10/13/2016 – Ephemeris – Europa appears to have water geysers like Enceladus

October 13, 2016

Ephemeris for Thursday, October 13th. The Sun will rise at 7:56. It’ll be up for 11 hours and 4 minutes, setting at 7:00. The Moon, 3 days before full, will set at 5:48 tomorrow morning.

On September 26th NASA announced that the Hubble Space Telescope has confirmed earlier observations that Europa, Jupiter’s second large moon is venting water vapor. It is pretty much known that Europa has a moon girdling ocean many tens of miles below its icy surface. The surface is devoid of craters, showing that there is some interaction with the ocean below and the cracks we see on the surface. Having plumes or geysers will allow spacecraft and landers to sample the ocean below without having to drill down to the ocean. NASA has okayed a mission to Europa. This could change the mission and instruments and maybe add a lander to probe the geysers, though first the have to find them.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Addendum
