Elizabeth Trembath-Reichert. a NASA Postdoctoral Porgram fellow at the Woods Hole Oceanographic Institution and a member of the NASA Astrobiology Institute team based at the University of Southern California, is lead author on a paper that measures the activity level and generation times of microbes living in coal and shale beds up to two kilometers below the seafloor. Despite low cell numbers and slow reproduction, the microbes actively consume carbon and nitrogen compounds from their environment.
The paper, “Methyl-compound use and slow growth characterize microbial life in 2-km-deep subseafloor coal and shale beds” is published in Proceedings of the National Academy of Sciences.

The early Earth was a hellish place, pummeled by meteors and a choking atmosphere, and yet somehow life got a grip there.

Wednesday, October 25, 2017, 6:30 PM ET What does it mean to be a habitable planet? How can we find life if it’s truly “alien” and different from life on Earth? And what techniques can we use to search for life on worlds orbiting distant stars? Drs. Arney and Domagal-Goldman, astrobiologists at NASA Goddard Space Flight Center, will discuss the science behind these questions and the future telescopes that may provide the answers. The lecture at the Carnegie Institution for Science will be streamed live. For details, visit the event page.

Screenshot from the Life Underground Game where students take the role of investigators of extreme subsurface environments looking for microbial life.
The NASA Astrobiology Institute has funded the production of an exciting, new educational game/software called Life Underground. In the game, students take on the role of a young scientist navigating and investigating a subsurface environment, searching for and characterizing microbial life.

Life on early Earth seems to have begun with a paradox: while life needs water as a solvent, the essential chemical backbones of early life-forming molecules fall apart in water. Our universal solvent, it turns out, can be extremely corrosive.
Some have pointed to this paradox as a sign that life, or the precursor of life, originated elsewhere and was delivered here via comets or meteorites. Others have looked for solvents that could have the necessary qualities of water without that bond-breaking corrosiveness.

Fall is officially upon us, but not too long ago early career astrobiologists were keeping busy throughout the summer season. AbGradCon 2017 and the Proposal Writing Retreat—organized by and for post-docs, graduate students, and select undergrads—met with great success. The 2017 International Summer School in Astrobiology gathered 22 scholars to the Universidad Internacional Menéndez Pelayo (UIMP) in Santander, Spain to learn about exoplanet habitability. And undergraduates collaborating with scientists at Goddard Space Flight Center presented a GSFC Summer Research Associate 2017 Seminar on their innovative research.

You can now watch the Library of Congress symposium “Life As It Could Be: Astrobiology, Synthetic Biology, and the Future of Life” hosted by Luis Campos, the 2016-2017 Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology. The event took place Thursday, September 28, 9AM-6PM ET.
What is life? How might life have emerged on Earth or on other worlds? And how might we engineer the future of life—what might we make life to be? Astrobiologists and synthetic biologists grapple with these questions every day. To further explore the intersections between these sciences and the humanities, the ...
