NASA’s Kepler Mission Discovers Bigger, Older Cousin to EarthThis artist's concept compares Earth (left) to the new planet, called Kepler-452b, which is about 60 percent larger in diameter. Credits: NASA/JPL-Caltech/T. Pyle
NASA’s Kepler mission has confirmed the first near-Earth-size planet in the “habitable zone” around a sun-like star. This discovery and the introduction of 11 other new small habitable zone candidate planets mark another milestone in the journey to finding another “Earth.”
The newly discovered Kepler-452b is the smallest planet to date discovered orbiting in the habitable zone — the area around a star where liquid water could pool on the surface of an orbiting planet — of a G2-type star, like our sun. The confirmation of Kepler-452b brings the total number of confirmed planets to 1,030.

How Much Contamination is Okay on the Mars 2020 Rover?One sample return prototype would hold a cache of up to 31 samples that could be returned to Earth at a later date. Credit: NASA/JPL-Caltech
When the Mars 2020 rover arrives on the Red Planet, one of its primary mission goals will be to select and preserve samples that would eventually make it back to Earth for scientific study. Rather than seeking to eliminate contamination of these samples completely, essentially an impossible task, a panel of scientists and engineers met to assess the levels at which significant science could still occur.
“The whole point of going [to Mars] and returning samples is that we don’t know what’s there and we want to find out,” Alex Sessions, of the California Institute of Technology, told Astrobiology Magazine. “This makes knowing how much contamination is acceptable a rather ambiguous task.”
Sessions served alongside Roger Summons, of the Massachusetts Institute of Technology, as co-chair of the Organic Contamination Panel for Mars 2020, which met to discuss the issue of Earth-side contamination.
“We want it [contamination] to be low enough to give us a good shot at seeing what we think could be there, without being overly conservative, which could cause the mission to be so expensive the whole thing gets scrapped.”

The results of the study were published on the NASA Astrobiology Program website and in the journal Astrobiology. The Organic Contamination Panel was a temporary group chartered and funded by NASA’s Mars Exploration Program.
‘Snowball Earth’ Might Have Been SlushyImage credit: Massachusetts Institute of Technology
Imagine a world without liquid water — just solid ice in all directions. It would certainly not be a place that most life forms would like to live.
And yet our planet has gone through several frozen periods, in which a runaway climate effect led to global, or near global, ice cover. The last of these so-called “Snowball Earth” glaciations ended around 635 million years ago when complex life was just starting to develop. It’s still uncertain if ice blanketed the entire planet, or if some mechanism was able to halt the runaway.
With support from the Exobiology & Evolutionary Biology element of the NASA Astrobiology Program, a team of scientists has been taking global climate models — the ones most people use to predict where our planet is heading in the future — and modifying them to study where our planet has been in the past.
‘Bathtub Rings’ Suggest Titan’s Dynamic SeasCassini VIMS/RADAR hybrid image of filled and dry lakes south of Titan’s methane sea Ligeia Mare. Blue arrows indicate current lakes, while the white arrows point to evaporates on dry lakes. Credit: NASA / JPL / UA
Saturn’s moon, Titan, is the only object in the Solar System other than Earth known to have liquid on its surface. While most of the hydrocarbon lakes are found around the poles, the dry regions near the equator contain signs of evaporated material left behind like rings on a bathtub that, when combined with geological features, suggest that the location of the liquids on the moon has shifted over time.
Researchers supported by the NASA Astrobiology Institute (NAI) element of the Astrobiology Program have been looking at evaporites on Titan and what they can tell us about the history of liquid at the moon’s surface. Their work was published in the journal Icarus.
Pathways for Life’s Origin on the Ocean FloorA view of a hydrothermal vent at the Main Endeavour Field on the Juan de Fuca Ridge, snapped from the submersible Alvin. Credit: Woods Hole Oceanographic Institution
Astrobiologists have uncovered two reaction pathways at hydrothermal vents that could produce organic compounds relevant to the origin of life on Earth and other worlds. For the origin of life as we know it, organic compounds need to be formed from inorganic precursors. Theories suggest that natural reactions could form these compounds at hydrothermal vents on the ocean floor, where warm fluids rich in hydrogen are released.
In a study supported by the Exobiology & Evolutionary Biology element of the NASA Astrobiology Program, researchers have revealed two reaction pathways that transform carbon-containing molecules into forms that life can use. Contrary to previous theories, the two pathways do not need fluids circulating in the environment. Instead, molecules are formed in small spaces in rocks where the fluids are trapped. The paper, “Pathways for abiotic organic synthesis at submarine hydrothermal fields,” was published in the Proceedings of the National Academy of Sciences (PNAS).

