The Caspian Hare Posted August 21, 2018 #1 Share Posted August 21, 2018 https://www.jpl.nasa.gov/news/news.php?feature=7218 Quote In the darkest and coldest parts of its polar regions, a team of scientists has directly observed definitive evidence of water ice on the Moon's surface. These ice deposits are patchily distributed and could possibly be ancient. At the southern pole, most of the ice is concentrated at lunar craters, while the northern pole's ice is more widely, but sparsely spread. Link to comment Share on other sites More sharing options...
lightly Posted August 21, 2018 #2 Share Posted August 21, 2018 Fascinating ! The link also mentions that water has been detected beneath the moon's surface. I never knew that. Link to comment Share on other sites More sharing options...
paperdyer Posted August 21, 2018 #3 Share Posted August 21, 2018 Perhaps there is an underground well or two somewhere. I wouldn't have thought the Moon had enough of an atmosphere to keep water in the open, even in shaded areas. Link to comment Share on other sites More sharing options...
Bunzilla Posted August 21, 2018 #4 Share Posted August 21, 2018 I remember maybe ten or so years ago, when they were trying to claim that water was super rare and it would be hard to find anywhere. Now we're finding it everywhere. Link to comment Share on other sites More sharing options...

Now we're finding it everywhere. Not true, it has always been known that water is common. What was considered rare (and to an extent still is) is finding the conditions for water to exist in LIQUID form. Link to comment Share on other sites More sharing options...

It doesn't have enough of an atmosphere to keep water in LIQUID form. At low pressures water sublimes, meaning it changes directly from a solid to a gases form (or vice versa) without passing through the liquid form. If the temperature remains low enough, as it does in these craters, then the ice will not sublime. Else where the ice has turned to vapour and, because of the moon's low gravity field, escaped into space. 1 Link to comment Share on other sites More sharing options...

taniwha Posted August 22, 2018 #9 Share Posted August 22, 2018 Just now, seanjo said: Other way round, The Moon was formed from debris that was expelled when the Earth was hit by a large object. Not sure if that's been proved. Somedays I wonder if it has snowed on the moon its that brilliant white, sure would of looked amazing if it was once entirely covered in ice though.

According to another theory, the Moon-Mother singled out the Earth in a hot state and gave her almost all its life principles so that evolution could develop physical forms on earth. The same thing happened with the satellites of other planets. Edited August 22, 2018 by Coil Link to comment Share on other sites More sharing options...

RoofGardener Posted August 22, 2018 #13 Share Posted August 22, 2018 (edited) I don't understand why ICE is interested in the moon ? Surely there can't be any illegal immigrants there ? Edited August 22, 2018 by RoofGardener Link to comment Share on other sites More sharing options...

I remember them talking about it existing at the poles. " The result comes from an instrument on India's Chandrayaan-1 spacecraft, which explored the Moon between 2008 and 2009.

Previous evidence was not direct proof, ice was the most likely explanation but the evidence was not unequivocal. These latest results have directly detected water ice and so the results are unequivocal. The presence of ice at the moon's poles has moved from being hypothesis to fact.

Still, there certainly has been a lot of liquid water discovered since then. Just not in this case. At least, that we know of... I wouldn't have expected to find liquid water on Mars either. So who knows. Link to comment Share on other sites More sharing options...
