With more than a thousand confirmed planets outside of our solar system, astronomers are attempting to identify the atmospheres of these distant bodies to determine if they could possibly host life.
Yet, viewing a body so far away remains a challenge. Astronomers are honing their technique in exoplanet observation with an object we know much more about in our own solar system — Saturn’s moon, Titan. The process should help ...
Despite being similar sizes, Earth (right half) and Venus (left half) have different surface conditions, a fact that has implications in the search for an Earth-like exoplanet. Credit: NASA/JPL-Caltech/Ames
In order to weed out Venus-like planets from those that would be more habitable, scientists proposed the establishment of a “Venus zone” around stars, a region where the atmosphere could be consumed by a runaway greenhouse effect that super-heats its planets. So far, the team of scientists has identified 43 potential Venus analogs, and think that even more exist.
One of the researchers, Stephen Kane of ...

By studying colonies of volvocine green algae, astrobiologists have uncovered new clues about how cells gained the ability to differentiate into functional types, a critical step in the evolution of multicellular organisms.
The paper, “Fitness trade-offs and developmental constraints in the evolution of soma: an experimental study in a volvocine alga,” was published in the journal Evolutionary Ecology Research.

Scientist supported in part by the NASA Astrobiology Institute have discovered that certain specimens of fossil Dickinsonia appear incomplete because they were lifted from the sea floor by ancient ocean currents, allowing sand to fill in the gap. The results suggest that Dickinsonia was mobile and not attached to the sea floor.
The study, “Dickinsonia liftoff: Evidence of current derived morphologies,” was published in the journal ...April 28, 2015 / Posted by: Aaron Gronstal
NASA is bringing together experts spanning a variety of scientific fields for an unprecedented initiative dedicated to the search for life on planets outside our solar system.
The Nexus for Exoplanet System Science, or “NExSS”, hopes to better understand the various components of an exoplanet, as well as how the planet stars and neighbor planets interact to support life.
“This interdisciplinary endeavor connects top research teams and provides a synthesized approach in the search for planets with the greatest potential for signs of life,” says Jim Green, NASA’s Director of Planetary Science. “The hunt for exoplanets is not only ...April 24, 2015 / Posted by: Aaron Gronstal

The American Geophysical Union (AGU) has recognized two early career astrobiologists.
Giulio Mariotti received the 2014 Luna B. Leopold Young Scientist Award for his work on the interactions of coastal hydrodynamics, morphodynamics, and ecological processes. Mariotti was a participant in the 2013 Australian Astrobiology Tour with the The Australian Centre for Astrobiology (ACA), one of the first international partners of the NASA Astrobiology Institute.

Researchers at NASA are currently hard at work on the proposed Mars 2020 rover, which will expand upon previous missions to help determine Mars’ potential habitability, both past and present. One task the rover might face is to collect and cache scientific samples that could one day be returned to Earth for further study.
Protecting such samples from contamination has been identified as an important and complex issue by the Mars Exploration Program Analysis Group (MEPAG), and was the subject of an independent investigation by the Mars 2020 Organic Contamination Panel (OCP).
In 2014, the OCP convened to evaluate and ...April 15, 2015 / Written by: Aaron Gronstal

A new study reveals that viruses lend a surprisingly helpful hand to microbes eking out a living near deep-sea hydrothermal vents. When they infect the vent’s resident bacteria and archaea, the viruses mix and match the single-celled creatures’ genes. As a result, the microbes can benefit from possessing a wide range of genes in a way that broadens their repertoire of responses to the quick-changing, harsh conditions of the vent environment.

A new study is helping astrobiologists understand how bacteria adapt to environmental conditions during infections. The researchers paired experimental evolution and modern sequencing techniques to study adaptations in biofilm bacteria when recovering from pathogen infection.
The study, “There and back again: consequences of biofilm specialization under selection for dispersal,” was published in the journal Frontiers in Genetics
This research was supported in part by the NASA Astrobiology Institute (NAI).