While the Rosetta spacecraft orbits the 67P/Churyumov-Gerasimenko comet, the Philae lander, deployed from Rosetta on November 2014, has gathered data on the surface of the comet that indicate the potential existence of prebiotic organics during the early solar system.
The lander’s Cometary Sampling and Composition (COSAC) evolved-gas analyzer utilized a “sniffing” mode, allowing molecules in the atmosphere to passively enter the instrument and then ionizing and accelerating the molecules for mass spectral interpretation. Through this method, COSAC detected a suite of 16 organic compounds, including several nitrogen-bearing species and four compounds not previously reported on other comets: methyl isocyanate, acetone, propionaldehyde, and acetamide. The detected molecules are building blocks for simple sugars, amino acids, and DNA and RNA, as pointed out by co-author Pascale Ehrenfreund from the NAI Wisconsin Astrobiology Research Consortium.

A recently designed probe takes the analysis of Hadean-age zircon to the level of a single atom, broadening scientists’ understanding of the ancient mineral and its relation to the history of Earth.
In his Presidential Address to the Mineralogical Society of America last July, John Valley of the NAI team at the University of Wisconsin-Madison wrote about development of new instruments and a combination of atom-probe tomography (APT) and secondary ion mass spectrometry (SIMS). APT magnifies sections of zircon up to a million times smaller than SIMS and identifies the mass and three-dimensional position of individual atoms. Paired with SIMS observations, the atom probe provides a fuller picture of the atomic distribution, age, effects from radiation, and crystallization and thermal history of the zircon. These findings support theories about crust formation and the existence of habitable oceans on a relatively cool Earth earlier than 4.3 billion years ago.
The full paper, “Nano- and micro-geochronology in Hadean and Archean zircons by atom-probe tomography and SIMS: New tools for old minerals,” is available through the Mineralogical Society of America.
Mini-Neptunes Might Host Life Under Right ConditionsArtist’s impression of Roche lobe overflow in a planet. Credit: NASA/GSFC/Frank Reddy
Researchers with the NASA Astrobiology Institute’s Virtual Planetary Laboratory Team at the University of Washington have described how mini-Neptune planets could become viable for life around M-Dwarf stars.
M-Dwarfs are cooler than the Sun, meaning any habitable planets around them would have to be much closer to their host star. However, planets in such systems face many hazardous conditions, particularly in the early stages of formation, that could make it difficult for life to take hold.
The study, published in the journal Astrobiology, indicates that mini-Neptunes could potentially migrate into the habitable zones of M-Dwarf stars and become habitable for life as we know it.

Anyone who’s ever noticed a water puddle drying in the sun has seen an environment that may have driven the type of chemical reactions that scientists believe were critical to the formation of life on the early Earth.
Research at the Georgia Institute of Technology, reported in the journal Angewandte Chemie International Edition, demonstrates that important molecules of contemporary life, known as polypeptides, can be formed simply by mixing amino and hydroxy acids—which are believed to have existed together on the early Earth—then subjecting them to cycles of wet and dry conditions.
This simple process, which could have taken place in a puddle drying out in the sun and then reforming with the next rain, works because chemical bonds formed by one compound make bonds easier to form with the other.
The research—supported by the National Science Foundation (NSF) Centers for Chemical Innovation Program and the NASA Astrobiology Program under the NSF/NASA Center for Chemical Evolution—supports the theory that life could have begun on dry land, perhaps even in the desert, where cycles of nighttime cooling and dew formation are followed by daytime heating and evaporation.

New Method Finds Best Candidates for Telescope TimeIf starlight passing through a planetary atmosphere is blocked by clouds or haze, the resulting spectrum is flat and featureless, and no molecules or potential biomarkers are visible.

