How Deep Must Life Hide to Be Safe on Europa?
Jupiter's icy moon Europa is subject to constant and significant blasts of radiation. Researchers at NASA's Jet Propulsion Laboratory are now attempting to determine how deep life must lay beneath the moon's crust in order to survive.
Raindrops in Rock
A new study published in Nature from NASA's Exobiology and Evoluationary Biology program investigators and their colleagues looks at fossilized raindrops and what they indicate about conditions on the early Earth.
Follow the Uranium
Researchers funded by NASA's Astrobiology Institute and Exobiology Program have developed a novel geochemical tool that compares the partitioning of uranium isotopes from seawater into carbonates.
Amino Acid Alphabet Soup
For more than 3 billion years, organisms on Earth have relied on a standard set of 20 amino acids to build the proteins that carry out life's essential actions. But did it have to be this way?
Out of Thin Martian Air
Mars has lost an ocean's worth of water, but to find where it all went will take satellites and computer models working in conjunction.
