  1. At a point midway between Andromeda and the Milky Way, you could see both of those galaxies and the M33 galaxy as fuzzy patches of light, with both Andromeda and Milky Way galaxies being brighter than Andromeda is as seen fro Earth. But in the voids between superclusters, you should be far enough away from all galaxies that no galaxy would be visible to the naked eye.

    One of the cool things about the FH launch last night -- if you watch SES-3, it actually shows the velocity decreasing as the burn begins. That's because speed was being measured relative to the ground station in a geocentric coordinate system.

    Ah! I didn't catch the SES-3 burn itself. When I checked back in they were releasing the satellites, and the velocity reading at that time looked way too low (I thought the display or units must be faulty). But geocentric coordinates with velocity relative to surface makes it all clear. Thanks!
