For over a decade, mathematicians have failed to agree whether a 500-page proof is actually correct. Now, translating the proof into a computer-readable form may finally settle the matter

Grace Chan, author of Every Version of You, the November read for the New Scientist Book Club, explores the philosophical implications of the choices her characters make

Flamingos aren’t born pink 🦩 They start out gray or white, but pigments in the algae and shrimp they eat build up in their bodies over time. Those carotenoids color their feathers, skin, and beaks that famous shade of pink. You could say their diet paints them. 💕

In honor of Carl Sagan's birthday this past weekend, here are some related books that will be available later this month for purchase to support @astrosociety.org... 🧪📚🔭

Happy Birthday, @carlsagandotcom.bsky.social.

HBD!

Today we’re leaving the #MilkyWay behind and heading into the Large Magellanic Cloud. Our destination? A binary system that seems like a lone blue star, but actually also hosts an invisible black hole, weighing at least 9 times the mass of our Sun. More: https://www.eso.org/public/news/eso2210/ 🔭

It’s like the GameCube grew up, hit the gym, got a Steam account, and now won’t shut up about frame rates and ray tracing.

Mindfuck is an understatement… it’s a console that’s actually a PC, made by Steam—the PC game store. So now you need a console to play PC games on your TV that came from your PC library. It’s like Steam looked in the mirror and said, "what if I was the mirror?" My brain just crashed and restarted.

This is Goose. His stick didn't fit through the door at first. But Goose believed in himself, and more importantly, so did his doorman. 13/10 (TT: bigstickgoose)

The devious trick behind the most sensational science headlines Sick of sensationalistic science headlines that promise revolutions, but that don't pan out? Here's what's wrong with science news, and why you keep seeing those dubious stories. bigthink.com/starts-with-... #space #physics #news

The Super Mario Galaxy Movie's fantastic first trailer introduces Brie Larson's Princess Rosalina and Benny Safdie's Bowser Jr.

🎆📯 Northern Lights klaxon 📯🎆 Yes that's right, tonight offers another chance to catch a glimpse of the beautiful aurora borealis. It looks like the strongest aurora will happen before midnight – but it'll depend on where you are in the UK and if you have clear skies. ☁️ Good luck!

This is perfect for Mario + space lovers! I’ve been dreaming for more than 25 years about a Mario-in-space thing—way before the actual game even existed. And now, there’s a movie! Talk about the universe finally answering my childhood fanfiction like, "Fine, kid, here you go." ✨

📣 For the first time ever, scientists have confirmed seeing a giant explosion on a star other than our own! Our XMM-Newton observatory and the LOFAR telescope contributed to making this long sought-after discovery 👉 www.esa.int/Science_Expl... 🔭 🧪 ☄️ ☀️ 1/

⚡️Solar storm incoming! We are actively monitoring severe space weather events, occurring on 11-12 November. Severely disturbed geomagnetic conditions are expected to persist for at least 24 to 48 hours. 🔗 www.esa.int/Space_Safety... @operations.esa.int @science.esa.int

Cette nuit, nous avons vécu un évènement EXCEPTIONNEL!! Des aurores boréales en France métropolitaine. Ça pourrait se reproduire encore ce soir. C'est dû à quoi? Thread!👇

They are literally standing on the world's best solar generator and opting for the smoke-stack. It's the most expensive, convoluted way imaginable to capture energy. The Sun is free, but the profit from gas is apparently too valuable to ignore.

The Northern Lights were visible across the country last night, with red and green hues illuminating the night sky

Five thousand light-years away lies the magnificent Lagoon Nebula — an interstellar cloud stretching over 100 light-years across. It boasts many large, hot stars, whose ultraviolet radiation sculpts the gas and dust into unusual shapes. www.eso.org/public/image... 🔭 #Flashback

Aurora Science 🔭🧪 What do the colors of the aurora tell you 👇

I really need to get to bed, but I just poked my head out the back door again. This is the view from my deck. All of this is looking south. When the geomagnetic storms are like this, the oval overshoots me and stretches into the US, which is why so many are seeing it tonight. #aurora

*1.4 million displaced. One of the strongest storms the country’s seen in years. I ache for the poorest—those with nowhere to run, their cardboard homes and fragile hopes washed away overnight. Nature doesn’t choose its victims, but poverty makes sure the same souls suffer most.

1/ Milestone achieved by the VLTI upgrade GRAVITY+: a laser has been installed at each of the previously unequipped VLT Unit Telescopes. This will dramatically enhance the VLTI observing power. Discover more with #ChasingStarlight: https://www.youtube.com/watch?v=TzK1B3VU1L8 🔭 🧪

While the Magellanic Clouds shine upon the Chilean Desert, two VLTI Auxiliary Telescopes point up to the sky — all together reminding us of how small we are as humans compared to cosmic objects & the telescopes we observe them with. https://www.eso.org/public/images/potw2545a/ 🔭 🧪 📷 J. Looten/ESO

Tomorrow at 16:30 CEST at the Heidelberg Joint Astronomical Colloquium, Dominik Schleicher will discuss the implications of N-body simulations with stellar evolution for Little Red Dots, a new population of very compact red galaxies discovered by JWST 🔭 physik.uni-heidelberg.de/hephysto/ind...

Since its installation on the ISS in 2011, the AMS has recorded over 200 billion cosmic ray events. #FunFact: the AMS has been on the ISS for over 5,280 days and counting. Find out more: home.cern/science/expe...

Here we see the Alpha Magnetic Spectrometer (AMS) detector. Most recently upgraded in 2024, it searches for dark-matter signatures from cosmic rays, #antimatter, and missing matter from its position on the exterior of the International Space Station.
