Astrobiology Analog: Danakil Depression Reveals Extreme Environment Clues
Introduction: Danakil Depression as a prime astrobiology analog The Danakil Depression in northeastern Ethiopia is one of Earth’s most extreme landscapes. Its scorching temperatures, acidic springs, and salt flats create conditions that echo the harsh environments scientists expect on other planets and moons. In astrobiology, the ability to study such analog sites helps researchers infer…

A Flash, a Boom, a New Microbe Habitat: Life After an Asteroid
Introduction: When a Cataclysm Opens a Microbial Door Asteriod impacts are planetary scale events that typically wipe out surface life. Yet, beneath the dust, debris, and heat, a different story can unfold: the formation of new habitats where microbes might cling to life in the aftermath. This paradox—catastrophe fostering opportunity—drives a growing field of research…

Liquid Water on Ryugu Reveals a Billion-Year-Old Secret
Liquid Water on Ryugu: A Hidden Water Trail Across Time A recent study of tiny rock fragments returned from the asteroid Ryugu by JAXA’s Hayabusa2 spacecraft has upended assumptions about when and how water could move through asteroids. The research, involving scientists from the University of Tokyo among others, shows that liquid water once traversed…