If life exists on planets beyond our Solar System, its presence could be obscured by the haze and clouds in the planet’s atmosphere.
Even next generation telescopes — such as the James Webb Space Telescope (JWST) as well as ground-based telescopes like the European Extremely Large Telescope (E-ELT) — will have a hard time penetrating such hazy worlds in search of biomarkers. Astronomers Amit Misra and Victoria Meadows of the University of Washington have developed a new technique to check if a planet has clear skies, which will make it easier for astrobiologists to target the most promising exoplanet candidates for life.
Their research has been published in the Astrophysical Journal Letters and was funded by the NASA Astrobiology Institute element of the Astrobiology Program at NASA.
Antarctic Offers Insights Into Life on MarsOperation IceBridge project scientist Michael Studinger took this photo of Taylor Valley, one of the Dry Valleys of Antarctica where snow and ice are rare. Credit: NASA
The cold permafrost of Antarctica houses bacteria that thrive at temperatures below freezing, where water is icy and nutrients are few and far between. Oligotrophs, slow-growing organisms that prefer environments where nutrients are scarce, could provide clues as to how life could exist in the permafrost of Mars. In this vein, scientists have been studying the lethargic bacteria from the Dry Valleys of Antarctica, a row of snow-free valleys that represents one of Earth’s most extreme desert environments.
The research was published in the journal FEMS Microbiology Ecology and was funded by the NASA Astrobiology Science and Technology for Exploring Planets program.
NASA Researchers Find “Frozen” Recipe for Extraterrestrial VitaminA picture of the aluminum plate with a chemical deposit on it. Credits: Karen Smith/NASA Goddard
Vitamin B3 could have been made on icy dust grains in space, and later delivered to Earth by meteorites and comets, according to new laboratory experiments by a team of NASA-funded researchers. Vitamin B3, also known as niacin or nicotinic acid, is used to build NAD (nicotinamide adenine dinucleotide), which is essential to metabolism and probably ancient in origin. The result supports a theory that the origin of life may have been assisted by a supply of biologically important molecules produced in space and brought to Earth by comet and meteor impacts.
This work was supported by the NASA Astrobiology Institute (NAI) via the Goddard Center for Astrobiology (GCA), and the NASA Cosmochemistry Program. The study was published in Chemical Communications.
Barnacles Explain Life at the ExtremeStalked barnacles from the vent fields at the Kawio Barat volcano, Western Pacific. Credit: NOAA Okeanos Explorer Program, INDEX-SATAL 2010
Barnacles — a type of marine crustacean — are highly adaptable animals. Unlike many other groups that prefer quieter waters, they like areas with a lot of activity, are hardy against dry spells that sometimes occur in tidal zones, and can even persist in waters that are becoming more acidic due to human pollution.
Our solar system is full of icy moons – for example, Jupiter’s Europa or Saturn’s Enceladus — that likely have global oceans under their crusts. Finding out how species on Earth exist in harsh environments could help scientists understand ways life might colonize the Outer Solar System.
“If the ecosystems there function in a similar way to the ones we have on Earth, we would expect similar processes,” said Santiago Herrera, a postdoctoral fellow in biology at the University of Toronto in Canada.
At the time he did his research on barnacles, he was obtaining his joint doctorate in biological oceanography at the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution. The outcome of Herrera’s barnacle research was published in January 2015 in the journal Molecular Ecology, titled “Evolutionary and biogeographical patterns of barnacles from deep-sea hydrothermal vents.”
Herrera’s research centered on how barnacles distribute themselves in time and space. Part of his interest was driven by the effects humans may have on these marine creatures through pollution, deep-sea mining and disruption of climate patterns. But Herrera and his team was also interested in how barnacles distribute themselves in deep-sea vents, such as those found in the Pacific and Indian oceans.
Vents are considered a proxy of the extreme conditions that might comprise an extraterrestrial habitat. Because vents often contain energy and chemicals spewing from beneath the surface, they can act as a catalyst for organisms seeking life.
To gain more information about how the barnacles are distributed, Herrera’s team examined roughly 20 years of samples from different expeditions. All told, they had more than 100 specimens collected from several dozen vent fields worldwide.
The work was partially funded by the Astrobiology Science and Technology for Exploring Planets element of the NASA Astrobiology Program.
Solar Events Unlikely Triggers for Birth Defects on EarthAir showers ensuing from very-high-energy cosmic rays can enter Earth’s atmosphere from multiple directions. Credit: Simon Swordy/NASA
Previously, studies have found that airplane crews at high altitude are exposed to potentially harmful levels of radiation from cosmic rays. But could these cosmic rays pose hazards even at sea level?
A new NASA-funded investigation has found radiation from solar events is too weak to cause worry at ground level. Results have just been published in the Journal of Geophysical Research and are hailed as one of three “Editor’s Choice” publications for the first quarter of 2015 by Space Weather.
The study was supported by the Exobiology and Evolutionary Biology element of the NASA Astrobiology Program.
A Biological Source of Iron in BIFsRocks at Soudan Underground Mine State Park, Minnesota, show banding caused by layers of different minerals in a sample 2.7 billion years old. Credit: University of Wisconsin-Madison, http://news.wisc.edu/23863
A new study identifies sources of iron found in Banded Iron Formations (or BIFs) that were formed 2.5 billion years ago. The BIFs are sedimentary deposits formed at the bottom of Precambrian oceans on Earth, and contain distinctive layers of material. BIFs are reddish in color due to the iron they contain, and these deposits are a major source of iron used by humankind today.
Previously, much of the iron in BIFs was thought to come from mineral-rich water released by hydrothermal vents. The new study indicates two sources of iron in BIFs from Western Australia. The first source is hydrothermal systems on the ocean floor. The second source is iron metabolized by microorganisms living along the continental shelves. The researchers suggest that a large amount of continental iron was released into the ancient ocean through microbial iron reduction. The study shows that iron in BIFs resulted from the interplay between biological and abiologic processes.
The paper, “Biologically recycled continental iron is a major component in banded iron formations,” was published in the journal PNAS. The study was supported by the NASA Astrobiology Institute.
Icy Material on Pluto and CharonAs New Horizons closes in on Pluto and Charon, it may be able to detect signs that one or both objects boast icy plumes, either now or in their past. Credits: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute
A new study of objects in the outer reaches of the solar system suggests that bodies like Pluto and Charon have the potential to support eruptions of icy material. The research indicates that if cryo-volcanism has occurred on Pluto, Charon’s surface could retain evidence of such events.
The research was published online in the journal Icarus, and was supported by the NASA Astrobiology Institute team at Arizona State University.

