A new study led by The Australian National University (ANU) has found seawater cycles throughout the Earth's interior down to 2,900 km (1,800 miles), much deeper than previously thought, reopening questions about how the atmosphere and oceans formed.

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?

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.

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

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).

In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya, stayed open for three full winters before it closed.

Massive terrestrial planets, called "super-Earths," are known to be common in our galaxy, the Milky Way.

Earth's volatile elements (H, C, and N) are essential to maintaining habitable conditions for metazoans and simpler life forms.

In a new study published in Philosophical Transactions of the Royal Society B, scientists funded by the NASA Astrobiology Institute (NAI) advance a theory about life's origins based on the idea of "reservoir-mediated energy."
