What a night! Thank you to everyone who joined us at PSI HQ for International Observe the Moon Night! Here’s a look back at some of our favorite moments. 🌕💫

When did early Earth become stable enough for life’s chemistry to persist? New research, published in @Nature.com and co-led by PSI scientist Oleg Abramov, points to around 4.33 billion years ago, when declining impacts allowed increasingly stable environments to emerge. 🔗 : buff.ly/CAbqnlV

🌕 Keep the Moon celebration going! This week’s PSI Weekly Briefing explores the Moon’s formation, spotlights PSI co-founders Bill Hartmann & Don Davis, and features Hartmann’s lunar art. 🎨 Read the latest + subscribe for more planetary science: buff.ly/bzLGXEv

What does the Moon mean to you? 🌓 PSI Co-founder Bill Hartmann shared how the Moon changed his life. We're so excited to celebrate the Moon tonight during International Observe the Moon Night. Join us in Tucson, Denver, or online. Details: buff.ly/F3DiMwf #ObservetheMoon

PSI Co-founder William Hartmann is both a planetary scientist and accomplished space artist, using his scientific understanding to help bring other worlds to life. Explore some of his visions of the Moon. ⬇️ See some of these pieces in person at PSI 9/19! Details: buff.ly/Jg9CDTw #SciArt

You don’t have to be a planetary scientist to do planetary science! PSI’s World Mappers lets anyone help study the Moon by identifying features in real lunar images. Start mapping: buff.ly/YcKFyQV Come explore the Moon with us at Tucson HQ on 9/19! 🔭 Details: buff.ly/Jg9CDTw

"Growing up, I was always interested in science. I had a chemistry set, a microscope (but not a telescope!), watched all the science documentaries I could find..." Read the full Q&A with Senior Scientist Henry Hsieh in our Weekly Bulletin! buff.ly/RVQ6Kv3

This week's #SciArt is wearable! Not only is PSI's Pamela Gay a scientist, researcher & communicator, she's also an artist. This beautiful pendant, Cerulean Stillshot Among the Stars, is just one example of how she interprets the beauty of the universe.

50 years after Viking landed on Mars, what have we learned about the search for life, and where do we go next? PSI Senior Scientist David Grinspoon joined @CosmoQuest to talk Mars, astrobiology, Venus, and the future of planetary exploration. 🎥 buff.ly/N8GFOIJ

Viking: Chasing Astrobiology then and now with David Grinspoon

In 2026, we are seeing a number of 50 year anniversaries for the Viking 1 and 2 missions to Mars. From their landings in August and September 1976, to the first astrobiology reports in December 1976,…

This week's #PlanetaryPet is Roxie! Bossy Roxie makes sure to speak up when she wants a snack or wet food. Roxie is what PSI’s Kat Volk describes as “semi-feral.” Kat says Roxie’s favorite hobbies include hissing at Kat and gently smacking Kat’s hand if the food service isn’t quite fast enough.

PSI Director and CEO Amanda Hendrix spoke with NPR about changes to federal science advisory committees and why they matter. The committees allowed NASA leaders to “hear almost directly from the community,” Hendrix said. Read more: buff.ly/LGFkI7O

The U.S. relied on these science advisers. Then the Trump administration cut them

The federal government recruits top experts to volunteer to advise on pressing research issues of the day. Since President Trump took office, hundreds of these experts have been dismissed.

Don't forget - NASA’s Nancy Grace Roman Space Telescope is scheduled to launch tomorrow at 7:26 a.m. EDT (4:26 a.m. PDT)! With a field of view at least 100x larger than Hubble’s, Roman will give scientists an extraordinarily wide view of the universe. Follow the launch: buff.ly/fF8f1g3

TONIGHT: PSI Senior Scientist Jeffrey Kargel is scheduled to join Anderson Cooper at 8pm ET on @CNN.com to discuss the devastating disaster in the Himalayas. Kargel has spent decades studying glaciers in the region and will outline the science behind this destructive event.

Roman will look deep into the universe. But thousands of objects in our own Solar System will cross its view along the way. PSI’s Susan Benecchi is helping make sure scientists can study them, potentially revealing new clues about the building blocks of planets.

Our thoughts are with all affected by the devastating flooding and debris flows in the Himalayas. Initial assessments indicate a collapse of rock and ice triggered the destructive flow. PSI Senior Scientist Jeff Kargel briefed the Nepali PM on the science behind the event. More: buff.ly/UtQoHWO

Glacier collapse may have triggered 'almost incomprehensible' Nepal flood

Scientists don't yet know exactly what triggered the Nepal flood, but they suspect a glacier collapse and suggest climate change also played a role.
