Solar flare pulses at sun and Earth detected

Two recent studies show how solar flares exhibit pulses or oscillations in the amount of energy being sent out. Such research provides new insights on the origins of these massive solar flares and the space weather they produce. This is key information as humans and robotic missions venture out into the solar system, farther and farther from Earth.

Solar eruptions could electrify Martian moons

Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study. The study also considered electrical charges that could develop as astronauts transit the surface on potential human missions to Phobos.

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

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

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.
