Lakes in Antarctica

Scientists are not complacent. We still have a lot to learn about the water cycle. The discovery of glacial lakes under the ice in Antarctica actively transporting water between reservoirs was a surprise. These lakes can be up to 3km beneath the ice sheets. The pressure of the ice above helps to melt the ice, forming lakes. ...

Water found on the moon

Scientists have confirmed the presence of water on the moon. Rather than occurring in rivers or lakes, water is found sparsely mixed amongst rocks. It's suggested the water came from comets, or the combination of incoming protons with oxygen. Jonathan Nally described the latest experiments where spacecraft will be sent ...
