Main Point:

Scientists have developed first global geologic map of Ganymede, which is the largest moon in the solar system.

Study Further:

Ganymede:

Ganymede (moon) is present with Jupiter. It was discovered by Galileo about 400 years ago in January 1610.

It is the largest moon in the solar system having a diameter of about 3,280 miles (5,262 kilometers). It is larger than both planet Mercury – nearest planet to Sun – and dwarf planet Pluto – farthest planet to Sun.

Present Study:

The map of Ganymede is the first complete global geologic map of an icy, outer-planet moon and has been published by the U.S. Geological Survey representing different geological characteristics of Ganymede’s surface.

This map has been developed by a team of scientists led by Wes Patterson of the Johns Hopkins Applied Physics Laboratory, Laurel, Md., and Geoffrey Collins of Wheaton College, Norton, Mass., who utilized images taken from NASA’s Voyager (1979) and Galileo missions (1995–2003) in its making.

“By mapping all of Ganymede’s surface, we can more accurately address scientific questions regarding the formation and evolution of this truly unique moon,” Patterson said in a statement.

“Ganymede also shows features that are ancient alongside much more recently formed features, adding historical diversity in addition to geographic diversity,” Collins says.
