1/7 In this stunning view you can see how the appearance of North America Nebula can change using different combinations of visible and infrared observations.⚛️ Color is used to display different parts of the spectrum.🔭🧪 www.spitzer.caltech.edu/image/ssc201... #Universe #Astronomy #Science
Yes. The window is narrow and tech is racing ahead. But surrendering early is the worst choice. Science, activism and diplomacy have protected global commons before — against far stronger economic interests. The night sky deserves the same fight. 🔭⚛️🧪 We aren't powerless. #ProtectTheNightSky
CosmicRami 🏳️🌈🏳️⚧️Nope. I don’t accept this position — that we are powerless to change the outcome of this mess. We have a small, time-critical window where we can collectively navigate through this. Also don’t forget, these are commercial entities that are selling products/services that are subject to laws.
1/6 In 2025, Gemini North data gave only a weak 1.5σ hint of a companion near Betelgeuse — a signal just strong enough to notice.🔭 The new VLT/SPHERE data raise the detection to a solid 6.1σ level (5.1σ with another method), making the result far more convincing & confirming the same location.🧪⚛️
ESOThe conclusion of a century-long quest 😲 Our VLT obtained firm evidence that Betelgeuse, a red supergiant star in the Orion constellation and one of the most famous stars in the night sky, is not alone! 🔭 🧪 1/4
Jodrell Bank is a piece of world radio #astronomy, a UNESCO World Heritage Site still leading research & training new astronomers🔭🧪⚛️ Shutting it down to save a tiny fraction of science budget is short-sighted. We can't let it become a rusting monument to discoveries never made. #SaveJodrellBank
Astronomer Royal for Scotland | Catherine HeymansI'm absolutely devastated for colleagues at Jodrell Bank who found out this morning that funding for the UK's e-MERLIN radio telescope array will be terminated. This is a short-sighted move, to save a tiny fraction of the overall UK science budget. #SaveJodrellBank 🔭🧪 www.bbc.co.uk/news/article...
Results like Joan Birman’s at 99 strike us so powerfully not only because of her age, but because they remind us that mathematical research is not a means to some external end. It is, in itself, a way of inhabiting the world with greater clarity. Read Greg Egan’s thread. #HistMath 🧪 #mathematics
Greg EganWhile the Fields Medal celebrates the under-40s, the mathematician Joan Birman has, at the age of 99, solved a major open problem in representations of the Braid groups, a topic she has worked on for more than 60 years.
1/ What’s maybe missed is that this cute corollary stage almost never comes from finding a simpler direct proof of the same statement. It usually requires the invention of an entirely new language or conceptual framework (group theory, in this case) that reorganizes a large region of math at once.
John C. BaezAnd of course key results keep getting reinterpreted as time passes, with hard results often becoming cute corollaries 50 or 100 years later. For example many important basic results in number theory became easy spinoffs of group theory (which was developed later), like Fermat's Little Theorem.
Even NASA’s Madrid Deep #Space Communications Complex, one of the world’s most important facilities for communicating with interplanetary spacecraft, is in danger.🔭 ⚛️ 🧪 Thank you to everyone working right now to save #people and structures. #SpainWildfires #NASA #DeepSpaceNetwork
