Boron, a chemical signature of evaporated water, has recently been discovered on the surface of Mars, and this suggests that the Red Planet has the potential for long-term habitable groundwater in the ancient past.
The NASA Glenn Research Center is teaming up with the University of Michigan to develop a new high-tech instrument called Martian Aqueous Habitat Reconnaissance Suite (MAHRS), which is designed to fine evidence of alien life on Martian waters.
A recent study suggests that nitrogen in billion-year-old rocks could potentially become bio-signature of life on Mars.
A new study suggests that Mars was once wetter and warmer based on studying the images taken by ESA's Mars Express and NASA's MRO.
Scientists find strange funnels and depressions on the surface of Mars interesting as they present a good site to search for alien life.
