Ganymede: Torn Comet - Crater Chain
Title
Ganymede: Torn Comet - Crater Chain
Title
|
|
Explanation:
|
This striking line of 13 closely spaced craters [ http://photojournal
PIAGenCatalogPage.pl ?PIA01610 ] on Jupiter's moon Ganymede [ http://cass.jsc.nas
] was photographed by the Galileo spacecraft in 1997. The picture covers an area about 120 miles wide and the chain of craters cuts across a sharp boundary between dark and light terrain. What caused this crater chain? Remarkably, the exploration of the Solar System [ http://sse.jpl.nasa
], has shown that crater chains [ http://antwrp.gsfc.
] like this one are not unique [ http://neo.jpl.nasa
], though they were [ http://stardust.jpl
] considered mysterious until a dramatic object lesson was offered by comet Shoemaker-Levy 9. In 1994 many denizens of planet Earth [ http://antwrp.gsfc.
] watched as huge pieces of this torn comet [ http://antwrp.gsfc.
] slammed into Jupiter itself in a spectacular series of sequential impacts [ http://antwrp.gsfc.
]. It is very likely that similar torn comets from the early history of the Solar System are responsible for this and other crater chains [ http://astrosun.tn.
chain.html ].
