International study discovers ancient meteoritic impact over Antarctica 430,000 years ago

A Florida State University geochemist and postdoctoral scholar were part of an international research team that has found new evidence of a low-altitude meteoritic touchdown event reaching the Antarctic ice sheet 430,000 years ago. The geological record has long shown evidence of meteorite collisions with Earth, but scientists had previously only known of two airbursts […]

FSU expert available for context on NASA Perseverance mission

Once on Mars, the rover will search for signs of ancient microscopic life and collect data about the planet’s geology and climate. Perseverance will be the first rover to collect and store […]

FSU MagLab geochemists solve mystery of Earth’s vanishing crust

Thank goodness for the Earth’s crust: It is, after all, that solid, outermost layer of our planet that supports everything above it. But much of what happens below that layer remains a mystery, including the fate of sections of crust that vanish back into the Earth. Now, a team of geochemists based at the Florida State […]
