Pi shows up anywhere nature curves, rotates, or radiates. When you study everything from Earth's core to exoplanets to how plants grow, it's basically everywhere.
Happy #PiDay from Carnegie Science. 🥧
🚀 The Earth & Planets Laboratory is headed to #AwesomeCon2026, and this year, YOU'RE in the captain's chair!

This month, we'll be sharing more of the objects, stories, and women that shaped our first 125 years. Stay tuned! #Carnegie125 🔗 carnegiescience.edu/nettie-steve...
In 1904, Carnegie Science awarded Nettie Maria Stevens for the "Investigation of problems related to Sex Determination." Her findings proved that X and Y chromosomes—not environment—determine biological sex.
It's #WomensHistoryMonth, and we're kicking it off with object No. 3 in our #Carnegie125 series: a $1,000 grant application that helped change biology forever.

"Even though the planets that are the focus of my work are not anyplace someone would want to live, they are still interesting for thinking about how habitability evolves."
Read the full Q&A with Shreyas Vissapragada: carnegiescience.edu/wanted-exopl...
But in the case of the rare exoplanets that Vissapragada studies, nature has done the work for us by literally removing the atmosphere of a gas giant and exposing its bare core.
Thanks, nature!
"Historically, one of the most challenging things to learn about a planet is its interior, " says Vissapragada.
We're still learning about Earth's interior...and we live here! Gas giants—let alone exoplanet gas giants—are on a whole other level of hard to read!
For example, he looks at Neptune-sized planets that have had their atmospheres literally boiled away into space, leaving an exposed core.
The planets he studies are not the ones we would go to look for life since they're busy being irradiated, having their atmospheres stripped away, or undergoing some other extreme planetary activity.
Yet their strangeness is precisely what can teach us about habitability!
"Yes, I'm always a fan of drama." - Shreyas Vissapragada, Hale Scholar, Carnegie Science
Vissapragada's research aims to uncover the complex life stories of exoplanets—and he has a particular interest in worlds with dramatic backstories.

“We contend that evolution is a universal phenomenon, in play since the Big Bang.”
In Time’s Second Arrow, Carnegie's Robert Hazen and Michael Wong argue that complex systems—from atoms to life—evolve toward greater functional information.
