“We observed and mapped multiple plumes of methane on Mars,

Dark central area is region of Syrtis Major Planum, locations of Nili Fossae and Syrtis Major ancient volcano, both emission sites of methane gas plumes. Image by Hubble.Yellow circles at Nili Fossae and southeast quadrant of Syrtis Major, ancient volcano, mark where NASA and the European Space Agency (ESA) have measured large quantities of methane emissions since 2003. The persistent size of methane quantities imply a continually replenishing source. Is it geological? Or biological? Map created by Alwyn Botha, www.the-planet-mars-com.
