Forget Mars and Europa — NASA is hunting life on this unthinkable little world
07-01-2025
The Pulse — NASA is constantly searching for any signs of life in the solar system. Earth is currently the only planet that is capable of holding life as we know it, as the distance between it and the sun is perfect for life to proliferate. Now, they are turning their focus to somewhere else to see if there’s something vital for life. A team led by Ian Pamerleau, a Ph.D. student at Purdue University, worked with his supervisor, Mike Sori, and Jennifer Scully from NASA’s Jet Propulsion Laboratory.

Ceres: The asteroid belt’s forgotten ocean world
06-24-2025
Big Think — Dawn data showed that Ceres’ density is quite low, suggesting a high overall water (rather than rock) content. That seemed inconsistent, however, with the general lack of shallow craters and the observation that deep craters are very well preserved. Recently, following a paper published in Nature Astronomy by EAPS's Ian Pamerleau and colleagues from Purdue University and the Jet Propulsion Lab, we found a solution to this apparent mystery.

Mysterious Mars Rock Leaves Scientists Searching For Origin Clues
04-23-2025
Forbes — The Perseverance rover is currently exploring the rim of the Jezero Crater in an area called Witch Hazel Hill. The rover took some time in April to study a spot where lighter and darker rock outcrops meet. That’s where the unusual rock came into focus. Margaret Deahn, a PhD student in EAPS, is featured in the Forbes article.

NASA finds mysterious skull-shaped feature on Mars — where star-gazers say it doesn’t belong
04-21-2025
New York Post — NASA’s Mars rover has spotted something out of this world — a mysterious, skull-shaped elevation – sitting on a slope where star-gazers say it doesn’t belong. The mysterious rock – dubbed “Skull Hill” was discovered April 11 by the Perseverance rover while it was driving down a ridge called Witch Hazel Hill.
