Ganymede Is Jupiter’s Melted, Battered Child

Scientists have envision out a potential reason for the departure between Jupiter ’s two Moon : One of them has been abused so bad that its metaphorical chocolate chips have sink to the bottom of its ice cream carton . Or something .

For decades , scientists have wondered why Ganymede and Callisto look so different , despite their similar composition and size . But unexampled enquiry carried out at the Southwest Research Institute suggests that the result has to do with what happened to both moons over 3 billion days ago . harmonise to Dr. Amy Barr , who ran the study with Dr. Robin Canup , Ganymede ’s closer propinquity to Jupiter meant that it see more action during the Late Heavy Bombardment :

Impacts during this geological period melted Ganymede so thoroughly and deep that the warmth could not be speedily removed . All of Ganymede ’s rock drop down to its center the same style that all the hot chocolate chips sink to the bottom of a melted carton of shabu cream . Callisto receive fewer impacts at lower velocities and avoided complete melting .

Barr and Canup have evencreated a motion-picture show to explain the difference . Barr is appropriately aroused about the find :

standardized to Earth and Venus , Ganymede and Callisto are Gemini , and sympathize how they were born the same and grew up to be so different is of tremendous interest group to planetary scientist … Our study establish that Ganymede and Callisto record the fingermark of the early evolution of the solar system , which is very exciting and not at all require .
