An artist's imagined view from planet Kepler-10b (NASA/Kepler Mission/Dana Berry)
This new article in The Atlantic profiles NAI’s Virtual Planetary Laboratory team, based at the University of Washington, Seattle and led by PI Vikki Meadows. At a recent conference hosted there called “Revisiting the Habitable Zone,” a small interdisciplinary and international group of scientists discussed the question, “What makes a planet habitable?” aka, “What makes a planet’s surface suitable for water?”

Astrobiologists have solved a 55-year-old Moon mystery known as the Lunar Farside Highlands Problem.
When looking at the Moon from Earth, one of the first things you notice are the large, dark areas of basalt seas known as maria. These dark spots are what give the Moon it’s familiar 'face.’ For centuries this was the only view of the Moon that humankind knew because the nearside always faces ...June 13, 2014 / Written by: Aaron Gronstal

Please join us in welcoming a new crop of early career astrobiologists into two of the many community-based programs supported by NASA Astrobiology: the 2014 International Summer School in Astrobiology and the NASA Astrobiology Early Career Collaboration Award.
This year’s theme for the 2014 International Summer School in Astrobiology is “Habitable Environments in the Universe.” The school will provide an interdisciplinary examination of the nature and evaluation of habitability, an environment’s ability to support life. The Astrobiology Early Career Collaboration Award offers research-related travel support for undergraduate, graduate students, postdoctoral fellows and junior scientists.

Trinity Hamilton, an NAI NPP Fellow, takes samples from a thermal spring in Yellowstone National Park.
Humble beginnings in a one-room grade school in rural Montana led Trinity Hamilton to look to the stars. Now, as a NASA Postdoctoral Program Fellow with the NASA Astrobiology Institute, she brings her focus back to the ground to help expand our knowledge of the emergence of life on Earth.
“Understanding the role of biology in planetary evolution remains a daunting challenge to astrobiologists,” she said ...May 16, 2014 / Posted by: Daniella Scalice
This MARCI image from the Mars Reconnaissance Orbiter is a composite mosaic of the north polar cap. The images were taken at midnight, 6 a.m., noon, and 6 p.m. martian time, during the summer when the sun is always shining in the polar region. The image shows the mostly water-ice perennial cap (white area), sitting atop the north polar layered materials (light tan immediately adjacent to the ice), and the dark circumpolar dunes.

The NASA Astrobiology Program funds groundbreaking research around the globe, developing unique instruments to investigate some of Earth’s most remote and extreme environments. One such project is the Planetary Lake Lander, which is a prototype lander being tested in the high lakes of the Andes with an eye toward the exploration of Europa. In this series of videos, meet the researchers and learn about their work in unique and dramatic areas on Planet Earth.

Please join us in welcoming four new fellows to the NASA Astrobiology Minority Institution Research Support (MIRS) Program!
The goal of the NAI MIRS Program is to help train a new generation of researchers in astrobiology and to increase diversity within the astrobiology community. Over the past ten years, the program has provided opportunities for faculty members and students from minority-serving institutions to partner with astrobiology investigators.
One of the program’s main objectives is to engage more faculty from under-represented schools in astrobiology research and increase the number of students pursuing careers in astrobiology.
The four newest MIRS partnerships ...May 13, 2014 / Written by: Daniella Scalice

The stars in the night sky shine in myriad hues and brightnesses—piercing blues, clean whites, smoldering crimsons. Every star has a different mass, the basic characteristic that determines its size, lifespan, light output and temperature (which we discern as a particular color).
Yet when it comes to the existence of life, we know with certainty of only a single star—a toasty, yellow-whitish one, our Sun—that has permitted the rise of ...

Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA Astrobiology Institute-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.

The largest moon in our solar system, a companion to Jupiter named Ganymede, might have ice and oceans stacked up in several layers like a club sandwich, according to new NASA-funded research that models the moon’s makeup.
Previously, the moon was thought to harbor a thick ocean sandwiched between just two layers of ice, one on top and one ...May 2, 2014 / Posted by: Daniella Scalice

In 2011, Jennifer Glass joined a scientific cruise to study a methane seep off of Oregon’s coast. In these cold, dark depths, microbes buried in the sediment feast on methane that seeps through the seafloor.
A product of their metabolism, bicarbonate, reacts with calcium in seawater to form tall rocky deposits. The chemical energy these organisms extract from methane supports a vibrant underworld — an eclectic blanket of microbial mats, clam fields and tube worms.
“It’s such a beautiful landscape,” says Glass, an alumnus of NASA’s Astrobiology post-doctoral ...
A zircon from the Jack Hills in Western Australia was claimed to be 4.4 billion years old. The grain is probably less than 100 million years younger than the Earth–Moon system and is likely to be a remnant of the oldest continental crust. Image Credit: John Valley, Univ. Wisconsin
The age of the Earth’s crust is contentious, and geologic material available for analysis is few and far between. In a new study in Nature Geoscience, NAI-funded astrobiologists have mapped the distribution of radiogenic isotopes within an ancient zircon from the Jack Hills in Western Australia (a site ...April 28, 2014 / Posted by: Daniella Scalice
