Why? NASA is a crown jewel of US science and an international inspiration. Its logo adorns hoodies worn by young and old. The most famous telescopes could not have existed without Goddard and shutting down parts of it, even temporarily, cuts off the life blood for future missions. Why kill NASA?!?

PRESS RELEASE DAY! Could not be prouder of this result and so happy that it's now out!!! 🤩✨ Thanks to the team at @stsci.edu for the wonderful write-up and image!

#NASAWebb has found the first direct evidence of potential moon formation around a giant exoplanet. The discovery is shedding light on how such systems evolve and why moons could be potentially habitable worlds: https://bit.ly/46xGodN 🔭 🧪

An illustration of a young planet with a surrounding disk of dust and gas potentially forming moons. The planet, which appears dark red, is shown at lower right, circled by a cloudy, clumpy reddish orange-colored disk. The host star appears at upper left, and glows yellow, with its own reddish disk of debris. The disk that surrounds the planet takes up about half the illustration. The black background of space is speckled with stars. At the bottom of the illustration, graphics of molecules are listed in the following order: Acetylene, Carbon Dioxide, Ethane, Benzene, Hydrogen cyanide. The words Artist’s Concept appear at upper right.

TOMORROW: Two talks, one big night of discovery! Join Earth & Planets Laboratory postdocs Sierra Grant & Shubham Kanodia as they reveal how planets are born—and the giants that defy the rules. #NeighborhoodLecture 📅 Sept 25 | 6:30 PM ET | DC & Online 🔗 RSVP: carnegiescience.edu/birth-worlds...

Birth of Worlds, Rise of Giants

Join Carnegie postdocs Shubham Kanodia and Sierra Grant as they explore the secrets of distant worlds—from the birth of new planets to giant rule-breakers that defy expectations—in a special double…

Great work by Kielan Hoch and team on this incredible two-planet system!! We will revisit this target with MIRI-MRS next year to hunt for molecules in the disk around planet b, in a program led by Gabriele Cugno and me, and with Kielan's expertise on the system 🥳🪐
