Omani Wells May Shed Light on Martian Methane

Scientists aim to solve that Martian mystery by studying methane-producing organisms living within remote wells in the Middle Eastern country of Oman. The Omani wells go down hundreds of meters beneath the Earth's surface to reach rock layers that store underground water. Such environments, where rocks from our planet’s mantle are in contact with water, could provide clues about the possible past or present habitability of planets such as Mars, says Alexis Templeton, a geologist and microb
