Interesting object on Jupiter's Moon Callisto
« on: August 02, 2014, 04:29:56 am »
Hi everyone,

I was looking at this pic made by the Galileo spacecraft of Jupiter's Callisto (moon) on September 17th, 1997. Of course it was quite a ways up (5700 miles) with a resolution of "90 meters (295 feet) per picture element". Most  likely an albedo artifact but it sure stands out.

Nice find Tom.  There's another "artefact" on the rim of the big crater at the bottom centre. The middle of the right-hand crater wall.

So there is! The craters are  very un-Moon like - with very smooth walls. I suppose the mix of rock and ice eventually froze after impact leaving a glassy finish.
