These images show a subtle feature on Ceres called Kwanzaa Tholus. Kwanzaa, meaning first fruits in Swahili, is an African-American festival based on ancient African harvest celebrations, and takes place from December 26 to January 1. A tholus is a type of small mountain. Kwanzaa Tholus measures about 22 by 12 miles (35 by 19 kilometers) and is elevated about 2 miles (3 km) above its surroundings. Because the mountain does not rise sharply above the ground, it is difficult to see in the mosaic on the left, although a small crescent-shaped shadow stands out. The image on the right, which is an elevation map of the area, shows where Kwanzaa Tholus is more prominently. The rounded shape of Kwanzaa Tholus is typical of tholi (plural of tholus) in general, but is different than other examples found on Ceres (like Dalien Tholus) and Mars. This region is particularly rich in this type of feature The current Ceres map shows six named tholi and montes (slightly bigger mountains) in the region (

The Eridania basin of southern Mars is believed to have held a sea about 3.7 billion years ago, with seafloor deposits likely resulting from underwater hydrothermal activity. This graphic shows estimated depths of water in that ancient sea. A recent estimate of the total water volume of the ancient Eridania sea is about 50,000 cubic miles (210,000 cubic kilometers), about nine times the total volume of North America's Great Lakes. The map covers an area about 530 miles (850 kilometers) wide. This graphic was included in a 2017 report Ancient hydrothermal seafloor deposits in Eridania basin on Mars in Nature Communications. A reference bar indicating color coding of depth, from red, at right, showing depth of about 300 feet (100 meters) to black showing depth more than 10 times that depth.

This geological map covers a portion of Pluto's surface that measures 1,290 miles (2,070 kilometers) from top to bottom, and includes the vast nitrogen-ice plain informally named Sputnik Planum and surrounding terrain. The map is overlain with colors that represent different geological terrains. Each terrain, or unit, is defined by its texture and morphology -- smooth, pitted, craggy, hummocky or ridged, for example. How well a unit can be defined depends on the resolution of the images that cover it. All of the terrain in this map has been imaged at a resolution of approximately 1,050 feet (320 meters) per pixel or better, meaning scientists can map units with relative confidence. The various blue and greenish units that fill the center of the map represent different textures seen across Sputnik Planum, from the cellular terrain in the center and north, to the smooth and pitted plains in the south. The black lines represent the troughs that mark the boundaries of cellular regions in t

Hot and Cold

An annotated image of the surface of Mars, taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter (MRO) on May 30, 2014. The contrast has been enhanced in this image to better show the region where InSight landed on Nov. 26, 2018. The labels show the approximate position of NASA's InSight lander in Elysium Planitia. Overlaid on top are the direction of the vibrations detected by InSight's science instruments. The diagonal lines, faintly seen moving from upper left corner to the lower right corner of the image, show the paths of dust devils on the Martian surface. The vibrations recorded by InSight line up with the direction of the dust devil motion.

These images compare surface features observed by NASA's Cassini spacecraft at the Xanadu region on Saturn's moon Titan (left), and features observed by NASA's Galileo spacecraft on Jupiter's cratered moon Callisto (right).

On Earth, the longitude of the Royal Observatory in Greenwich, England is defined as the prime meridian, or the zero point of longitude. Locations on Earth are measured in degrees east or west from this position. The prime meridian was defined by international agreement in 1884 as the position of the large transit circle, a telescope in the Observatory's Meridian Building. The transit circle was built by Sir George Biddell Airy, the 7th Astronomer Royal, in 1850. (While visual observations with transits were the basis of navigation until the space age, it is interesting to note that the current definition of the prime meridian is in reference to orbiting satellites and Very Long Baseline Interferometry (VLBI) measurements of distant radio sources such as quasars. This International Reference Meridian is now about 100 meters east of the Airy Transit at Greenwich.) For Mars, the prime meridian was first defined by the German astronomers W. Beer and J. H. Mädler in 1830-32. They used a sm
