Extraterrestrial Nucleobases in the Murchison Meteorite
A recent study in Earth and Planetary Science Letters from NAI’s Teams at NASA Goddard Space Flight Center, Carnegie Institution of Washington, and University of Wisconsin, shows that nucleic acids of extraterrestrial origin are present in the Murchison meteorite. Carbon-rich meteorites such as the Murchison are thought to be responsible for delivering biologically-relevant organic material to the young Earth. These results demonstrate that the nucleic acids discovered in the...

The Color of Alien Plants
The April 2008 issue of Scientific American features an article by Nancy Kiang of NAI’s Virtual Planetary Laboratory Team based on her studies predicting the colors of plants on other worlds. The studies, published in Astrobiology in February 2007, consider that as photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for...

Final Assembly of Earth-Like Planets
NAI Postdoctoral Fellow Sean Raymond leads a team of authors from NAI’s University of Colorado, Boulder, and University of Arizona Teams, and Virtual Planetary Laboratory and University of Washington Alumni Teams in a new publication in Astrobiology. They present analysis of water delivery and planetary habitability in 5 high-resolution simulations forming 15 terrestrial planets. Their results outline a new model for water delivery to terrestrial planets in dynamically calm systems, which may be very common in the Galaxy.
