This is an artist's concept of NASA's New Horizons during its planned encounter with Pluto and its moon, Charon: the craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments would characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail; the spacecraft's most prominent design feature is a nearly 2.1-m dish antenna, through which it would communicate with Earth from as far as 7.5 billion km away.

Theta aurora over Antarctica. This image obtained in 1983 shows the auroral oval and a transpolar arc; the arc extends into the polar cap from local midnight, across the polar cap and joins with the auroral oval at local noon; motion of the transpolar arc in the dawn-dusk direction appears to be controlled by the direction of the interplanetary magnetic field along the dawn-dusk direction.

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.
