The Nobel Prize committee should announce the World Cup winner tomorrow

Abolish billionaires

By 2040, ~40% of the images from Hubble Space Telescope, and more than 96% from new and future space telescopes like SPHEREx, ARRAKIHS, and Xuntian will be contaminated by internet satellite constellations. Read our new NASA article in Nature: nature.com/articles/s4158…

While "peace" negotiations continue, remember that Russia could simply stop the war at any time.

Look at this image (and thread - use the translate service). This one reads along the lines of: "..Comet C/2025 A6 (Lemmon) without cleaning. In just 15 minutes of acquisition, we counted 1,659 satellite trails (about 400 individual ones). Words cannot describe the pollution of near space." 🔭

Posts about urban biking in Dutch cities are routinely replied to with comments like “well, they have the big advantage of being relatively flat.” The Dutch also have the big advantage of not constantly making excuses about why they can’t make clearly smarter city-making decisions. #Leadership

If we invested the money wasted on "AI" into changing away from fossil fuels, this would make the world carbon neutral by about 2045. Bad autocorrect vs. a livable future. Hard choiced to be made!

one of the coolest things about ChatGPT is how you can actually just never use it. you can fill your whole entire life with simply not once using it. it's incredible.

Here's a seven-point peace plan:

We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the NIR 2MASS survey, and to a bespoke ground-based image in visible light. Here's the comparison including a tool to experiment yourself: www.euclid-ec.org/clouds-darkn... #ESA #space #science 🔭

Remember this? The most amazing thing about this remarkable 2002 car commercial is that it didn’t seem to realize at the time, or perhaps didn’t care, how effectively it made the point that cars and car infrastructure are a HUGE waste of space in cities. Award-winning 2002 ad for Saturn car company.

This!

“LLMs aren’t going away” statements are wishes, not predictions, that they’re trying to make happen. Treat them as advocacy for a specific future, not observations of inevitability

I am by no means a prominent public intellectual, but my inbox is increasingly filled with messages from people who have been convinced by sycophantic chatbots that they have discovered revolutionary theories that entirely upend our scientific understanding of the universe.

Blogpost about #ESAEuclid's Dark Cloud image, a comparison colour image in visible light, why there's such a difference (spoiler: dust!), and a video, comparison sliders, and a viewing tool to pan and zoom through the data. Tools by @ec-euclid.bsky.social #YuzhengKang, text by me. #astronomy

Do you remember the 'Dark Cloud' image of LDN 1641 from #ESAEuclid that was released by @science.esa.int two weeks ago? We now added a comparison to a ground-based image in visible light: www.youtube.com/watch?v=MlmQ... #ESA #Euclid #astronomy #space 🧵

I'm really enjoying our @astro4edu.bsky.social Shaw-IAU Workshop on Astronomy for Education online conference so far! If anyone still wants to join us, you should be able to do so from the page below. We have galaxies, best practices, working with authentic astronomical data and more! :-) 🔭🧪⚛️🎢

Microsoft warns of the AI bubble bursting. SoftBank sells NVIDIA stock. Thiel sells NVIDIA, Tesla, and other AI stock. I think it is time. They sold enough of their equity to "suckers" and now the bubble can do what bubbles do.

Learning about electric charge buildup of satellites in space by solar plasma. Interesting!

Those were beautiful #aurorae in the past days. A solar storm brought a lot of protons to Earth. Not only to Earth but also to #ESAEuclid – but does #Euclid notice? Oh yes. www.euclid-ec.org/here-comes-t... #ESA #Sun #SpaceWeather #space

If you’re media covering bike-lanes, watch this news story. If you’re a downtown business association discussing bike-lanes, watch this news story. If you’re anyone hearing the LIE that bike-lanes are bad for business, watch this story. And please SHARE THIS STORY so others can watch it too.

This is a good article, worth reading. Gigantic SUVs are a public health threat. Why don’t we treat them like one? The anti-smoking playbook is worth studying and learning from, and is completely applicable to oversized cars. Via @davidzipper.bsky.social in @vox.com #CarBloat

"World's first potential trillionaire has killed 600,000 people, including 400,000 children" is the only headline that anyone should ever read about Elon Musk

One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

Euclid and the Dark Cloud I haven't posted anything recently about the European Space Agency's Euclid mission, but I can remedy that by passing on a new image with text from the accompanying press release. This is actually just one of a batch of new science results emerging from the first `Quick…

Commute to work today: #Heidelberg #cycling

Here's a cutout, this is about 1% of the full image. Young stars, dust and gas being blown out, a lot is going on. The #ESA page has in-depth explanations. #stars #starformation #astronomy 6/

