Laboratory of Extraterrestrial Ocean Systems (LEOS)

From Deep?Sea through Deep?Time to Deep?Space



About us:

Extraterrestrial oceans refer to bodies of liquid water located beyond Earth, often found beneath the icy surfaces of moons like Europa, Enceladus, and Titan. These oceans are significant in the context of scientific research and exploration, particularly as they align with China's strategic goals in deep-sea and deep-space exploration. This interdisciplinary field merges scientific inquiry with engineering advancements, focusing on the potential for life beyond Earth. In December 2017, the Extraterrestrial Ocean Systems Research Laboratory was established to study these oceans and their host moons. The laboratory's research, led by the LEOS group, addresses critical questions regarding the origin and limits of life in the universe.?



Key Focus Include:

1. Circulation of substance and energy:?Investigating how these processes shape habitable environments in extraterrestrial oceans.

2. Potential Life Forms?and biosignatures:?Exploring the types of life that could exist in these oceans and identifying biosignatures that may indicate their presence.

3. Exploration Strategies: Developing technologies and methodologies to effectively explore extraterrestrial oceans and icy moons.

This research is crucial for understanding not only the potential for life beyond Earth, but also the broader implications for planetary habitability, prebiotic and abiotic carbon cycling, and the evolution of life in diverse environments.


Research Objectives:

The Extraterrestrial Ocean Systems Research Laboratory employs a multifaceted approach to enhance our understanding of extraterrestrial oceans on icy moons. The laboratory focuses on investigating fundamental issues, such as the mechanisms of formation and evolution of solar system water bodies, as well as the dynamic processes of matter and energy exchange between these ocean systems and their external environments. Key strategies utilized by the laboratory include leveraging diverse research methods like laboratory and numerical simulations to replicate extraterrestrial ocean conditions and analyzing specimens and data from Earth's extreme deep-sea environments as analogs. The laboratory also aims to establish an integrated "Extraterrestrial Ocean Extreme Environment Simulation System" for comprehensive studies of these enigmatic water bodies.

Furthermore, our research involves studying the interactions between seawater and the rock sphere in Earth's deep-sea and polar regions, as well as examining how cold-loving organisms adapt to such extreme conditions. This comparative analysis provides valuable insights into the potential habitability of extraterrestrial oceans. In addition, the laboratory conducts preliminary work on deploying and testing extraterrestrial ocean exploration equipment, laying the groundwork for future advancements in technologies necessary for exploring these distant worlds. By integrating these strategies, LEOS seeks to advance knowledge about the formation, evolution, and potential habitability of extraterrestrial oceans beyond Earth.


Research Interests:

Preservation and detection of biosignatures from deep-sea, deep-space and deep-time; Formation and evolution of extraterrestrial oceans; Potential physical, chemical, and biological processes in extraterrestrial oceans; Prebiotic and abiotic carbon cycling compared with biosignatures; In-situ and real-time analyses in deep-sea and deep-space environments; Exploration for extraterrestrial life and habitable environments for humans.?

Prof. Dominic Papineau
Senior Research Scientist in biogeochemistry and exobiology?


Educational Background:

Prof. Dominic Papineau graduated inn 2001 with a B.Sc. degree in physics (major) and biochemistry (minor) from McGill University, in Montréal, Québec, Canada. He then obtained his Ph.D. degree in 2006 in geosciences from the University of Colorado at Boulder, in the United States of America, along with a graduate certificate in astrobiology. Between 2006 and 2010, he conducted postdoctoral research at the Geophysical Laboratory of the Carnegie Institution of Washington (now called the “Earth and Planets Laboratory” at the Carnegie Institution for Science), in Washington D.C., in the United States of America.

?

Research?Experience:

After a brief time as an Assistant Professor at Boston College between 2010 and 2012, Prof. Papineau was a Professor at the University College London between 2013 and 2024, where he built a laboratory of geological spectroscopy. He now holds a honorary professor position in the Department of Earth Sciences at UCL. In 2024, Prof. Papineau joined the Institute of Deep-sea Science and Engineering at the Chinese Academy of Sciences. His research interests are aimed at understanding the origin and evolution of life on Earth, and to pave the way to search for extraterrestrial life on other planetary bodies. His research approach revolves around ‘correlative microscopy’, which involves visually correlated micro-analytical techniques to characterize geochemical compositions of minerals, rocks, and fossils. These techniques include polarizing microscopy, micro-Raman spectroscopy, infrared micro-spectroscopy (FTIR and PiFM), Scanning Electron Microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Focused Ion Beam (FIB), Transmission Electron Microscopy (TEM), Energy Dispersive Spectroscopy (EDS), Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS), synchrotron-based Scanning Transmission X-ray Micro-spectroscopy (STXM), and Atom Probe Tomography (APT). The integration of this arsenal of techniques to analyze microscopic mineral assemblages associated with organic matter in Precambrian, deep-sea, and extraterrestrial rocks provides complementary analyses of elemental, isotopic, and molecular compositions. Prof. Papineau has published more than 80 peer-reviewed papers, including in Nature, Nature Geoscience, Nature Communications, Science Advances, Geology, Geochimica et Cosmochimica Acta, Earth and Planetary Science Letters, Precambrian Research, Geobiology, and Chemical Geology. Between 2012 and 2013, he was a NASA Early Career Fellow and was affiliated with the NASA Astrobiology Institute between 1999 and 2012. As of 2024, he has trained numerous research students, including 3 postdocs, 11 Ph.D., 31 M.Sc., and 12 B.Sc.
