🕷️ Scientists just discovered two new sea spider species in the Salish Sea, including a hairy-legged, red-eyed one. Just in time for spooky season!

You can’t step on Venus without a spacesuit. 🌡️🪐 Kyle Horn of @MITAeroAstro explains that with 90 bar of pressure and temperatures of 450°C, the surface could turn lead into liquid. But if you were in the middle atmosphere, 55 kilometers up, you could step outside with just an oxygen mask and good sunscreen to catch a Venusian breeze. Up there, gravity is about 90% of Earth’s, radiation is milder than in the upper atmosphere, and the pressure and temperature are similar to Earth’s surface.

Meet the backbone of Artemis III: @NASA’s 212-foot SLS core stage. On Friday, Oct. 23, crews at Kennedy Space Center used a one-of-a-kind lifting beam to move the stage out of High Bay 2 in the Vehicle Assembly Building, where it will be joined vertically with its completed solid rocket booster segments. Meanwhile, RS-25 engines for the rocket stand lined up at the L3Harris facility in Canoga Park, California. The mission will launch crew aboard Orion to test the rendezvous and docking with commercial spacecraft needed to land astronauts on the Moon. 🚀 #NASA #Artemis #Space #Moon #Science

On October 30 & 31, journey into deep space to confront a ship returned from a hell beyond imagining with "Event Horizon" as part of our Sci-Fi Supersized movie run. Get tickets here: bit.ly/4gvS3QP

🧪 What’s one science experiment you’ll never forget doing?

This November keep your eyes peeled for earthgrazers blazing across the night sky! 🌠 The Leonid meteor shower is active November 6 - 30, peaking overnight November 16 through 17, bringing fast, colorful fireballs and the occasional low-flying Earthgrazer. The first-quarter moon sets around midnight, giving dark skies for optimal viewing in the Northern Hemisphere. Find a dark spot and look up!

🔴 We’re LIVE with @MarkRober! Tune in now for a fireside chat, audience Q&A, and a live demo with Science Bob, streaming from the William and Charlotte Bloomberg Public Science Common. 🚀 youtube.com/watch?v=ujJggVXh…

⚛️ CERN has started swapping out some of the Large Hadron Collider’s most important magnets. The new superconducting ones produce fields about 40% stronger, letting particle beams be squeezed tighter.

Clearing the Air: Wildfire Smoke, Climate, and Public Health - World Forestry Center Public Panel Wildfire smoke doesn’t just stay near the flames 🔥 Join us on November 4 at 7:00pm for Clearing the Air, a panel on wildfire smoke, climate, and public health. Experts from Boston University, The Nature Conservancy, and the University of Washington will dig into why fires and smoke are getting worse, who’s most affected, and what gives them hope. ️ 🎟Free with pre-registration: bit.ly/47DJQog

🌠 What’s the coolest thing you’ve ever seen in the night sky?

Vampire bats survive entirely on blood! 🦇 Rather than sucking it out, these sanguivores nick a resting animal with razor-sharp teeth and lap up what flows. Since blood is mostly water, their digestive systems rapidly absorb the fluid while their specialized kidneys filter out the excess, meaning the bats can pee mid-meal! That clever trick keeps them light enough for the flight home.

Did you catch the Orionid meteor shower last night? Share your photos with us, or any other amazing October night sky shots! 🌠 These shooting stars are tiny bits of debris left behind by Halley’s Comet, streaking through our atmosphere at about 41 miles per second!

🌊 A study of more than 2,580 marine heatwaves at 20 U.S. estuaries found that standard measurements underestimate total heat exposure by more than 150% on average, because warm water often lingers for weeks or months around each event.
