Object 5 | Carnegie's Dr. Elizabeth Ramsey spent nearly 60 years becoming one of the world's foremost authorities on the human placenta. This diagram of placental circulation by Ranice W. Crosby captures her work. 👇 bit.ly/4cQp4pl #WomensHistoryMonth #Carnegie125

Anat Shahar is presenting "Planetary Habitability: The Origin of Water" tonight @TheHuntington. The free science lecture is SOLD OUT, but you can still tune in online: carnegiescience.edu/planetary-habi…

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. 🥧

Anna Shepard thought archaeology needed the tools of the hard sciences. She was right! Her book, Ceramics for the Archaeologist, was a bestseller on arrival in 1956 & remains a cornerstone of modern archeology. Object 4 | 👉 bit.ly/3P40t6x #Carnegie125 #WomeninSTEM

Meet Henrietta Swope—the Carnegie astronomer whose science and quiet generosity are still shaping discoveries today. 🔗 bit.ly/4sELyOI #WomensHistoryMonth #WomeninSTEM @LCOAstro

🚀 We're back at #AwesomeCon2026 & this year we're putting YOU behind the wheel! Ask smart questions, read the clues, trust your gut, & commit to a space mission…without knowing where you're going. 🗓 Friday, March 13 | 🕑 1:30–2:15 PM | 📍 Room 206 | bit.ly/4bfHpcW

Water may be more common than we ever imagined! Tune in next Monday as Carnegie's Anat Shahar walks us through her groundbreaking research on how water could form naturally in a planet's early years. 📅 March 16 | 7PM PT 📍 @TheHuntington & Online 🔗 bit.ly/4s1wPxp

¿Qué es lo que más les gusta de trabajar en un observatorio astronómico? En este Día Internacional de la Mujer, escuchamos a las mujeres que forman parte del @LCOAstro , quienes, desde distintos roles, contribuyen cada día a explorar el universo.

Every time we point @NASAWebb at something, the universe surprises us. Here are six of the wildest discoveries so far—from teenage galaxies to diamond rain. 🔭 👉 carnegiescience.edu/six-wild-disco…

The Henrietta Infrared Spectrograph will reveal the atmospheres of distant worlds—detecting molecules like water, methane, and more. Built at @CarnegieScience. First light coming soon. Learn more ↓ carnegiescience.edu/unveiling-atmo…

What are distant worlds made of? @CarnegieScience’s new Henrietta Infrared Spectrograph will help answer that—bringing alien planets into sharper focus than ever before. Read the story ↓ carnegiescience.edu/unveiling-atmo…

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-stevens…

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. 🔗 carnegiescience.edu/nettie-stevens…

This Monday (3/2), we're kicking off our #AstronomyLectureSeries @TheHuntington w/ ULTRAVIOLET SUSPECTS. Go back in time with Carnegie's Tony Pahl, who uses UV light from early galaxies to uncover the universe's dramatic beginnings. Learn more 👉 bit.ly/4qZEZow

"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-exoplan…

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!

"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. Q&A: carnegiescience.edu/wanted-exoplan…
