NASA’s EUNIS Detects Evidence Supporting Coronal Heating Theory

Dr Adrian Daw of NASA’s Goddard Space Flight Center and his colleagues have gathered some of the strongest evidence to date to explain what makes the Sun’s outer atmosphere so much hotter than its surface. Image credit: NASA / SDO.

Strong new evidence supports a theory that the Sun’s corona is heated by tiny explosions called nanoflares. Dr Adrian Daw of NASA’s Goddard Space Flight Center and his colleagues have gathered some of the strongest evidence to date to explain what makes the Sun’s outer atmosphere so much hotter than its surface. Image credit: NASA / SDO. The Sun’s visible surface, called the photosphere, is some 6,000 Kelvins, while the corona regularly reaches...

The moons of our Solar System are brimming with unusual landscapes. However, sometimes they look a little more familiar, as in this new radar image from the Cassini orbiter. The image shows dark streaks carved into dunes reminiscent of those we might find on a beach on Earth, or raked with flowing lines in a Japanese Zen garden — but this scene is actually taking place on Saturn’s moon Titan. While our sand is composed of silicates, the ‘sand’ of these alien dunes is formed from grains of organic materials about the same size as particles of our beach sand. The small size and smoothness of these grains means that the flowing lines carved into the dunes show up as dark to the human eye. While previous images have spotted these eerily familiar patterns on Titan's dunes, this new image (colorized) shows them in greater detail. The image was obtained by Cassini's radar mapper on July 10, 2013. The vertical seam near the center is an artifact of radar image data processing. Image credit: NASA / JPL-Caltech / Sci-News.com.

This view from Curiosity rover’s Mastcam shows a network of 2-tone mineral veins at the Garden City area on lower Mount Sharp, Mars. This is a mosaic combining 28 images taken with Mastcam’s right-eye camera, which has a telephoto lens with a focal length of 100 mm. The component images were taken on March 18, 2015, during the 929th Martian day of Curiosity’s work on the Red Planet. The color has been approximately white-balanced to resemble how the scene would appear under daytime lighting conditions on Earth. Image credit: NASA / JPL-Caltech / MSSS.

This mosaic image from the NASA/ESA/ASI Cassini-Huygens spacecraft is centered at 9 degrees north latitude, 254 degrees west longitude. The image was acquired at a distance of about 57,800 km from Rhea. This image represents one of the highest resolution color views of the icy moon released to date, and consists of multiple images from Cassini’s narrow-angle camera (NAC) with data from the wide-angle camera used to fill in areas where NAC data was not available.
