Purdue EAPS Professor Tabb Prissel Honored with NASA Susan Mahan Niebur Award for Groundbreaking Planetary Research

Tabb Prissel, assistant professor in Purdue University's Department of Earth, Atmospheric, and Planetary Sciences, has been named the 2025 recipient of the Susan Mahan Niebur Award. One of NASA's most prestigious honors for early career planetary scientists.

Moisture changes the rules of atmospheric traffic jams

New research from Purdue University reveals how moisture influences atmospheric blocking, a phenomenon that often drives heat waves, droughts, cold outbreaks and floods, helping solve a mystery in climate science and improving future extreme weather predictions.

Decoding Space Rocks with AI: The Meteorite Breakthrough

Securities — Artificial intelligence (AI) is transforming the way we do things, not only on Earth but also in Space. Lead author Marissa Tremblay, assistant professor with EAPS, further noted that meteorites tend to be denser than rocks on Earth, are magnetic and contain metal. However, finding meteorites isn't that easy.

Purdue juniors awarded prestigious 2025 Goldwater Scholarships for excellence in research

Purdue University juniors Deniz Eksioglu and EAPS's Christina Sowinski have been offered 2025 Barry Goldwater Scholarships. This award is the nation’s premier scholarship for undergraduates studying the natural sciences, engineering and mathematics.

Saturn’s moon Mimas may have a vast hidden ocean

PNAS — At first glance, Saturn’s moon Mimas appears dead and boring, with nothing to make it shine. Other moons—such as Enceladus, Titan, and Jupiter’s Europa—harbor icy oceans, lakes of methane, or hints of habitable climates in the past. Mariana Blanco-Rojas, a PhD student in EAPS, presented an explanation of how an ocean layer can exist, even with this lack of smoothing.
