Our Earth is about 70% covered in ocean, and the seafloor is a blanket of unconsolidated sediment made up of a wide range of organic matter, minerals, and chemistries. The habitable portions of ocean sediment provide living space for an estimated 3×1029 microbial cells.
Scientists with the NASA Astrobiology Institute (NAI) Life Underground team based at the University of Southern California have used data on global sediment thickness, ocean depth, heat flow, and bottom water temperatures to developed a model to calculate the three-dimensional distribution of temperature in sediments.
The research, “Temperature and volume of global marine sediments ...

In the summer of 2016, Penny Boston, Director of the NASA Astrobiology Institute (NAI), presented the seminar, Subsurface Astrobiology: Cave Habitat on Earth, Mars, and Beyond at NASA Ames Research Center in Mountain View, CA. She talked about her past work exploring and studying caves around the world, where the extreme subsurface conditions and the discovered microbial life forms held possible clues for future Mars exploration and the search for life in our solar system.
Boston’s talk is part of the annual NASA Ames Summer Series, which invites subject leaders from around the world to present science and technology discoveries ...

Compelling terrestrial evidence records active and ancient serpentinization, the process that occurs when ultramafic rocks come into contact with water. This process may have been active on the surface and subsurface of Mars, beneath the surface of icy satellites such as Enceladus and Europa, and beyond. On Earth, these geochemical interactions support distinct microbial ecosystems.
The purpose of this workshop is to highlight recent advances in understanding how Serpentinizing Systems function chemically and biologically within our Solar System.
Each day of this 3-day workshop will begin with an overview by a Theme Lead, followed by several invited talks (list below ...

For three billion years or more, the evolution of the first animal life on Earth was ready to happen, practically waiting in the wings. But the breathable oxygen it likely required wasn’t there, and a lack of simple nutrients may have been to blame.
Then came a fierce planetary metamorphosis. Roughly 800 million years ago, in the late Proterozoic Eon, phosphorus, a chemical element essential to all life, began to accumulate in shallow ocean zones near coastlines widely considered to be the birthplace of animals and other complex organisms, according to a new study by geoscientists from the Georgia ...

The 5th ELSI International Symposium, Expanding Views on the Emergence of the Biosphere, takes place January 11-13, 2017 in Tokyo, Japan. Talks will be webcast via SAGANet.org.
The Earth-Life Science Institute (ELSI) presents its 5th International Symposium: Expanding Views on the Emergence of the Biosphere.
January 11th-13th, 9AM – 5PM (GMT+9)
Earth-Life Science Institute, Tokyo Institute of Technology, Japan
Conference website: www.elsi5sympo.org
The emergence of a biosphere on Earth, and possibly elsewhere in the universe, remains one of the great unsolved scientific questions. Research into the origin and subsequent evolution of life takes place across an array of scientific disciplines, including but not limited to planetary sciences, astronomy, theoretical physics, chemistry and biology. The goal of this Symposium is to provide a forum for ...

Before it became visible as the Pale Blue Dot, early Earth may have been aglow in orange, and this might have helped to make it habitable.
Scientists at the Virtual Planetary Laboratory, the NASA Astrobiology Institute (NAI) team based at the University of Washington, have developed a simulation of Earth during the Archaen era (3.8-2.5 billion years ago), with the atmosphere supporting an organic-rich and orange-colored haze that—shifting from previous haze studies— provided UV and temperature shielding to support the existence of life.
The paper, “The Pale Orange Dot: The Spectrum and Habitability of Hazy Archaen Earth,” was ...

Scott Sandford, PI of the NAI Team at the NASA Ames Research Center, joined David Livingston to discuss astrobiology.
In August 2016, PI Scott Sandford of The Evolution of Prebiotic Chemical Complexity and the Organic Inventory of Protoplanetary Disks and Primordial Planets, the NASA Astrobiology Institute (NAI) team based at the NASA Ames Research Center, was a guest on the Space Show radio program hosted by David Livingston.
In the program, Sandford gave his explanation of the science of astrobiology and ways to think about the search for life in the Universe. Topics and questions also ranged from his research at the Ames labs, the OSIRIS-Rex mission, working with the NAI, and how aspiring astrobiologists can pursue a ...

In the effort to understand the history of Earth’s oxygenation, scientists have sought geochemical proxies, but studies don’t always fully consider how samples get preserved within the ancient environment and how that may affect results, especially when it comes to marine carbonates which can be altered during rock transitions and formations.
NASA Astrobiology Postdoctoral Program fellow Ashleigh Hood and the Alternative Earths team looked at uranium isotopes in samples from a reef complex in South Australia dating back over 635 millions ago. The research paper, “Integrated geochemical-petrographic insights from component-selective δ238U of Cryogenian marine carbonates” was featured on ...

The relationship between the cellular composition and size of a species of bacteria can determine how and how well it functions. Scientists with the Life Underground team at the University of Southern California have collected data on a diverse range of bacterial cells spanning five orders of magnitude to call out the cross-species connections between cellular form and function. The paper, “Evolutionary tradeoffs in cellular composition across diverse bacteria” is published in The ISME Journal.
The team compared cell volume against the amount of DNA, ribosomes, proteins, cell membrane, tRNA, and mRNA contained within, and focused on power-law relationships—how a ...

Geochemist Barbara Sherwood Lollar, professor of Earth Sciences at the University of Toronto and a past affiliate of the NASA Astrobiology Institute, has received the status of Companion of the Order of Canada, the highest level of honor for the Order. She is recognized for “revolutionary contributions to geochemistry, notably in the development of innovative mechanisms for groundwater remediation, and for her discovery of ancient fluids that hold implications for life on other planets.”
The ancient fluids are a reference to water trapped beneath the Earth’s surface released through mining fractures, which Sherwood Lollar and her team discovered ...
