Marine Subsurface is a Distinct Microbial Habitat
Researchers from NAI’s Penn State, MBL, and UCLA Teams have completed a study of the subseafloor marine biosphere, which may be one of the largest reservoirs of microbial biomass on Earth, and has recently been the subject of debate in terms of the composition of its microbial inhabitants. Their metagenomic analysis indicates that the subsurface environment is the most unique studied to date, distinct in its microbial make-up from the surface waters. The slowly-metabolizing populations may...

New Extrasolar Planetary System May Be Much Like Our Own
Researchers from the NAI’s University of Arizona Team have published a new study in the current issue of Astrophysical Journal Letters of the potential habitability of the extrasolar planetary system OGLE-2006-BLG-109L. The first multiple-planet system ever to be discovered by gravitational microlensing, it has two large planets similar to Jupiter and Saturn. It’s possible that the system harbors other planets, including Earth-like planets, that are beyond the sensitivity...

Moon Samples Found to Contain Water
Using new techniques, scientists from NAI’s Carnegie Institution of Washington Team have discovered for the first time that tiny beads of volcanic glasses collected from two Apollo missions to the Moon contain water. The researchers found that, contrary to previous thought, water was not entirely vaporized in the violent events that formed the Moon. The new study suggests that the water came from the Moon’s interior and was delivered to the surface...

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...
