Chemical Guidebook May Help Mars Rover Track Extraterrestrial Life
To help a NASA rover eventually hunt for life on Mars, scientists are writing a chemical guidebook to aid the search for extraterrestrial life. Using new imaging tools and earthly […]
The Zöe Rover: Robotic Astrobiology Expedition Yields Significant Science Findings
A group of scientists announced today that they identified habitats and microbial life using a rover in Chile’s arid Atacama desert, one of the harshest environments on Earth, and that […]

January 17th, 2005 Anticipation Comparisons of New Zealand to Purgatory are probably not that common. Nevertheless, for the past two weeks, this is exactly how it has felt. Christchurch, New […]
What Is Life – and How Do We Search for It in Other Worlds?
I need a “tricorder”—the convenient, hand-held device featured on Star Trek that can detect life forms even from orbit. Unfortunately, we don’t have a clue how a tricorder might work, since life […]
Major Milestone For Detecting Life On Mars
“To detect life on Mars, we have to devise instruments to recognize it and design them in such a way to get them to the Red Planet most efficiently,” said […]
Researchers Uncover Extreme Lake — and 3000-Year-Old Microbes — in a Mars-Like Antarctic Environment
NSF-supported researchers drilling into Lake Vida, an Antarctic “ice-block” lake, have found the lake isn’t really an ice block at all. In the December 16 issue of the Proceedings of the […]
