How Low Can Geologists Go?
Scientists have begun the final leg of a five-year, NASA-funded mission to reach the bottom of Cenote Zacatón in Mexico, the world’s deepest known sinkhole.
No one has ever reached bottom and at least one diver has died in the attempt. Scientists want to learn more about Cenote Zacatón’s physical dimensions, the geothermal vents that feed it and the forms of life that exist in its murky depths.
Previous expeditions tested the robotic probe that...

Getting to the Core of Exoplanets: From Gas to Ice Giants
The measured masses and orbits of the 200 secure exoplanets within 200 pc reveal the processes of formation and subsequent dynamics. Several planets reveal information on their cores and interiors. Multiple-planet systems, especially those in resonances, inform us about migration, scattering, and capture. Planets from 5-14 Earth masses are now detectable, and several have been found. The Kepler Mission and a new 2.4-m “Automated Planet Finder” telescope at Lick Observatory portend the detection of...

NASA Predicts Non-Green Plants on Other Planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.
Green, yellow or even red-dominant plants may live on extra-solar planets, according to scientists whose two scientific papers appear in the March issue of the journal, Astrobiology. The scientists studied light absorbed and reflected by organisms on Earth, and determined that if astronomers were to look at the light given off by planets circling...

Discovering Earth-like Exoplanets
In this week’s Science, astrobiologists from NAI’s University of Hawai’i Team review the prospects for discovering smaller planets more like Earth, some of which may even have conditions suitable for life. Improved techniques and the ability to monitor fainter stars now enable astronomers to discover smaller planets, particularly planets orbiting much closer to their host star than the Earth is to the Sun. This review article is based on an NAI-supported session at the May, 2007 meeting of...

Coping with Contamination
Carol Stoker is the principal investigator for the Mars Analog Research and Technology Experiment (MARTE). MARTE has just begun its second field season drilling into the subsurface near the headwaters of the Río Tinto in Spain, searching for novel forms of microbial life. In a four-part interview with Astrobiology Magazine Managing Editor Henry Bortman, conducted just before Stoker left for Spain, she explained what MARTE hopes to accomplish. In this third part, Stoker described how...

Looking for Life in All the Right Places
This new video from JPL shows how NASA astrobiologists are gathering exciting clues that will help them pick the best spots to search for possible signs of life beyond Earth.
