Icy impacts: Gauging thickness of ice on Europa brings science closer to finding possibility of life

Europa, one of Jupiter’s rocky moons, is home to huge saltwater oceans and thought to be a potential home to nonterrestrial life — but this search for life is dependent on scientists knowing the depth of the icy shell encasing Europa’s entire surface.  

Brandon Johnson’s lab has been able to determine the depth of that shell using his expertise in crater modeling.

Scientist: Brandon Johnson, associate professor of planetary science, “Impact Cratering”

Rover captures a Martian eclipse. Perseverance team lead at Purdue explains

The Perseverance rover recently captured images of a solar eclipse on Mars. In this video, Briony Horgan explains the science behind eclipses on Mars, Earth and other planets — and why Earth’s eclipses are particularly special.

Cloudy science, clear insights: Atmospheric scientist studies clouds’ causes and effects

Alexandria Johnson’s expertise in cloud physics provides vital information to many fields, from the way microplastics are affecting weather patterns to the study of faraway exoplanets.

After the most powerful telescopes have reached across the universe, sometimes Johnson’s ability to parse an exoplanet’s own densely clouded sky is the best way to see what’s happening on the farthest of these celestial bodies.

“If we want to understand these enshrouded exoplanets, we need to understand the clouds. That understanding gives us insights into the atmospheric chemistry at work, atmospheric circulations and the climate of these exoplanets,” Johnson says.

Boilermakers get rare opportunity to conduct research at the Mars Desert Research Station in Utah

For two-week terms, teams commit to living in a compact habitat in Utah’s remote red dust desert — conserving their resources and conducting research designed to address real-life situations that future missions to Mars may face.

“To have something like MDRS, where you’re actually getting exposure to practical problems that some space missions would face, is a phenomenal opportunity,” says Jesus Meza Galvan, a PhD student in aerospace engineering. 

About Purdue University

Purdue University is a public research institution demonstrating excellence at scale. Ranked among top 10 public universities and with two colleges in the top four in the United States, Purdue discovers and disseminates knowledge with a quality and at a scale second to none. More than 105,000 students study at Purdue across modalities and locations, including nearly 50,000 in person on the West Lafayette campus. Committed to affordability and accessibility, Purdue’s main campus has frozen tuition 13 years in a row.
