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 […]

Volcanic Activity Linked to A Warm and Wet Ancient Mars

November 17, 2014

Exploratory missions to Mars, such as NASA’s Curiosity Rover, have provided more and more evidence that Mars at one time was warm enough for water to flow on its surface. Now a new study published in the journal “Nature Geoscience” has found that those ancient, warm periods on the Red Planet probably took place in […]
