Tempestuous Ariel

  Nov 3, 2015 Another moon with unmistakable signs of electric discharge impacts. The moon Ariel is pockmarked with craters ranging from five to ten kilometers across—almost undetectable in the image above—however, a few craters measuring 20-30 kilometers across are visible. The crater dimensions might seem small, but considering Ariel’s equatorial…

Star Wires

  Oct 30, 2015 Galaxies are threaded through with filaments. The Herschel Space Observatory was launched with the largest spaceborne mirror ever constructed: 3.5 meters in diameter. Herschel was set to orbit around LaGrange point L2 in July 2009, to protect its liquid helium-cooled infrared detectors. However, Herschel’s helium coolant…

Resolving Rhea

  Oct 29, 2015 Rhea bears examination in light of electrical theories. Rhea is one of Saturn’s medium-sized moons, second only in size to Titan, with a mean diameter of 1528 kilometers. The entire visible surface of Rhea is covered in craters, making it a candidate for the most heavily cratered…
