As Ganymede goes behind Jupiter, we see it through more and more of the giant planet’s atmosphere. We know how Gnaymede normally looks when it’s not being obscured by Jupiter, so we can observe it as it goes behind the planet to get a measurement of the atmospheric profile of Jupiter. This is especially handy to observe Jupiter’s very high, very thin haze layer that exists way above the visible cloud tops.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/D3E4AC52-0A23-452C-A3D7-11EBF40E752E/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