Postdoctoral Fellowships in Interdisciplinary Research Relating to Origins of Life
2nd Application Deadline: October 1, 2015
The ELSI Origins Network (EON) announces the availability of post-doctoral research fellowships for research related to the Origins of Life. Ten two-year positions will be funded, to take place within the period 2016-2018.
Successful candidates will split their time between the Earth-Life Science Institute (ELSI) in Tokyo and another institution of the candidate’s choice, anywhere in the world. The fellowship will pay a salary for two years, which covers the time spent at both locations, as well as a generous research budget. The positions will start on or before 1st April 2016.
EON is an interdisciplinary international network which seeks to foster dialogue and collaboration within the Origins of Life community to articulate and answer fundamental questions about the nature and the reasons for the existence of life on Earth, and possibly elsewhere in the Universe. Its goal is to bring together leading-edge research in all areas of the physical, mathematical, computational, and life sciences that bears on the emergence of life. ELSI is chartered as a Japanese World Premier International Research Center, to study the origin of Earth-like planets and the origin of life as inter-related phenomena. ELSI is located at the Ookayama campus of Tokyo Institute of Technology.
EON-supported research addresses three overarching questions:
1. How did life emerge on Earth?
2. How common is life in the universe?
3. What fundamental principles explain the emergence of life?
Due to the split-time nature of these fellowships, the application process requires the applicant to choose a supervisor and host institution outside ELSI who will support the proposal. EON is designed to promote collaboration across disciplinary boundaries, and host institutions in all fields are welcome.
The goal of the fellowships is cross-fertilization between specialists in Origin of Life research around the world, with a central collaborative hub at ELSI. EON aims to build a research community in which postdoctoral fellows benefit from facilities not only at ELSI but also among the centers throughout the network.
The second deadline on 1st October will fill remaining places. Please check our web site http://eon.elsi.jp/ for more details, including the application procedure.
