How scientists used NASA data to predict the corona of the Aug. 21 Total Solar Eclipse

more »
When the total solar eclipse swept across the United States on Aug. 21, 2017, NASA satellites captured a diverse set of images from space. But days before the eclipse, some NASA satellites also enabled scientists to predict what the corona -- the Sun's outer atmosphere -- would look like during the eclipse, from the ground. In addition to offering a case study to test our predictive abilities, the predictions also enabled some eclipse scientists to choose their study targets in advance.

Solar research: NASA sounding rocket instrument spots signatures of long-sought small solar flares

more »
Like most solar sounding rockets, the second flight of the FOXSI instrument -- short for Focusing Optics X-ray Solar Imager -- lasted 15 minutes, with just six minutes of data collection. But in that short time, the cutting-edge instrument found the best evidence to date of a phenomenon scientists have been seeking for years: signatures of tiny solar flares that could help explain the mysterious extreme heating of the Sun's outer atmosphere.
