Earth
About 71% of Earth is covered by ocean. Its longest mountain range lies underwater, stretching through the Arctic and Atlantic oceans.

Discovery field notes
Moon
Water ice exists on the Moon. The highest concentrations occur in dark craters near the poles, where sunlight cannot easily reach.
https://science.nasa.gov/moon/facts/Mars
Mars is home to Olympus Mons, the largest volcano in the solar system. This giant is a reminder of a once volcanically active world.
https://science.nasa.gov/mars/facts/Jupiter
Jupiter’s Great Red Spot is a giant storm bigger than Earth. Juno measurements constrain its depth to about 500 kilometers below the cloud tops.
https://science.nasa.gov/jupiter/jupiter-facts/Saturn
Saturn’s rings are made of billions of chunks of ice and rock. Their particles range from tiny grains to pieces as big as a house, and sometimes larger.

Earth · Eye of the Sahara
The Richat Structure in Mauritania looks like a giant crater. It is actually an eroded geologic dome: different rock layers wore away at different rates, leaving concentric ridges.
NASA primary sourceRegional marker: 21.1° latitude, -11.4° east-positive longitude. Approximate region. Open the NASA field note for a close-up; this globe does not resolve the rings in detail.
Earth · The hidden mountain range
About 71% of Earth is covered by ocean. Its longest mountain range lies underwater, stretching through the Arctic and Atlantic oceans.
NASA primary sourceMoon · Tycho crater
Bright streaks radiate from Tycho across the Moon’s near side. They are material thrown out by the impact. Over time, exposure to the space environment darkens these rays until they fade into the background.
NASA primary sourceRegional marker: -43.3° latitude, -11.4° east-positive longitude. Approximate crater center on a color-adjusted composite map. Lighting is illustrative.
Moon · Sea of Tranquility
Neil Armstrong and Buzz Aldrin landed Apollo 11 in Mare Tranquillitatis on July 20, 1969. They spent about 21.5 hours on the lunar surface and collected roughly 21.5 kilograms of samples.
NASA primary sourceRegional marker: 0.7° latitude, 23.5° east-positive longitude. Approximate landing region. The lander and footprints are far too small to see on this globe.
Mars · Olympus Mons
Mars is home to Olympus Mons, the largest volcano in the solar system. This giant is a reminder of a once volcanically active world.
NASA primary sourceRegional marker: 18.7° latitude, -133.8° east-positive longitude. Approximate volcano center. This is a surface map on a sphere, not raised 3D terrain.
Mars · Valles Marineris
Valles Marineris is a vast Martian canyon system about 3,870 kilometers long. NASA compares its length to the distance from California to New York.
NASA primary sourceRegional marker: -14° latitude, -59° east-positive longitude. A broad representative region of a long canyon system. Terrain relief is not modeled.
Jupiter · The Great Red Spot
Jupiter’s Great Red Spot is a giant storm bigger than Earth. Juno measurements constrain its depth to about 500 kilometers below the cloud tops.
NASA primary sourceSaturn · A world of rings
Saturn’s rings are made of billions of chunks of ice and rock. Their particles range from tiny grains to pieces as big as a house, and sometimes larger.
NASA primary sourceMarkers are coarse editorial regional centers checked against the credited composite maps, not independently certified survey coordinates. Jupiter and Saturn stories have no fixed surface coordinates. Camera-relative lighting keeps regions readable; it is not the calculated Sun direction.

These are color-adjusted composites based on NASA imagery and elevation data, with reconstructed terrain in some unmapped areas. They are not live photographs, exact current weather, or a guarantee of true color. Jupiter and Saturn maps show cloud tops. The lighting, ring tilt, surface orientation and travel are illustrative, not calculated from the current ephemeris. Earth clouds are available in High quality.
Lite mode uses a simplified Natural Earth map (public domain). Original procedural illustrations are retained only as a labeled fallback if a texture fails to load. Natural Earth terms. No external 3D models or font files are redistributed. Texture source and checksum register.
Position calculations
Astronomy Engine (MIT) computes the selected body's light-time-corrected, geocentric J2000 equatorial vector. Distances are converted from AU to kilometers. RA and declination describe that same vector. No observer location is collected. Positions do not determine the illustrative scene layout.
