oceans of liquid water, making them an attractive breeding ground for life outside of our solar system.
Other factors also suggest Mars once had a much thicker atmosphere, such as evidence of persistent
presence of liquid water on the planet's surface long ago even though the atmosphere is too scant for liquid water to persist on the surface now.
Analysis of data also shows that Ceres has a water - ice mantle surrounding a rocky core, and that there may still be at least
pockets of liquid water beneath the surface, raising the prospect of potential habitability for microorganisms, as seemingly unlikely as that may sound for a world so far from the Sun.
«This is the best
evidence of liquid water on Mars in the present day,» says Georgia Institute of Technology scientist James Wray, co-author of a paper reporting the data published today in Nature Geoscience.
Until recently, that rule led scientists to think only in terms of places just like home: temperate, rocky planets with
bodies of liquid water on their surfaces.
Enceladus is subject to forces that heat a global ocean
of liquid water under its icy surface, resulting in its famous south polar water jets which are just visible below the moon's dark, southern limb.
A NOAA website on atmospheric rivers contains this fascinating statistic that illustrates just how much moisture can be transported by winds in the mid-to-upper atmosphere: «A strong atmospheric river transports an amount of water vapor roughly equivalent to 7.5 - 15 times the average
flow of liquid water at the mouth of the Mississippi River.»
