>> Skywatchers across the US are in for a treat. On August 21st, for the first time in almost a century, a total solar eclipse will reach across the country, plunging the strip, 70 miles wide, into darkness. NASA's Dr. Nicholeeen Viall says she's excited.>> What's super cool is for two minutes, all of a sudden in the middle of the day, it goes dark like it's a moonlit night.
>> Weather permitting, the moon silhouette will be visible as it passes across the country from Lincoln Beach, Oregon, to McClellanville, South Carolina. And for those wearing safety glasses or using a pinhole camera, the sun's outer atmosphere known as the corona will be on full display.>> The solar corona is very hot, millions of degrees, many orders of magnitude hotter than the surface below it, the surface of the sun.
That's really weird. That'd be like, if you walked away from a fireplace and it kept getting hotter. So we wanna understand why that is.>> A potentially hot day for science and a cool experience for everyone else.
