✧ A SMALL DISCOVERY

OUR BLUE HOME01 / 05

An ocean hiding mountains.

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

REAL SCIENCE, A LITTLE PERSPECTIVE

Earth · our reference world.

Regional pins use approximate east-positive coordinates. Jupiter and Saturn stories have no fixed surface pin. Close views show composite maps, not lander-scale detail.

Illustrative journey: sizes, spacing, lighting, surface appearance and travel time are not to scale. Calculated positions are reported separately, never used as this scene’s layout.

Position calculation details

Select another world for its calculated position.

Earth-centered J2000 equatorial coordinates, light-time corrected, without aberration. Not a local sky map or navigation tool.

Stay curious.

Wonder Atlas is a small invitation to look a little closer. Phase 1 is an independent, English-first prototype with no accounts, tracking or API keys. Your found field notes are remembered on this device.

JavaScript is disabled. Explore these NASA sources:

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

Moon: Water ice exists on the Moon. The highest concentrations occur in dark craters near the poles, where sunlight cannot easily reach.

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.

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.

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.

Travel field notes:

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.

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.

Moon · 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.

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.

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.

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.

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.

Saturn · 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.
