I'm finally done with the Elephant's Trunk Nebula after capturing 14 hours of light over 5 nights This cloud sits 2600 light years away, and is about 100 light years across. Full image, plus two crops

Measuring passing distances on 8,753 occasions in which a motorist overtook a bicyclist, Laura Hamm and Marty Miller found that “painted bicycle lanes were associated with reduced passing distance and higher passing speed.” ...

Our Director of External Affairs @tansbraun.bsky.social was on Good Morning Britain today to discuss delivery robots, which make streets hard to navigate, especially for disabled people, older people and families. Join our campaign to stop them taking over pavements. https://pavementoverload.com

These miscreants will exploit even a ten-minute gap in Transport Ministers to float their roadbuilding horrors

I met Greg at a party and bent his ear about air pollution to the extent he went home and made this AMAZING resource. This is why people shouldn't talk to meet in public

They say "The purpose of a system is what it does" in which case my purpose is endlessly to log into the microsoft programs that I'd already logged into

Unblocking cycling trips is the exactly right term. I know lots of people who would love to cycle but decide not to do so because of safety concerns. 👇

The greatest trick the devil ever pulled was convincing half the population that the "manly" way to get around is on a giant rolling couch controlled by gently depressing your toe.

Our work with @adfreecities.bsky.social, covered in the Guardian three weeks ago, showed that people are often ignorant about SUV dangers, but that giving them the facts barely changes their plans to buy one www.theguardian.com/world/2026/j... @bengoldacre.bsky.social @christianwolmar.bsky.social

SUVs are higher at the front and three times more likely to kill a child when they hit them. SUV drivers drag the child under their vehicle, and then they crush the child to death. It's incredible that SUVs don't have higher tax, and why not lower speed limits. www.theguardian.com/commentisfre...

At the turning of the millennium there were 769 satellites in space, 2026 there are 14,500 satellites. I spent 7mins photographing the Milky Way rising above Poatiri Mt Charles Hoopers Inlet, on Muaupoko (Otago Peninsula) this evening. Ōtepoti Dunedin, NZ #Photography

The number of cars on US roadways has been growing at a rate of 10 to 15 million *every year.* There are now 300 million vehicles and only 6.5% are electric. But you’ll never see an article about how the growth of vehicle emissions is “so severe it’s almost incomprehensible.”

Still very early stages, and shared as a work in progress, I've photographed a few hours of the Elephant's Trunk Nebula these past two evenings. This is about 2400 light years away, and the 'trunk' here is about 20 light years long

NEW: Eight facts about air conditioning amid an overheated global debate KEY FACT: Many European cities, on the world's fastest-warming continent, never needed AC in the past For some strange reason – I can't imagine why – many commentators prefer to ignore this

Amazing how somebody can mash their face into their keyboard and produce what almost looks like actual thoughts Not often you see an infinite ratio on here

Exactly zero effort will be made to stop this happening again

Motonormativity is putting a parking suspension for roadworks yet still putting all the roadwork signs on the pavement. @rantyhighwayman.bsky.social any idea why pavements positioning of signs seems to be the typical case?

"My car can't drive at 20 mph". FFS. Presumably you get it airlifted into car parks then?

I can only assume nobody in Microsoft has ever received an email asking "Are you free on any of these dates?", because otherwise they'd have spotted the massive flaw in Outlook that means you can't check your calendar without hiding the email

I cycled to work the longer way today. At 5.5 miles, that's further than most UK car trips - yet it took me just 22 minutes We urgently need to unblock and enable the millions of short active trips that are being blocked every day because of our collective car dependency. Our health depends on it

As an aside, I would take Haidt more seriously if he was concerned about all the technologies that have transformed childhood- often for the worse. But his vision of free play doesn't seem to engage with the technology that has had the biggest impact: cars. thedispatch.com/article/welc...

I know car parking is an inefficient use of space, but it's nothing compared to this terrible way of storing an orange

Once again, for those in the back.

This 1980s government road safety poster was designed to terrify children into vigilance when when crossing the road. It seems outdated, and yet the responsibility for road safety is still put onto pedestrians, cyclists - and children. Let's stop victim-blaming. Follow us for a better way.

Hello @crosscountryuk.bsky.social - in these temperatures do you really think it's appropriate to run a train all the way from Durham to Plymouth with no way to get anything to drink on board?

I'm at a water industry event and it's great what you overhear when you're walking around. Just now: "So were you in the bathing water just now?" between two dry and fully dressed people

This is a case study in motornormativity, car-brain, sloppy journalism and numerical illiteracy. www.bbc.co.uk/news/article... "£100m in e-bike insurance claims push up premiums for motorists". Big scary numbers, all the fault of lawless bike riders. Let's see, shall we?

I compiled a list of 350 #funding opportunities for #postdoctoral research #fellowships: https://docs.google.com/spreadsheets/d/1J2M_tQgoqV4ivpfEClh9qs9f2KQN2O1G3Jpda2aoHfQ/edit?usp=sharing I realized I should share this again after mentioning it to some folks at the #efp2026

Idea: each time we encounter criminally bad driving/parking, we save our time reporting it to the police, and instead request changes from the highway authorities and politicians? Because it might help make changes that could stop it happening in the future, while police action just… doesn’t.

You forget how far north Newcastle is. We're at least three weeks into this train journey. Spitsbergen is but a distant memory; the guard has stopped checking our tickets and is now handing out rifles and ammunition with a stern warning about polar bears

Don't say it if you don't mean it

"I care about climate change but I can't afford a heat pump/EV!" "OK, how about you cut your meat consumption?" "I can't aff... I don't want to."

Here's something I never expected: I was just over in Amsterdam visiting Marco te Brömmelstroet and, as I left, he told me the Lab of Thought have added me to their range of urbanist mugs. CAREER ACHIEVEMENT UNLOCKED thelabofthought.co/shop/p/lot-h...

If I were a health economist, it should be possible to bang out a short paper in a day estimating what the NHS savings are from increased physical activity, and thereby working out what the reward levels should be in their app

If anyone's curious, this is from an email I wrote a couple of years ago trying to dissuade a large business from doing yet another active travel reward points system

In this short talk I gave last week, I pre-emptively criticised today's new NHS "Hey, let's gamify walking!" app, arguing that if we're serious about public health we would enable change, not just encourage it

Active travel is so important for health, that the NHS is going to reward people to do it. But would it not be better for DfT and Councils to invest in pavements and cycle routes that are fit for purpose first? www.bbc.co.uk/news/article...

The fact delivery robots - despite being small motor vehicles - aren't on the roads with all the other motor vehicles is inadvertently very revealing about the dangerous state of our roads

Thread. Excellent news.

That 4% of the population who oppose or strongly oppose the use of renewable energy sure do seem to get a lot of airtime and column inches.

Map nerds have probably heard of Baarle-Hertog and its bonkers borders, but I've just been looking at the map of that area and noticed that the Holy Roman wackiness extends well outside the town. Imagine being this Dutch farmer who can't harvest his wheat without invading Belgium

Did anyone else realise Bluesky has a limit on how many mutes and blocks you can use in a day?
