Except, if I understand them correctly: they don't know what the Sahara's core is made of and might supply for life, to keep the analogy Not that that makes it likely to be hospitable. I'm only surprised by the headline because I wouldn't have thought anyone had expected anything different, so a headline like "as uninhabitable as you might figure" would have made more sense, but nevertheless this doesn't rule it out to about the same extent as it wasn't deemed unlikely already in my perception (as a follower of space news)
