Ocean Worlds Exploration and the Search For LifeAuthors: NOW Co-Leads & Steering CommitteeNetwork for Ocean Worlds (NOW)The NOW NASA Decadal Astrobiology Research and Exploration Strategy Position Paper (with endorsements)Original postingPreambleOcean Worlds in the outer Solar System, with liquid water oceans in contact with rocky seafloors, represent the highest priority for our community in the search for extant life beyond Earth [1].
Astronomers Find Earth-like Exoplanets Are Common Across The Cosmos

Using the Korea Microlensing Telescope Network (KMTNet), an international team of researchers has discovered that super-Earth exoplanets are more common across the universe than previously thought, according to a new study.
Seismic Velocity Anomalies Suggest Liquid Water At Depth On Mars

This study is jointly completed by Dr. Weijia Sun (Institute of Geology and Geophysics, Chinese Academy of Sciences), Dr. Hrvoje Tkalčić (The Australian National University), Dr. Marco G. Malusà (University of Milano-Bicocca), and Dr. Yongxin Pan (Institute of Geology and Geophysics, Chinese Academy of Sciences). Liquid water plays a crucial role in regulating the habitability of Mars.
Ocean Planet Exploration: Maiden Dive Of The New ROV MARUM-QUEST 5000 Submersible

6 days ago | astrobiology.com | Keith Cowing

The hydrothermal field Menez Gwen was the target location of the first dive of the ROV MARUM-QUEST 5000 at a water depth of about 830 meters. During the dive, which lasted several hours, the team successfully tested the system, took samples and documented everything. During expedition M210 of the METEOR, geochemical and biological samples will be taken from hydrothermal vents along the Mid-Atlantic Ridge in the North Atlantic.
Exoplanet Program Analysis Group - ExoPAG 32 - Meeting

Meeting OverviewNASA’s Exoplanet Program Analysis Group (ExoPAG) meetings are a vital platform where the science community can actively shape the future of exoplanet exploration. By participating in the ExoPAG, you have the unique opportunity to influence NASA by proposing and contributing to Science Interest Groups (SIGs) and Study Analysis Groups (SAGs).
First Detection of Molecular Activity in the Largest Known Oort Cloud Comet: ALMA Imaging of C/2014 UN271 (Bernardinelli-Bernstein) At 16.6 au From The Sun - Astrobiology

6 days ago | astrobiology.com | Keith Cowing

We report observations of comet C/2014 UN271 (Bernardinelli-Bernstein) carried out on UT 2024 March 8 and 17 at a heliocentric distance (rH) of 16.6 au using the Atacama Large Millimeter/Submillimeter Array (ALMA). The CO (J=2-1) line at 230 GHz was detected along with continuum emission from its dust coma and large (βΌ140 km) nucleus, revealing the nature of the activity drivers and outgassing kinematics of the largest Oort cloud comet discovered to date.
Transient Marine Bottom Water Oxygenation On Continental Shelves By 2.65 Billion Years AgoNature Geoscience

6 days ago | astrobiology.com | Keith Cowing

A growing body of evidence suggests that molecular oxygen (O2) accumulated in some shallow marine environments beneath the effectively anoxic Archaean atmosphere 4.0 to 2.5 billion years (Ga) ago. Yet, the temporal and spatial distribution of these oxygen oases is not well known.
Ice Planet Exploration: A Dataset Of Antarctic Ecosystems In Ice-free Lands

1 week ago | astrobiology.com | Keith Cowing

Astrobiology.com Editor’s note: Recently the Fram2 mission took four astronaut explorers on an orbital path that covered both of our planet’s polar regions. This was the fist human mission to orbit Earth at an inclination of 90° i.e. over both the North and South poles. The Fram2 mission was named to honor the Norwegian exploration ship “Fram” which conducted some of the most iconic, initial explorations of Earth’s polar regions.
Statistical Geochemical Constraints On present-day Water Outgassing As A Source Of Secondary Atmospheres On The TRAPPIST-1 Exoplanets

1 week ago | astrobiology.com | Keith Cowing

The TRAPPIST-1 planetary system is observationally favorable for studying if planets orbiting M stars can retain atmospheres and host habitable conditions. Recent JWST secondary eclipse observations of TRAPPIST-1 c rule out a thick CO2 atmosphere but do not rule out atmospheric water vapor or its photochemical product, oxygen. Given the high expected escape rate, maintenance of atmospheric water vapor would require a present-day water source, such as volcanic outgassing.
Temporal Evolution Of Water Abundance In Saturn's Hot Vortex Of 2011-2013

1 week ago | astrobiology.com | Keith Cowing

Water vapour is delivered to Saturn’s stratosphere by Enceladus’ plumes and subsequent diffusion in the planet system. It is expected to condense into a haze in the middle stratosphere. The hot stratospheric vortex (the `beacon’) that formed as an aftermath of Saturn’s Great Storm of 2010 significantly altered the temperature, composition, and circulation in Saturn’s northern stratosphere.
