It’s #NeighborhoodLecture night at the Earth & Planets Laboratory! Join NASA astrobiologist and author Dr. Caleb Scharf (@calebscharf.bsky.social) for The Giant Leap—a look at how humanity’s move into space could reshape life itself. ⌛6:30 PM | NW DC | There's still time to RSVP! 🎟️ bit.ly/4qxBBT7

From spying on baby planets to gas giants that shouldn’t exist, our last #NeighborhoodLecture was a rare double feature on the extremes of world-building—told by two Carnegie postdocs. 🎥 Recording + recap: bit.ly/43VgArv #PostdocAppreciation

For the 1st time in 4 billion years, life has escaped its home planet! Join NASA Ames astrobiologist @calebscharf.bsky.social as we venture into the void to see how space exploration is reshaping our next great leap. 🗓️ 11/6 | 6:30 PM EST 📍 Carnegie Science, NW DC & Online 🎟️ RSVP → bit.ly/4qxBBT7

How do planets get wet? 💦 A new study in @Nature, led by Carnegie’s Anat Shahar & #CarnegieAlum Francesca Miozzi (now at @ethz.ch), shows that water can form naturally during planet formation when hydrogen-rich atmospheres meet molten rock. No comets required. (1/9) 👉 bit.ly/48QEOXr

At Carnegie Science, we study the origin and evolution of everything, says President John Mulchaey. Our expertise builds connections between the origins of "star stuff," the formation of planets, the rise of life, and the search for life elsewhere.

Thank you to the 500+ guests who joined us for a day of discovery at our first-ever #EPLOpenHouse. It was a blast—literally! 🌋 Your curiosity made the day shine, and we can’t wait to do it again next year! Until then, check out our upcoming events: 👉 https://bit.ly/43vMivk

A newly discovered asteroid travels around the Sun in just 128 days—the second-fastest unique asteroid orbit in the Solar System. First observed by Carnegie's Scott Sheppard, the asteroid—called 2025 SC79—was found hiding in the Sun’s glare. carnegiescience.edu/news/fast-mo...

The application portal for the next wave of @carnegiescience.bsky.social postdoctoral fellows is open through November 3. I hope you’ll consider joining us 🚀
