By monitoring auroral activity on exoplanets, we may be able to infer the presence of water on or within an exoplanet.
Revealing water in significant quantities on the Moon could truly be a turning point in space exploration.
We do care about planets like the Earth because by now we understood that life as a chemical system really needs a smaller planet with water and with rocks and with a lot of complex chemistry to originate, to emerge, to survive.
The temperatures required for caramelization and browning almost always far exceed the boiling point of water. So the presence of water on the surface of a food, or on the bottom of a pan, is a signal that browning can't yet occur.
The more we look at the kinds of soils and the nature of the atmosphere and the polar caps, it all adds up to tell us that some liquid, which we very much believe was water, did flow in abundance on Mars in the past.
Russia perhaps is still entertaining the possibility that the moons of Mars might have access to ice or water.
I love water - I'm an Aquarius, but that has nothing to do with it - and I've never been away from water in any place.
There should be a water table on Mars.
From a scientific point of view, we now know that the water is interlaced with the lunar soil in many locations, perhaps as remnants of comet collisions with the lunar surface.
