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.

Smart Sparrow and NAI-funded researchers and educators at Arizona State University announce the launch of a new type of online course! HabWorlds Beyond is a platform that lets educators create rich, interactive and adaptive learning experiences. It teaches students about space exploration, climate science, and the search for life on other planets. Centered on one of the most profound questions in science – does life exist elsewhere in the Universe? HabWorlds Beyond uses game-like simulations to expose students to the thought processes and practice of science in a fun and engaging way.

This artist's concept of Jupiter's moon Ganymede, the largest moon in the solar system, illustrates the "club sandwich" model of its interior oceans. Scientists suspect Ganymede has a massive ocean under an icy crust. Image Credit: NASA/JPL-Caltech
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
Due to unexpected personal conflicts, Dr. Michael Meyer has declined the position of NAI’s Interim Director. Dr. Meyer explains, “Unfortunately, the requirements levied to resolve a conflict-of-interest were unacceptable. I am disappointed that I am unable to accept the Interim Director position with NAI – I very much looked forward to re-engaging with the great work being done at the NAI.” Dr. Steve Zornetzer, Associate Director for Research and Technology at Ames Research Center, indicated that the Center will consider appointing another Interim Director for NAI while re-establishing the search for a distinguished scientific leader for the permanent Director’s ...April 24, 2014 / Posted by: Julie Fletcher
Tilted orbits might make some planets wobble like a top that's almost done spinning, an effect that could maintain liquid water on the surface. Image Credit: NASA's Goddard Space Flight Center
Pivoting planets that lean one way and then change orientation within a short geological time period might be surprisingly habitable, according to new modeling by NASA and university scientists affiliated with the NASA Astrobiology Institute.
The climate effects generated on these wobbling worlds could prevent them from turning into glacier-covered ice lockers, even if those planets are somewhat far from their stars. And with some water remaining ...

Scientists supported by the Astrobiology Technology for Exploring Planets (ASTEP) and Astrobiology Instrument Development Programs (ASTID) have outlined the proposed 'Icebreaker’ mission to Mars in a recent paper in the Journal of Field Robotics.
Icebreaker would send a robotic lander to the same region of Mars visited by the Phoenix mission in 2007. After landing at Mars’ polar latitudes, Icebreaker would use its tools to penetrate the surface and excavate samples. The goal is to see what is hiding beneath the ice caps, and whether or not Icebreaker ...April 22, 2014 / Written by: Aaron Gronstal

Using NASA’s Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.
While planets have previously been found in the habitable zone, they are ...April 17, 2014 / Posted by: Daniella Scalice
The research team, from right to left, co-authors Eoghan Reeves, Jill McDermott, and Jeff Seewald and their WHOI colleagues Frieder Klein and Sean Sylva used isobaric gas-tight samplers (IGTs) to collect and analyze samples of hydrothermal vent fluids (Jason pilot Scott Hansen peeks out from the background) on a cruise to the Cayman Trough in 2012. Seewald developed the samplers to collect fluids, some exceeding 700°F, and return them to the surface under pressure to preserve their physical and chemical composition.

Michael Russell and Laurie Barge of NASA's Jet Propulsion Laboratory, Pasadena, Calif., are pictured in their Icy Worlds laboratory, where they mimic the conditions of Earth billions of years ago, attempting to answer the question of how life first arose.
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet’s living kingdoms. How did it all begin?

The disturbance visible at the outer edge of Saturn's A ring in this image from NASA's Cassini spacecraft could be caused by an object replaying the birth process of icy moons.
NASA’s Cassini spacecraft has documented the formation of a small icy object within the rings of Saturn that may be a new moon, and may also provide clues to the formation of the planet’s known moons.
Images taken with Cassini’s narrow angle camera on April 15, 2013 show disturbances at the very edge of Saturn’s A ring — the outermost of the planet’s ...April 14, 2014 / Posted by: Daniella Scalice
