FOXSI Mission Will View The Sun With X-Ray Vision
Without special instrumentation, the Sun looks calm and inert. But beneath that placid façade are countless miniature explosions called nanoflares. These small but intense eruptions…
New Research Suggests Solar Eruptions Have Interesting Shapes After All
As the saying goes, everything old is new again. While the common phrase often refers to fashion, design, or technology, scientists at the University of…
SWEAP Investigation Will Directly Measure Ionized Gas in the Solar Atmosphere
When NASA’s Parker Solar Probe launches into space from the Kennedy Space Center, it will begin its journey to the Sun, our nearest star. The…
Ancient Blue Crystals Reveal What the Early Sun Was Like
Our Sun’s beginnings are a mystery. It burst into being 4.6 billion years ago, about 50 million years before the Earth formed. Since the Sun…
Parker Solar Probe Will Face Several-Million-Degree Fahrenheit Temperatures
