Ganymede, larger than even Mercury and Pluto, has an icy surface speckled with bright young craters overlying a mixture of older, darker, more cratered terrain laced with grooves and ridges; the large circular feature on the upper right, called Galileo Regio, is an ancient region of unknown origin; Ganymede is thought to have an ocean layer that contains more water than Earth and might contain life; like Earth’s Moon, Ganymede keeps the same face towards its central planet, in this case Jupiter; this image was taken about 20 years ago by NASA’s Galileo probe, which ended its mission by diving into Jupiter’s atmosphere in 2003; currently, NASA’s Juno spacecraft orbits Jupiter and is studying the giant planet’s internal structure, among many other attributes.

This image of Jupiter’s Great Red Spot and surrounding turbulent zones was captured by NASA’s Juno spacecraft. The color-enhanced image is a combination of three separate images taken on April 1 between 6:09 a.m. EDT (3:09 a.m. PDT) and 6:24 a.m. EDT (3:24 a.m. PDT). At the time the images were taken, the spacecraft was 15,379 miles (24,749 km) to 30,633 miles (49,299 km) from the tops of the clouds of the planet at a southern latitude spanning 43.2 to 62.1 degrees.

This composite image, derived from data collected by the JIRAM instrument aboard NASA’s Juno orbiter, shows the central cyclone at Jupiter’s north pole and the eight cyclones that encircle it. JIRAM collects data in infrared, and the colors in this composite represent radiant heat: the yellow (thinner) clouds are about 9 degrees Fahrenheit (minus 13 degrees Celsius) in brightness temperature and the dark red (thickest) are around minus 181 degrees Fahrenheit (83 degrees Celsius).

The early ocean known as Arabia (left, blue) would have looked like this when it formed 4 billion years ago on Mars, while the Deuteronilus ocean, about 3.6 billion years old, had a smaller shoreline; both coexisted with the massive volcanic province Tharsis, located on the unseen side of the planet, which may have helped support the existence of liquid water; the water is now gone, perhaps frozen underground and partially lost to space, while the ancient seabed is known as the northern plains.
