Friday, 7 August 2020 (2 hours ago) Image data reanalysis has revealed that … Huge ring-like structure on Ganymede's surface may have been caused by violent impact Friday, 7 August 2020 ( 2 hours ago ) Image data reanalysis has revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Jupiter's moon Ganymede. The detection of The permanent magnetic moment carves a part of space around Ganymede, creating a tiny The interaction between the Ganymedian magnetosphere and Jovian In addition to the intrinsic magnetic moment, Ganymede has an induced dipole magnetic field.Given that Ganymede is completely differentiated and has a metallic core,Despite the presence of an iron core, Ganymede's magnetosphere remains enigmatic, particularly given that similar bodies lack the feature.The radiation level at the surface of Ganymede is considerably lower than at Europa, being 50-80 mSv (5-8 rem) per day, an amount that would cause severe illness or death in human beings exposed for two months.After formation, Ganymede's core largely retained the heat accumulated during accretion and differentiation, only slowly releasing it to the ice mantle.Several probes flying by or orbiting Jupiter have explored Ganymede more closely, including four flybys in the 1970s, and multiple passes in the 1990s to 2000s. The paper for this study was published online in Icarus on July 15.Many furrows, or trough formations, have been previously observed on the surface of Ganymede, one of Jupiter’s moons.The research group comprehensively reanalyzed image data of Ganymede’s surface obtained by NASA’s Voyager 1, Voyager 2 and Galileo spacecraft.The results revealed that almost all of these furrows on the surface of Ganymede appear to be in concentric rings centered at a single point, indicating that this global multiring structure may be the remains of a giant crater.The radial extent of the multiring measured along the satellite’s surface is 7800km. Schéma en coupe de Ganymède, mettant en évidence sa structure interne. An enormous amount of heat is necessary to form these differentiated layers. Its diameter of 5,268 km is 0.41 times that of The Ganymedian surface albedo is very asymmetric; the leading hemisphereGanymede's surface is a mix of two types of terrain: very old, highly The heating mechanism required for the formation of the grooved terrain on Ganymede is an unsolved problem in the Cratering is seen on both types of terrain, but is especially extensive on the dark terrain: it appears to be saturated with impact craters and has evolved largely through impact events.One significant feature on Ganymede is a dark plain named Ganymede also has polar caps, likely composed of water frost.

In particular, the researchers focused on furrows, tectonic troughs that are believed to be the oldest surface features on the satellite. Ring-like Structure on Ganymede May Have Been Caused by a Violent Impact (Study) Scientists from Kobe University and the National Institute of Technology, Oshima College have conducted a detailed reanalysis of image data from Voyager 1, 2 and Galileo spacecraft in order to investigate the orientation and distribution of the ancient tectonic troughs found on […] If the file has been modified from its original state, some details may not fully reflect the modified file.I, the copyright holder of this work, hereby publish it under the following license:The following pages on the English Wikipedia use this file (pages on other projects are not listed):(SVG file, nominally 2,800 × 1,700 pixels, file size: 1.2 MB)Commons is a freely licensed media file repository. Ganymede׳s density structure constrains the radius of its iron core and silicate mantle consistent with those of the overlying materials. In the meantime, to ensure continued support, we are displaying the site without styles In the cases of Io, Europa and Callisto, these are identical to the Latin, but the Latin form of Ganymede is The current Laplace resonance is unable to pump the orbital eccentricity of Ganymede to a higher value.There are two hypotheses for the origin of the Laplace resonance among Io, Europa, and Ganymede: that it is primordial and has existed from the beginning of the Solar System;Ganymede is the largest and most massive moon in the Solar System.
