Ganymede's carbon dioxide gas was probably depleted in the past. [56] Ganymede's surface is a mix of two types of terrain: very old, highly cratered, dark regions and somewhat younger (but still ancient), lighter regions marked with an extensive array of grooves and ridges.
There are large variations in surface temperature over space and time on airless or near-airless bodies like Mars, which has daily surface temperature variations of 50–60 K. [18] [19] Because of a relative lack of air to transport or retain heat, significant variations in temperature develop. Assuming the planet radiates as a blackbody (i.e ...
Ganymede is composed primarily of silicate rock and water ice, and a salt-water ocean is believed to exist nearly 200 km below Ganymede's surface, sandwiched between layers of ice. [44] The metallic core of Ganymede suggests a greater heat at some time in its past than had previously been proposed.

Galileo Regio is a large, dark surface feature on Jupiter's moon Ganymede. [1] It is a region of ancient dark material that has been broken apart by tectonism and is now surrounded by younger, brighter material (such as that of Uruk Sulcus) that has been upwelling from Ganymede's interior. It is thought to be some 4 billion years old and is ...
Alaska's interior is well known for brutal cold and 54 years ago today its temperature plunged to America's all-time record low. The temperature hit minus 80 degrees at Prospect Creek Camp, Alaska ...
From the Earth's surface to the top of the stratosphere (50km) is just under 1% of Earth's radius. The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision-less.
