Where is Sol's family?
|
| |
Many if not all stars form with others in a stellar nursery, often from the shock of a nearby supernova, if my readiing is correct. So, why are we so reltively alone? Where did our suiblings go? And where is the remnant of our long-lost mother? I expect 4.5 billion years of stellar drift and galactic orbital mechanics... more »

Water or lack of on the moon
|
| |
Does anyone have predictions about the results of the LCROSS experiment? I think there is some water in those southern dark craters. But if the rocket stage had hit a serious ice deposit NASA would have announced preliminary results within a few hours. So I see two possibilities. 1- The rocket stage hit a bedrock outcrop. Would this explain the small amount of material ejected?... more »

LRO lava tube targets
|
| |
I noted from a (fairly old) LRO conference paper [1] that the LRO camera has a number of secondary targets lined up based on the results of Coombs' and Hawke's paper on potential intact lava tube sites.
