Ganymede

Ganymede

Ganymede Latest News

Magnetic and auroral evidence points to a vast ocean beneath Ganymede, but surface salts do not yet prove a direct connection through its roughly 150-kilometre ice shell.

About Ganymede

  • It is the largest of Jupiter’s satellites and of all the satellites in the solar system.   
  • It is the only moon known to possess its own magnetic field. 
  • Discovered by Galileo Galilei in 1610, Ganymede's name is derived from a figure in Roman mythology associated with the god Jupiter.  
  • It has a diameter of about 5,270 km, which makes it larger than the planet Mercury. 
  • It is situated about one million kilometers from Jupiter, exhibiting synchronous rotation, which means it always shows the same face to the planet. 
  • Ganymede’s relatively low density of 1.93 grams per cubic cm indicates that its composition is roughly half rock and half water ice by mass.  
  • Ganymede has a core of metallic iron, which is followed by a layer of rock that is topped off by a crust of mostly ice that is very thick. 
  • There are also a number of bumps on Ganymede's surface, which may be rock formations. 
  • It is believed that Ganymede has a saltwater ocean below its surface. 
  • A thin atmosphere surrounds Ganymede, containing hydrogen and possibly other compounds like carbon dioxide. 
  • Ongoing exploration, including missions like the recently launched Jupiter Icy Moons Explorer (JUICE), aims to deepen our understanding of Ganymede's geology, potential oceanic layers, and its role in the broader context of the solar system's formation and evolution.

Valles Marineris Latest News

A vastly larger outburst flood occurred on Mars during the Late Hesperian to Early Amazonian, when the breaching of paleolakes in Valles Marineris, the largest canyon system in the Solar System, unleashed a massive deluge.

About Valles Marineris

  • Valles Marineris, or Mariner Valley, is a vast system of interconnected canyons on the planet Mars.
  • The system was discovered during, and named for, the Mariner 9 mission in 1971.
  • The canyons extend in an east-west direction for roughly 4,000 km just south of the equator. 
  • By comparison, Earth’s natural wonder, the Grand Canyon, is only 446 km long.
  • It is one of the larger canyons in the solar system.
  • It spans about 20 percent of the entire circumference of Mars. 
  • Individual canyons are typically 200 km across and have walls 2–5 km high.
  • At the centre of the system, several canyons merge to form a depression 600 km across and 9 km deep.
  • The canyon system contains a number of different features that give clues to its formation. 
    • Some of the canyon walls appear to be fault scarps that formed as a result of crustal movement along faults radiating from the Tharsis rise, an enormous volcanic bulge to the northwest. 
    • Erosion, however, has also played a significant role in canyon formation, as indicated by deep gullies cut in the walls.
    • In places, the canyons contain thick sedimentary sequences that may have been deposited in lakes that formerly occupied the canyons. 
    • These lakes later may have drained catastrophically to the east, where there is evidence of large floods.
