An article published in the journal “Journal of Geophysical Research-Planets” describes a research on the traces of ancient volcanic events that may have affected the climate of the planet Mars. Using data collected by NASA’s Mars Odyssey space probe, a team of researchers led by Don Hood from Louisiana State University (LSU) studied an unusual region of Mars that was called Greater Thaumasia concluding that the mountain ridges that surround it are probably of volcanic origin.
