Sign Up to like & getrecommendations! Published in 2019 at "Journal of Earth Science"
DOI: 10.1007/s12583-019-1212-2
Abstract: Over 600 chloride-bearing deposits (chlorides) have been identified on the southern highlands of Mars. These chlorides have critical implications for hydrology and astrobiology: they are indicators of an evaporating super saturated solution, and they could… read more here.

DOI: 10.1017/s1473550419000247
Abstract: Abstract Photosynthesis offers a convenient means of sustaining biospheres. We quantify the constraints for photosynthesis to be functional on the permanent nightside of tidally locked rocky exoplanets via reflected light from their exomoons. We show… read more here.