The second image released today is by the EC and @esa.int, of the 'Dark Cloud' LDN 1641 – a near-infrared colour view through thick dust by #Euclid's NISP instrument: www.esa.int/ESA_Multimed... #space #astronomy 4/

We are releasing seven new science publications today, based on our Q1 data release earlier this year. All revolve around galaxies, from dust to interactions to active centers.These are accompanied by two new image collages drawn from the same release. 1/ 🔭 #astronomy #space #ESA

TIL that Zohran #Mamdami convinced his mother not to take the offer to direct 'Harry Potter and the Order of the Phoenix'. Oh and she has won a Golden Lion at the Venice film festival, and has BAFTA, Golden Globe, and Oscar nominations for her work. en.wikipedia.org/wiki/Mira_Nair

@astroroyalscot.bsky.social Sarah Hörst blocked me just now. Can you fathom what in my reply enraged her so much to do this?

A US tech startup is proposing to use mirrors in space to power solar farms on Earth at night. Is this even feasible? And what are the light pollution dangers? Myself and @mattkenworthy.bsky.social have crunched the numbers for The Conversation. theconversation.com/a-us-startup...

I'd give the prize to Greta Thunberg just to see the look on Trump's face

The Galaxy & Cosmology Dept at @mpi-astro.bsky.social has opened a call for its 4-year prize fellowship and up to 11 postdoc positions. We have an AAS ad as well as a page with a more detailed description of the positions and groups: www2.mpia-hd.mpg.de/~gc_jobad/gc... aas.org/jobregister/... 🔭

Das Problem dabei ist aber, dass Anlagen, die sich allein durch Eigenverbrauch rechnen sollen, deutlich kleiner ausfallen und die Dächer dadurch nur zum Teil belegt werden.

No Avi, that Perseverance Navcam picture you posted isn't showing 3I/Atlas, it's just Phobos, the brighter one of Mars' moons. If you were even half the expert you think you are, this possibility should have been quite obvious and worth mentioning.

This is complete and utter pompous bullshit. It's telling that of the people proposing it wants to anoint themselves director general when every one of his claims of having discovered technosignature interstellar objects has been debunked by the planetary community. arxiv.org/pdf/2510.01405

This tweet has been doing the rounds on Twitter now that Nathan Gill has pleaded guilty. If only someone had tried to investigate UKIP & Russian interference 🧐 There’s another timeline where the Guardian supported me, doubled down on the investigation & I look 5 years younger ..

"She was an extraordinary personality, who did not let convention intimidate her": Nadine Neumayer, head of the Lise Meitner Research Group 'Galactic Nuclei' @mpi-astro.bsky.social, on the inspiring #DarkMatter pioneer #VeraRubin, who transformed our understanding of the universe.🌟🌌

Das ist krass: Julia Klöckner lässt jetzt einfach abstreiten, dass sie die taz und Nius verglichen hat - mit Verweis auf das schriftliche Redemanuskript. Dabei war @larswienand.bsky.social vor Ort und hat einen Mitschnitt der tatsächlichen Rede. kress.de/news/beitrag...

Manche Leute reagieren mit Abscheu auf die autoritären Moves, die Trump in den USA derzeit vorführt. Andere offenbar mit „Hm, stimmt, sowas in die Richtung könnten wir tatsächlich jetzt auch mal machen.“

"Niemand fällt bei uns in die Armut, nur weil er arbeitslos ist." Das hat er wirklich ernsthaft gesagt. Ich wünsche Multimillionär und Bundeskanzler Merz mal drei Monate lang ein Leben von Bürgergeld.

Make no mistake, everything that’s happening in the United States is being significantly enabled by the right wing oligarch capture of media. Every other country needs to do everything possible to keep that from happening where they are. Including protecting the CBC from Poilievre here in Canada.

Faschismus. Die öffentliche Sphäre wird gesäubert. Social Media kommt als Nächstes.

Ich hoffe sehr, dass sich das ZDF robust hinter Theveßen stellt und nicht der massiven Schmutz- und Desinformationskampagne nachgibt, die gerade gegen ihn und jeden gefahren wird, der nur Kirks eigene Worte wiederholt. Meinungsfreiheit gilt bei MAGA nur für die eigenen Leute- nicht für den Rest.

This is incredible!

1/ A rising telescope under a rising Sun and Moon! 🔭☀️🌕 This montage is a kaleidoscope of moments from the construction of our Extremely Large Telescope. Creating this #ELT collage took Boris Häußler, an ESO astronomer in Chile, years of meticulous planning.
