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?

New research published today in the journal Astrobiology shows the vital role of oceans in moderating climate on Earth-like planets.

Roy Price first heard about the hydrothermal vents in New Caledonia's Bay of Prony a decade ago. Being a scuba diver and a geologist, he was fascinated by the pictures of a 38-meter-high calcite "chimney" that had precipitated out of the highly-alkaline vent fluid.

Researchers from the University of New Mexico and Northwestern University report evidence for potentially oceans worth of water deep beneath the United States. Though not in the familiar liquid form - the ingredients for water are bound up in rock deep in the Earth's mantle - the discovery may represent the planet's largest water reservoir.

Zunli Lu and Xiaoli Zhou, an assistant professor and Ph.D. student, respectively, in the Department of Earth Sciences, are part of an international team of researchers whose findings have been published by the journal Geology (Geological Society of America, 2014).

More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.

The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin of life.

Researchers from the University of Cambridge have published details about how the first organisms on Earth could have become metabolically active.

Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin?
