Volcanic Activity Created Martian Geological Oddity

June 19, 2018

Scientists have long been puzzled by a mysterious formation located near the equator of Mars called Medusae Fossae. A new study from a pair of scientists – Lujendra Ojha and Kevin Lewis – at the Johns Hopkins University in Baltimore suggests that the large deposit of soft rock was probably formed as a result of violent volcanic eruptions that […]
