NEW CHANNEL! http://youtube.com/sciencium For a long time we thought the Moon was completely dry, but it turns out there are actually three sources of lunar water. Thanks to Google Making...

Is there water on the MoonThe obvious answer seems to be No. because during a dayon the Moon, which lasts 2 earth weeks,the temperature on the lunar surfacegets up to 123 degrees celsius,which would be enough to boil away any waterif the Moon had an atmosphere like Earth,which it doesn't.And the reason that it doesn'tis because the Moon's gravity is weak,just a sixth of Earth's gravity, which meansit can't hold onto light fast movingmolecules like water. Anything goingfaster than 2.4 kilometers per secondthe Moon's escape velocity is gone.But that might sound pretty quick, but at anygiven temperature there are always asmall number of molecules goingsignificantly faster than the average.On the Moonthese molecules flap into sp...
