This reminds me of something important.

The widespread availability of colour balanced digital images of nearby galaxies is so very very useful.

Because β€œlooking at images, not catalogs” is a dying pastime, the paper includes a tutorial on -how- to interpret images of galaxies. Qualitative information alone can get you a surprisingly long way towards a reasonable model, if you’re thinking through the links between morphology and physics.

The Discourse has become sort of numb to the fact that the richest guy on earth and owner of a major social media platform just routinely spits out the kind of nakedly white supremacist shit that until a decade ago you rarely saw outside of places like Stormfront.

Yesterday, in a cab here in Paris, we were sitting in traffic.

Driver started becoming very excited and pointed towards something in the sky.

We all looked up, and it was a very bright fireball, entering the atmosphere and moving relatively slowly.

~18:50, North East direction, ~ 30-deg elevation

ESA analysing fireball over Europe on 8 March 2026 At approximately 18:55 CET (17:55 UTC) on Sunday 8 March 2026, a very bright fireball moving from the southwest to the northeast was observed by many people in Belgium, France, Germany, Luxembourg, an...

πŸ” What we know so far

Fragments are reported to have reached the ground in Koblenz‑GΓΌls (Germany). There are no injuries reported.
Due to its timing and direction, the object was likely not detectable by current large-scale sky surveys.

One gets the impression the DOGE dudes and their ilk were the students who never studied and tried to copy or cheat on assessments.

My pet theory is they used β€œDEI” as cover for their gross failings and to get ahead in reactionary circles.

Saw an odd flash near Achernar at 9:10pm this evening - while I’d hope it’s something astronomical I suspect a curious short satellite flare is vastly more likely.

Dozens killed as Israeli special forces raid Lebanese village in search of 40-year-old remains Overnight, one Israeli operation saw at least 41 people killed and 40 injured, according to the Lebanese health ministry.

Pretty serious allegation here. "Witnesses told the BBC that the Israeli soldiers had arrived disguised in Lebanese military fatigues and used ambulances with signs of Hezbollah's Islamic Health Organization."

The naive use of ChatGPT is getting attention but career senior staff just rolling over is another aspect.

An excellent explanation of why a million data centres in space is a terrible idea and probably cannot work. The number of launches and reentries each day is absurd and the pollution vast.

This research group’s key metrics are publicity and retractions.

A few years back I found one of their papers had a photograph with a bogus north label - the shadows were all wrong.

Chart showing in many countries, people see their fellow citizens as morally good.

We asked people around the world to rate the morality and ethics of others in their country.

The U.S. is the only place we surveyed where more adults describe the morality and ethics of others living in the country as bad than good. See our full morality report here: www.pewresearch.org/...

The Albanese Government's case for crackdown on FOI fell apart when it became clear that there is no "flood" of FOI requests.

Case load is about the same as 20 years ago. The extra costs and delays are a result of FOI officers spending their time trying to block access and censor documents.

Most painted bike lanes are so narrow that they become useless when cars park in them as the entire lane is in the β€œcar door zone.”

Wider lanes are ok but occasionally one gets cars using them to undertake slow/stopped traffic.
