Astronomers have long held that water -- two hydrogen atoms and an oxygen atom -- was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and not by the Big Bang itself.

Our Ocean's Cosmic Origin

A new study published in Science looks beyond the question of whether Earth's oceans can be traced to comets or other objects from space, and instead asks the question: where did the water in comets come from?

As NASA missions explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways.

Habitability of Water Worlds

There are four different stable climate states for pure water atmospheres, as might exist on so-called "waterworlds".

"Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?"

NASA's Cassini spacecraft has provided scientists the first clear evidence that Saturn's moon Enceladus exhibits signs of present-day hydrothermal activity which may resemble that seen in the deep oceans on Earth.

In this paper we present a series of models for the deep water cycle on super-Earths experiencing plate tectonics.

Super-Earths Have Long-Lasting Oceans

For life as we know it to develop on other planets, those planets would need liquid water, or oceans.

Life on an Aquaplanet

An MIT study finds an exoplanet, tilted on its side, could still be habitable if covered in ocean.

A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system?
