Happy #FallEquinox! 🍂 Today, the Sun crosses Earth’s celestial equator, marking the official start of autumn in the Northern Hemisphere. It's also the time of year when day and night are nearly equal in length around the globe.
At the Science Center, the planetarium has reopened with a first-of-its-kind star projector, immersive digital technology, and a mission to inspire visitors to keep looking up. laduenews.com/health-and-wel…
Did you know you can often spot the Moon in broad daylight? 🌙 And that some thunderstorms can produce 100+ mph winds without a tornado? ⛈️ This month's #DaySkyUpdate explores both, plus what to watch for as we approach the September Equinox. Read more:slsc.org/day-sky-update-sept…

Look up tonight.
The Moon will pass through Earth's shadow during a deep partial lunar eclipse visible from much of North and South America and parts of Europe and Africa. As the eclipse deepens, the Moon will appear tinged with shades of red and copper.
ALT A nearly total partial lunar eclipse fills the center of the frame against a dark sky. The Moon is bathed in shades of red, orange, and copper as Earth's shadow covers most of its surface, leaving only a thin, bright crescent illuminated along its left edge. Dark lunar maria and lighter highlands remain visible through the reddish glow. The image was captured during the November 19, 2021, partial eclipse of the full Beaver Moon, the longest partial lunar eclipse in centuries. Credit: NASA
NASA honors the memory of Dolly Parton, who passed away on Aug. 25, 2026.
In 1989, Dolly performed at @NASAJohnson's Rocket Park, alongside fellow musicians Willie Nelson and Kenny Rogers, to an audience of over 12,000 NASA employees and their families.

#FunFactFriday: A day on Venus is longer than a year on Venus! 🔭 Venus takes about 243 Earth days to rotate once, but only 225 Earth days to orbit the Sun. ☀️ For comparison, Earth rotates once every 24 hours, while Mars takes about 24 hours & 37 minutes. 🌏
Exciting morning at @FOX2now!
Thank you Brittany Kyles for having us & the @STLScienceCtr to talk about our upcoming heart care pop-up ❤️🧑🔬
Catch us on the air again at noon or on fox2now.com/
Come see us at the @STLScienceCtr on Aug. 15!🧑🔬
We look forward to educating our community on heart disease, available treatments, & advanced technologies. We’ll be joined by local cardiologists. Stop by to learn more & test-drive the #GenesisX robot in phantom telesurgery. 🧑⚕️🫀
#DidYouKnow Raindrops aren’t tear-shaped! 💧 Small raindrops are nearly spherical thanks to surface tension. As they grow larger and fall faster, air resistance flattens them into a shape more like a hamburger bun. 🌧️ #FunFactFriday
Listened to my friend Bob McCarthy (@sluhjrbills grad) speak last night about all things sound….The Wall of Sound he helped Owsley w and the recent Metallica tours @MeyerSound was tasked with. Fascinating content! Thanks @STLScienceCtr for the Awesome “Up Late” event!
🚨 SAVE THE DATE 🚨 On Oct. 3, Club WONDER returns for a night that's light years ahead of your typical gala. ✨ Explore the Science Center after hours, enjoy cocktails and bites, dance beneath the stars, & help spark curiosity for generations to come. 🎟️ slsc.org/club-wonder-light-y…
There is more than meets the eye in this photo…
The ring around the central galaxy cluster is evidence of dark matter, the invisible glue holding the universe together. Dark matter doesn’t emit, reflect, or absorb light, but it has gravity like ordinary matter. 🧵
