Mars Crater May Actually Be Ancient Supervolcano

  A research project led by Joseph R. Michalski, Senior Scientist at the Planetary Science Institute, has identified what could be a supervolcano on Mars – the first discovery of its kind. New research suggests the Eden Patera basin on Mars could have been formed by an explosive volcanic eruption, not the impact of a [continue reading]

Volcanoes on Jupiter's Moon Io are in the Wrong Spot

  Jupiter’s moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high (about 400 kilometers). However, concentrations of volcanic activity are significantly displaced from where they are expected to be, based on models that predict how the moon’s interior is [continue reading]

Organic Carbon In Meteorites From Mars Is Not Biological

  Molecules containing large chains of carbon and hydrogen–the building blocks of all life on Earth–have been the targets of missions to Mars from Viking to the present day. While these molecules have previously been found in meteorites from Mars, scientists have disagreed about how this organic carbon was formed and whether or not it [continue reading]

Ancient Volcanic Blast Provides More Evidence of Water on Mars

  The atmosphere of Mars is less than 1 percent the density of Earth’s. It’s one of the reasons liquid water covers much of our planet but cannot exist on the Red Planet. As more research points toward the possibility of water on early Mars, scientists have increased their studies on the density of its [continue reading]

Scientists Discover Volcanic Activity In Moon’s Tycho Crater

  Breaking through a popular perception of moon being a geologically inert place for the last three billion years, Indian scientists have found new evidence of the recent volcanic activities inside a lunar crater, opening up a new window for research.   Recent findings from Chandrayaan-1, and NASA’s Lunar Reconnaissance Orbiter (LRO) show evidence of [continue reading]

Mars' Vast Fields of Glass

The surface of Mars exhibits numerous lava flows and other signs of effusive volcanism. Although models suggest that explosive volcanism should also have produced extensive deposits, direct evidence for large-scale explosive volcanism has been scarce.A new study by Briony Horgan and James F. Bell III at Arizona State University of the mineralogy of dark regions [continue reading]
