Dale: A partial eclipse over Lake Untersee yesterday—an ordinary piece of celestial clockwork that felt anything but ordinary from the icy shores of Lake Untersee in the mountains of Antarctica. […]
What Cold-water Geysers On Earth Reveal About The Habitability Of Ocean Worlds
In the eastern Utah desert, carbon-dioxide-saturated water bubbles, sprays and foams from the ground. These cold-water geysers, sometimes called ‘soda pop geysers,’ are a new and reliable Earth-based analog for […]
Dale Andersen’s Astrobiology Antarctic Status Report: 15 February 2026: Diving Under The Ice At Lake Untersee
Keith, Sorry for the quiet—our days have been packed, and out here every usable hour feels borrowed. Since my last report the weather has changed its mind a few times. […]
Conceptual Challenges In Astrobiological Analog Environments And Paths Toward Resolution
Analog environments are terrestrial environments that resemble extraterrestrial sites; this concept originated in space sciences for defining methods to study planetary geology, training for missions and testing research instruments.
Planetary Analog Sites In The Indian Subcontinent And The Indian Ocean: Underexplored Environments Suited For Astrobiological And Space Research
Astrobiology seeks to understand the origin, evolution, distribution, and future of life in the Universe, focusing on habitability beyond Earth.
