF. After obtaining my PhD in Astronomy, I came to work at Marshall Space Flight Center as a member of the Space Environments Team, where I became an acknowledged expert in meteors and meteoroids. I am one of the many NASA astronomers interacting with the public on the upcoming solar eclipse.
