Why is so little of the universe antimatter? We don't know. Scientists keep looking for ANY differences (besides the obvious) between matter and antimatter, but keep coming up empty. A new experiment… again shows no difference. It's weird. badastronomy.beehiiv.com/p/psyche-s-m... 🔭 🧪

Psyche’s Mars, and another test to see why antimatter is different than matter

Very cool animations of Mars as the spacecraft flew by. Plus, antimatter is still baffling.

New from James: how fire danger is changing across Europe 🧪

James Dinneen@jamesdinneen.bsky.social · 6d ago

Fire suppression in Europe has led to an overall decline in wildfire since the 80s, despite a global warming-fueled rise in risky fire weather. That can't last. "This is the kind of trend that is unstoppable." New in @nature.com:🧪 www.nature.com/articles/d41...

From the abstract: “promoting a woman to Associate Professor increases female faculty by 1.5 members after 15 years, leads to six additional female PhD graduates over the following decade, and raises the number who subsequently remain in academia and reach tenured positions”

Sadly it's not just #JodrellBank losing funding, with deep cuts across the board for UK astronomy. One example is the HiPERCAM project whose funding has been entirely cut to save £50K/yr - peanut-levels of £s. Spectacular fast transient science lost, for what? 🔭😡 www.zmescience.com/science/astr...

"Two studies published in 2024 robustly predicted that in December that year, the companion would be furthest from Betelgeuse and hence easier to spot." Nice to see that our Betelbuddy prediction was spot on. :D www.eso.org/public/news/...

Private companies could ruin the night sky for the entire world, and international law can't stop them

The U.S. Federal Communications Commission (FCC) can single-handedly approve space projects that will change the night sky around the world. The international community can do very little against it.

To be clear- this is catastrophic for radio astronomy, not just in the UK. If you shut down a facility like this not only do we use access to the facility, dozens (hundreds?) of jobs are gone and with it expertise that never comes back. Please write to your MP if you’re in the UK! 🔭🧪🎢

Chris Lintott @chrislintott.bsky.social · last wk.

Short-sighted, stupid cuts to the UKRI budget include shutting down Jodrell Bank, the icon of British astronomy. (Many other cuts too, including 20% to our brand new @vrubinobs.bsky.social). Interesting politically to shut down a major facility in...um..Manchester 🔭 www.bbc.co.uk/news/article...
