• A Sliver of a Chance for Life on Mars
    The Phoenix Mars Lander witnessed water vapor adsorbing into the martian soil each night. Researchers suspect the films of water that resulted are probably too thin for life now, but they may have been thick enough millions of years ago.

  • Ice Age Aliens
    The light reflected off of vegetation could be a signal of life on an alien planet. Researchers have now shown that this plant life signal can be seen even if a world is in the midst of an ice age.

  • Early Attempts to Contact Aliens
    The idea that we Earthlings may not be alone is not new, nor is the idea of trying to signal our cosmic neighbors. The first era of interplanetary communication began in the 19th century.

  • Unmasking Europa
    We may not be able to judge a book by its cover, but hopefully we can judge a moon by its surface. A scientist who worked on the Galileo mission has written a new book about the scratched and splotchy surface of Europa.

  • Constant Comet Threat
    Comet impacts have likely transformed life on Earth, but it is still a mystery how these icy bodies are put on a collision course with our planet. New research says that nearby stars and the galaxy as a whole are to blame.

  • A Divining Rod for Mars
    Mars may have water underground but exactly where it is located is not known. An instrument on the Mars Science Laboratory will use neutrons to help spy for the water.

  • Life’s Boiling Point
    Some proteins can work above the boiling point of water, but these vital biomolecules may have a harder time evolving at high temperature. A new project is searching for the maximum temperature for protein-based life.

  • Cutting Life Short
    Imagine a solar system where a life-bearing planet is slowly pulled in closer to its star. If life could survive the ensuing climate change, it would provide a clear example of the Gaia hypothesis in action.

  • Measuring the Weight of Ancient Air
    In the first study of its kind, researchers will measure the air pressure from nearly three billion years ago by using gas bubbles in lava and tiny craters made by raindrops. The results could indicate what sort of life may have existed on the

  • Mini-Sub for Small Spaces
    New from the Nordic issue of Astrobiology Magazine, European Edition is a story about a tiny submarine. Swedish researchers are developing a remote-controlled submersible that can fit through drilled holes in thick ice caps.

  • Unlocking Martian Rocks
    A new study offers a simplified technique for detecting biological molecules in martian rock. The equipment is too large to be put on a rover, but it could be used to analyze samples brought back from Mars.

  • Ocean on Enceladus May Be Short-Lived
    Three years ago, surprising evidence came out for an ocean underneath the surface of Saturn's moon Enceladus. But a new report indicates just how hard it may be to keep water from freezing on this tiny moon.

  • Biological Stowaways on Mars
    Astrobiologists hope to find evidence for life on Mars. Sending spacecraft from Earth to study the planet could introduce biological contamination, however, and lead to a false detection of alien life. New research adds to these concerns with evidence that ATP -- an energy-storage
