Not every rivalry at Carnegie goes through peer review. 🏓 👀 Postdocs come from around the world & stay only a few years, so the community has to grow fast. At EPL, that's what ping-pong is for! Our #Carnegie125 object for #PostdocAppreciationWeek 👇 https://bit.ly/3TPcIqk

Object 23 | The Ping Pong Table

For years, a ping-pong table has been quietly bringing people together at the Earth and Planets Laboratory. This object was specially chosen for Postdoc Appreciation Week.

As #PostdocAppreciationWeek wraps up, we want to say thank you to our postdocs! Your curiosity, drive, & talent energize all of Carnegie Science's campuses. From Carnegie President John Mulchaey: "It's our honor and privilege to call you colleagues." Applications are open! https://bit.ly/4hN2ujm

The telescopes at Las Campanas may stay up in the mountains, but this lab is on the move! Object 22 of #Carnegie125 is Las Campanas Observatory's LabMóvil, a 30-foot mobile lab bringing hands-on astronomy to schools across northern Chile. Read more: https://bit.ly/4yd9mwk

📢 We're thrilled to announce that astronomer Guillermo Blanc has been named Director of Carnegie's Las Campanas Observatory in Chile—home of the twin Magellan telescopes & future site of the Giant Magellan Telescope. Full Press Release👇 bit.ly/4rKfU3f

Happy #InternationalMicroorganismDay! 🦠 Meet Chalmy (Chlamydomonas reinhardtii), the tiny green alga in our logo. Carnegie plant scientists have studied it for decades to probe big questions about photosynthesis. See how Carengie's Adrien Burlacot uses it today: https://bit.ly/4he1VOa

In October, Moh El-Naggar joins Carnegie as the director of our Biosphere Sciences & Engineering division (BSE). He steps into the role just as our biologists set up new labs on the @caltech.edu campus as part of our relocation to Southern California. 🧵

Congratulations, Prof. Moh El-Naggar! We look forward to seeing you thrive in this new role and to building an even stronger partnership with @carnegiescience.bsky.social. dornsife.usc.edu/news/stories...

🖖This just in! Philip Plait—astronomer, author, and the internet's "Bad Astronomer"—will be moderating the panel at our upcoming #NeighborhoodLecture celebrating sixty years of Star Trek! Free and open to the public! Register today to secure your spot: bit.ly/4qGF8ig

What did Star Trek get right about alien worlds? On Sept. 9 (a day after the show turns 60) astrobiologist Mike Wong will compare Trek's fictional worlds to actual exoplanets we've found. (No Risa yet.🤞) Panel and Q&A to follow. 🖖 #LLAP 📍 Washington, DC 🕕 6:30 pm 🎟️ bit.ly/4gH7wNH

🚐🌵 In the 1970s, Carnegie scientists drove a mobile home into Death Valley. The lab on wheels helped study a plant that did its best photosynthesis at 117°F. The Desert Mobile Lab (+ this very 70s photo set) make up our 20th #Carnegie125 object. Full Story 👉 https://bit.ly/4x3bo1x

🌐 🚩 We're flying high with #Carnegie125 Object 19! Carried over oceans, across continents, and even into space, our expedition flag tells the story of an institution dedicated to exploration. Learn how this maritime flag became an institutional icon: https://bit.ly/4hVGyD9

Last week, Carnegie President John Mulchaey & author George Hammond joined the Commonwealth Club to discuss science history, next-gen telescopes (bit.ly/4hjbyNk), & the future of U.S. astronomy. The big takeaway? Continued U.S. leadership requires longterm investment. It's a decision—not a given!

🎂 Happy Birthday! Carnegie astronomer Vera Rubin was born on July 23, 1928. She saw that stars at Andromeda's edge orbit as fast as those near its center—evidence of dark matter holding things together. Our special birthday logo is based on Andromeda, naturally. 👉 bit.ly/4fxYgty

Happy birthday to Robert S. Woodward—Carnegie's second president and "the first modern manager of science." His portrait is Object 18 in our #Carnegie125 series. Learn how his approach got Andrew Carnegie to double down on his investment in science. ⬇️ bit.ly/4yyTk0c

We've got another cool find from our archives! 🔭 In 1968, a Carnegie team hiked a bare Chilean peak above the high Atacama to decide if it would be a good home for an observatory. This collection of photos captures their trip. Object 17 in #Carnegie125: bit.ly/4fl8Jsg

A team led by @harvard.edu's Collin Cherubim & including Carnegie's Shreyas Vissapragada caught helium leaking from the atmosphere of a rocky planet orbiting in its star's habitable zone—making LHS 1140 b the first exoplanet with an atmosphere that could hold liquid water! 💧 🌏 🤯 👉 bit.ly/4pq6Yif
