We’re kicking off the countdown to #Carnegie125 next year! To celebrate, we're opening the archives to share 125 objects that tell our story of scientific excellence. 📸 Object 1 On this day in 1902, Andrew Carnegie convened our first Board of Trustees—founding Carnegie Science. #HBDCarnegieScience

🎉 It’s #CarnegieScienceDay! For 124 years, we’ve advanced discovery by bringing together ideas, disciplines, and people to study humanity’s biggest questions. Because breakthroughs don't come from staying in one lane. Explore how → bit.ly/carnegie-science-day #HBDCarnegieScience

They're not like us! More than 6K exoplanets have been discovered—and many don’t resemble anything in our Solar System. Carnegie astronomer Shreyas Vissapragada explores exoplanet atmospheres to uncover the clues to habitability. 👉 bit.ly/49LwV5B #HBDCarnegieScience

“No organisms in this world live by themselves.” Carnegie scientist Yixian Zheng studies how 🪸 depend on 🦠 living inside their cells—and what happens when that partnership breaks down. https://bit.ly/4a8jRq2

POV: You walk into a physics lab and see someone firing protons...at frog eggs? Welcome to Carnegie in the 1940s, where nuclear physics smashed into biology and sparked a whole new field. #ScienceHistory https://carnegiescience.edu/news/atoms-cells-history-biophysics-section

When a group of nuclear physicists decided to study life instead of atoms, everything changed. Their interdisciplinary leap helped shape the rise of modern molecular biology. Here’s how it happened ↓ https://carnegiescience.edu/news/atoms-cells-history-biophysics-section

We’re excited to announce that astronomer Michael R. Blanton has been named the 12th Director of the Carnegie Science Observatories! He joins us from New York University, where he served as Director of the Center for Cosmology and Particle Physics. (1/5) Full Press Release👇 buff.ly/JZ0J81w

New PNAS study shows that life’s signature lingers in rocks long after the original biomolecules are gone. Hazen, Wong (@miquai.bsky.social) & Prabhu (@anirudhprabhu.bsky.social) found chemical traces of ancient life in 3.3 BYO rocks. Let’s get into it. (1/6) 👉 carnegiescience.edu/chemical-evi...
