Can we breathe on Ganymede?
Ganymede lies within the intense radiation belt of Jupiter. The lack of a protective atmosphere would expose a human to lethal doses of radiation.
Is there oxygen on Ganymede?
Ganymede has a thin oxygen atmosphere that includes O, O2, and possibly O3 (ozone). Ganymede’s discovery is credited to Galileo Galilei, the first to observe it, on January 7, 1610.
Can we live in Ganymede?
It takes Ganymede about seven Earth-days to orbit Jupiter. However, it is too thin to support life as we know it; it is unlikely that any living organisms inhabit Ganymede. Magnetosphere: Ganymede is the only satellite in the solar system to have a magnetosphere.
How is Ganymede heated?
Researchers believe there is tidal heating on Ganymede, although to a much smaller degree than on Io and Europa. This heat could drive some tectonic activity and provide one of the necessary conditions for life to emerge: a source of energy.
Does Io have an atmosphere?
Sulfur dioxide is the primary constituent of a thin atmosphere on Io. It has no water to speak of, unlike the other, colder Galilean moons. Data from the Galileo spacecraft indicates that an iron core may form Io’s center, thus giving Io its own magnetic field.
Why does Ganymede not have an atmosphere?
This heat drove off all the water within Io and most of it from Europa. Ganymede and Callisto kept their ice, but they still got hot enough to lose most of the gas that might otherwise have been trapped in their icy interiors. Consequently, none of the Galilean moons ended up with a substantial atmosphere.
How do we know that Ganymede has water?
Astronomers have used archival datasets from the NASA/ESA Hubble Space Telescope to reveal the first evidence for water vapor in the atmosphere of Jupiter’s moon Ganymede, the result of the thermal escape of water vapor from the moon’s icy surface. Nevertheless, where there is water there could be life as we know it.
What is the centripetal acceleration of Ganymede?
(ii) the centripetal acceleration of Ganymede in its orbit, r = 1.07 × 106 km = 1.07 × 109 m. (iii) the mass of Jupiter.
Is there an underground ocean on Ganymede?
Scientists have also found strong evidence of an underground ocean on Ganymede. Ganymede is named for a boy who was made cupbearer for the ancient Greek gods by Zeus – Jupiter to the Romans. Ganymede has three main layers.
What is special about the moon Ganymede?
Ganymede is the largest moon in our solar system and the only moon with its own magnetic field. The magnetic field causes auroras, which are ribbons of glowing, electrified gas, in regions circling the moon’s north and south poles.
What is the relationship between Jupiter and Ganymede?
Outward from Jupiter, it is the seventh satellite and the third of the Galilean moons, the first group of objects discovered orbiting another planet. Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively.
When was Ganymede discovered and by whom?
Discovery. Ganymede was discovered by Galileo Galilei on Jan. 7, 1610. The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth. The discovery of the four Galilean satellites eventually led to the understanding that planets in our solar system orbit the sun,…
