A Whole-planet Model Of The Earth Without Life For Terrestrial Exoplanet Studies
As the only known habitable (and inhabited) planet in the universe, Earth informs our search for life elsewhere. Future telescopes like the Habitable Worlds Observatory (HWO) will soon look for […]
Dale Andersen’s Astrobiology Antarctic Status Report: 1 February 2026: Drilling Diving Holes
Dale: Hi Keith, We’ve had a productive few days since I last checked in. Yesterday and today we worked on the eastern slopes adjacent to the Anuchin Glacier – Denis […]
Exoplanet Candidate HD 137010 b: An Ice-Cold Earth Analog?
The Discovery A candidate planet that might be remarkably similar to Earth, HD 137010 b, has one potentially big difference: It could be colder than perpetually frozen Mars. See A […]
Setting A Polyphasic Approach To Study Antarctic Cryptoendolithic Communities As A Toolkit For Astrobiology
The present study has set up a pilot experiment to optimise the most promising assays for investigating the survival of Antarctic microbial cryptoendolithic communities – a natural astrobiological benchmark – […]
The Microbial Inhabitants of the Corona Lava Tube: Astrobiological Insights from a Mars Analog Environment
Lava tubes are recognized as strategic targets in the search for life on Mars. The Corona Lava Tube System in Lanzarote serves as a terrestrial analog for martian subsurface environments […]
Dale Andersen’s Astrobiology Antarctic Status Report: 24 January 2026: Lake Untersee Base Camp Weather Conditions and Forecast
Keith’s note: A quick snapshot of the weather at Lake Untersee and A forecast for the coming week. Dale’s team has a small Ambient WS-4000 weather station set up near […]
Dale Andersen’s Astrobiology Antarctic Status Report: 21 January 2026: Lake Untersee Base Camp Weather
Hi Keith, The past couple of days brought low clouds, some drifting snow, and steady winds that peaked around 30 m/s (~67 mph).
Ice World Assay: Ancient Antarctica Reveals A ‘One–two Punch’ Behind Ice Sheet Collapse
Editor’s note: there are currently two advanced missions heading for the jovian system – Europa Clipper and ESA Juice – to study icy Europa and the other icy worlds orbiting […]
Dale Andersen’s Astrobiology Antarctic Status Report: 18 January 2026: Lake Untersee Base Camp Is Operational
Keith: We just completed the camp last night, and today a storm will move in with 50 mph winds (more?) and perhaps some snow. Should provide a quick test of […]
