Photos below sent to me from Andrew Ryan, graduate student at Arizona State University’s School of Earth & Space Exploration. He co-authored an article that revealed evidence of lava coils on Mars (click here for my earlier blog about this today). I asked Ryan for photos (being as I’m from the Big Island of Hawaii where the active volcanoes are) and here’s what he sent me. First two of Mars, taken by NASA/JPL/University of Arizona, and the last one of Hawaii is courtesy of USGS.
The article about this discovery in Science is co-authored by ASU Regent’s Professor of Geological Science Philip Christensen.
