An exciting new development in planetary exploration was announced today: NASA has chosen the science instruments which will be included in a new mission to Jupiter’s moon Europa. […]

Researchers Develop New Technique to Search for Chemical Evidence of Life on Mars

Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, […]
