The Astrobiological Periodic Table

The Astrobiological Periodic Table has been developed by astrobiologist Charles Cockell.

Self-organizing processes in chemical reaction/precipitation systems can lead to a variety of complex structures, including chemical gardens and inorganic membranes.

DNA is synonymous with life, but where did it originate? One way to answer this question is to try to recreate the conditions that formed DNA's molecular precursors.

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.

The self-organization properties of DNA-like molecular fragments four billion years ago may have guided their own growth into repeating chemical chains long enough to act as a basis for primitive life, says a new study by the University of Colorado Boulder and the University of Milan.

Learn about planets beyond our solar system, far-flung missions and possible life in the cosmos at "(un)Discovered Worlds," a one-day Cornell University space sciences conference, May 9, to inaugurate the new Institute for Pale Blue Dots.

Atmospheric chemical disequilibrium has been proposed as a method for detecting extraterrestrial biospheres from exoplanet observations.

NASA seeks a new Director for the NASA Astrobiology Institute (NAI). The ideal candidate will be an internationally recognized scientist with proven experience in leading or managing large interdisciplinary research programs or projects, possessed with a vision for leading the Institute into the future.

Astrobiology and the Search for Extraterrestrial Life by The University of Edinburgh. Self-paced online course.

Old Dominion University faculty member Nora Noffke has made a name for herself as a geobiologist during the past decade by producing sedimentary evidence that prokaryote biofilms existed on Earth billions of years ago.

NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill.

New research published today in the journal Physical Review Letters describes how recreating isotopes that occur when a star explodes, can help physicists understand where life-supporting elements may be found in space.

NASA Video: Europa: Ocean World

Scientists believe there is an ocean hidden beneath the surface of Jupiter's moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity's most profound questions.

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future.

NASA's Astrobiology Institute (NAI) announced that the SETI Institute has been selected as a new member of theNAI for a 5-year research program, "Changing Planetary Environments and the Fingerprints of Life."

NASA has awarded five-year grants totaling almost $50 million to seven research teams nationwide to study the origins, evolution, distribution, and future of life in the universe.

In 1930, Albert Einstein was asked for his opinion about the possibility of life elsewhere in the universe. "Other beings, perhaps, but not men," he answered. Then he was asked whether science and religion conflict. "Not really, though it depends, of course, on your religious views."

Water On Earth Is Older Than Our Sun

A pioneering new study has shown that water found on Earth predates the formation of the Sun -- raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy.

NASA's Exposing Microorganisms in the Stratosphere (E-MIST) experiment launched to the Earth's stratosphere on the exterior of a giant scientific balloon gondola at about 8 a.m. MST on Aug. 24 from Ft. Sumner, New Mexico.
