Seeking Salt That Surfaces from Europa’s Hidden Ocean
Irradiation-induced color changes in sodium chloride could reveal whether it came from ocean water mixing with surface water, a key component of the moon’s potential to support life.
Tests Indicate Which Edible Plants Could Thrive on Mars
An undergraduate experiment grew vegetables and herbs in simulated Martian soil under Mars-like reduced daylight. The tasty results suggest that Mars colonists could farm their own produce.
Clues Found That Earth May Have a Thermostat Set to “Habitable”
Weathering of rocks can control Earth’s temperature over geologic timescales, new geochemical data suggest.
Could a Newfound Molecule on Titan Be a Building Block for Life?
The discovery of vinyl cyanide in the atmosphere of Saturn’s moon Titan has huge implications for life—but not as we know it.
New Instrument May Aid Search for Extraterrestrial Life
For 2 weeks on the Greenland ice cap, scientists tested an instrument that might help us find life on icy moons with oceans beneath their crusts.
Hydrogen Molecules Hint at Habitability of Enceladus's Ocean
Scientists suggest that the hydrogen could be evidence of hydrothermal activity on the ocean floor of Saturn's sixth largest moon.
Scientists Spot Organic Molecules on Ceres
The presence of organic material on Ceres raises new questions about its internal evolution and potential for hosting past or present life.
New Report Details How NASA Could Land on Europa
A team of scientists laid out extensive details about a hypothetical future landing mission to find life on Jupiter's moon.
Seeking Signs of Life and More: NASA’s Mars 2020 Mission
The next Mars rover will be able to land near rugged terrain, giving scientists access to diverse landscapes. It will also cache core samples, a first step in the quest to return samples to Earth.
