The Orion Cold Snap
Ever wonder why Antarctica got its icy makeover 14 million years ago? Blame it on a galactic road trip! 🌌 Scientists think our solar system passed through the Orion star-forming complex, compressing our heliosphere (our cosmic bubble) and dumping extra interstellar dust onto Earth. The result? The Middle Miocene Climate Transition—aka, Antarctica got really, really chilly. Thanks, Milky Way! ❄️ (Read more)
NASA’s Trailblazer: A Tiny Dishwasher with a Big Job
NASA’s Lunar Trailblazer is small but mighty—about the size of a dishwasher, this spacecraft is heading to the Moon to track water. 🚀 It’s part of NASA’s SIMPLEx program, which aims for big science on a budget. The goal? Find and map lunar ice so future astronauts don’t have to BYO water. Slow? Yes. Useful? Absolutely. (Source)
Australia Launches a Rocket… and Vegemite?!
For the first time ever, an Aussie-built rocket is trying to reach orbit from Australian soil. But that’s not the weirdest part—the 25-meter-tall Eris rocket will be carrying a jar of Vegemite.

Want to Call ET? Forget 911, Try 21 cm
If you’re looking to phone home from deep space, forget cell service—try the 21 cm hydrogen spin-flip signal. 📡 Hydrogen, the most abundant element, occasionally flips its electron spin, releasing a signal so universal it’s basically the Rosetta Stone of alien languages. Any smart extraterrestrials should recognize it. (Read more) Bonus? Scientists also use this wavelength to map the Milky Way! (Read more)
Finding Rogue Planets—The Universe’s Lost Luggage
Think rogue planets are just kicked-out misfits? Think again! New research shows that free-floating planetary-mass objects (PMOs) might form in young star clusters rather than being exiled by their parent stars. So, somewhere out there, lonely planets are drifting through space, waiting to be found. Maybe one of them is looking for a home? 🌍👀 (Read more)
