This will be where we talk about the data as it arrives over the next 20 months or so.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The interesting light color at the "neck" might suggest there could be slight movement between the 2 component bodies, and "grinding" of relatively fresh ice in that area...

Anybody know which direction is "up" and which is "down" at the neck of a contact binary like UT? How did / could that change as the binary spun-down? |
