New instance, new #introduction !
Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.
One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy
And many thanks to @sebinthestars for running our former instance!

Look forward to what you'll share here!
Perhaps you know this already, but if not then, Mastodon has the ability for accounts to verify who they are by way of their domains (in your case esa.org). Think of this as Mastodon's version of the blue checkmark from other platforms.
It is easy to set up, and would signal to everyone that your account is in fact the official ESA account.

"A cyclist is a disaster for the country's economy: he does not buy cars and does not borrow money to buy. He does not pay for insurance policies. He does not buy fuel, does not pay for the necessary maintenance and repairs. He does not use paid parking. He does not cause serious accidents. He does not require multi-lane highways. He does not get fat.
Healthy people are neither needed nor useful for the economy. They don't buy medicine. They do not go to hospitals or doctors. Nothing is added to the country's GDP (gross domestic product).
On the contrary, every new McDonald's restaurant creates at least 30 jobs: 10 cardiologists, 10 dentists, 10 dietary experts and nutritionists, and obviously, people who work at the restaurant itself."
Choose carefully: cyclist or McDonald's? It is worth considering.
P.S. Walking is even worse. Pedestrians don't even buy bicycles.
P.P.S. If you have read this far and still don't get it, this post is SATIRE. Reread it with this in mind.

@jackofalltrades @stekopf We are taking marginal costs here. The overwhelming share of digital goods footprint is at the hardware fabrication and disposal stages.
@MathieuP @stekopf
Not only that. Energy is also a very important input, which comes back nicely to the gasoline for a car vs digital subscription example.
It's hard to avoid news like these nowadays:
cnbc.com/2025/06/21/why-electr…
or:
npr.org/2024/09/20/nx-s1-51205…
Or even a cursory browse of @gerrymcgovern feed will give you a good idea of how much input the digital world requires.

@MathieuP @stekopf @gerrymcgovern
While it is obvious that more energy is needed to move a car than to stream an album over the internet, it becomes much less obvious once the whole system is taken into account. Just like roads have costs, so does the internet infrastructure. Storing and streaming data requires data centers, routers, switches and cables that not only need to be constantly powered, but also periodically replaced.
1/2
@MathieuP @stekopf @gerrymcgovern
In fact, diesel-powered trucks visit data centers every day to replace old and broken equipment.
Given all that, can we be sure that $100 of digital goods requires smaller resource input than $100 of gasoline?
Our world becomes increasingly digitized and yet our resource use is only going up. How would you explain that?

Firstly, because I have recent lifecycle analysis under my eyes. We are talking differences by one or two orders of magnitude, there.
Secondly, the increase of resources consumption at world level is overwhelmingly the effect of development. In the Western world, resource consumption per capita is stable or decreasing in most countries (the US are, as for health, the embarrassing outlier).

Could you share a link to that research?
"In the Western world, resource consumption per capita is stable or decreasing in most countries."
That is surprising. Is this accounting for trade?

@MathieuP @stekopf @gerrymcgovern
This is energy only, and the claim was about all inputs.
It may be hard to find good estimates from the production side, so we may as well look at the waste side:
ourworldindata.org/grapher/pla…
Europe went from 2.11m tonnes of plastic waste ending up in the ocean in 2000 to 5.05m tonnes in 2019.
Similarly, according to:
globalewaste.org/statistics/co…
Europe went from 15.6kg of e-waste per capita in 2015 to 17.6kg in 2022.
@MathieuP @stekopf @gerrymcgovern
I live in Europe and wherever I look I see more *stuff*. There's no way we are using less resource inputs per capita than 20 or even 10 years ago.
@jackofalltrades @stekopf @gerrymcgovern I think we have little grasp of how inefficient cars were when we were young (I live in France).
A current BMW consumes half as much as a 1990's Ford Sierra.
There has also been bounds in energy efficiency of most home appliances and heating devices.
You'll also notice that there is more stuff, but most of it is so much lighter than it used to be.

Yes, but there were less cars when I was young. The playground next to my parents' house has been converted into a parking lot. 🙁
The car sizes also changed drastically. Our family of five drove on vacation in Fiat 126p. Now my two parents drive alone in Toyota RAV4.
The lighter stuff may still have a bigger environmental impact / material input. Just ask yourself: how many kilograms of raw materials must be mined to produce a single cell phone?
@jackofalltrades
A single cell phone? Last time I checked up, it was about 60 - 90 kg of mining waste for that 140 grams of specialness. And about 14,000 liters of water. Not to worry, we've only made and dumped about 16 billion of them since 2007.
@jackofalltrades
Excellent points. Bigger and worse. Lighter and more throwaway. Planned obsolescence and all that. Driven by the corrupted concepts of innovation and efficiency.
There's more materials in a modern tire than there used to be in an entire car. What that means is that tires are toxic time bombs, with a car’s four tires generating one trillion toxic nano particles of dust for every kilometer driven. But, heh, innovation and efficiency!
@gerrymcgovern @jackofalltrades @MathieuP @stekopf yeah, the average car is also a LOT heavier, as well as bigger (and electric vehicles are the worst, as they are both heavier and don't become lighter as the fuel is used up) causing more damage to roads, which have to then be repaired. And they even take up more space when parked...

@MathieuP @stekopf @gerrymcgovern
No, I'm arguing that deriving a marginal cost for digital goods is not as straightforward as one could wish. Unless we externalise pretty much everything, which would make your original point about "less inputs" moot.
@MathieuP @stekopf @gerrymcgovern
To give an example of what I mean:
If 10 more subscribers to Amazon Prime causes Amazon to run an additional server, is that part of their fixed cost or marginal cost of the new subscriptions?
If 10 more people are streaming movies every day causing the ISP to upgrade their routers is that part of their fixed cost or marginal cost of the new subscribers?
Etc.

Prior to getting my Masters and PhD in Nuclear Engineering at Berkeley I was a nuclear trained officer on a submarine. After graduating I worked in reactor core design at a nuclear company. I now work as a nuclear physicist at a national lab.
I just wanted to establish my bona fides before assuring you that yes, your assumption is correct that bombing any kind of nuclear infrastructure is dangerous and reckless as fuck.

We've had experience mixing radioactives and high explosives for almost exactly 80 years now and in all that time we have not solved the problems of atmospheric dispersion, aerosol transport, inhalation and submersion dose. We quibble over details but the fundamentals remain - if you do not want radioactive material all over, you should not blow it up.
I've been working on this problem professionally on and off for 30 years on the civil nuclear side; power plants, legacy defense waste. Your assessment is spot on - bombing nuclear facilities is reckless, dangerous, and egregiously irresponsible. There's no other way to spin it. (diagram from osti.gov/biblio/4743102)

I remember Andries Meijerinck from Utrecht telling the story of how he had a visit from some people from the European Central bank who wanted to learn about luminescence. He spent a few hours talking to them and then didn't hear from them. When the euro banknotes appeared he recorded the spectra of the inks - sure enough they were a mix of Eu(III) and Eu(II)…
And I think they're in other banknotes, including pounds, though I've never got round to recording the spectra. 1/2
And I think they're in other banknotes, including pounds, though I've never got round to recording the spectra. 1/2
When I was interviewed for my EPSRC SMF I showed the luminescence of euros with a black light, an then managed to get Robert Winston to pull a £20 note out of his wallet to show the inks on the notes. I pointed out the luminescence and suggested that perhaps Gordon Brown had a stealth plan to bring the pound closer to the euro. I got a laugh for that, but got an even bigger one when I "carelessly" slipped the note in my pocket.
To my astonishment, I got the fellowship. 😜

@sellathechemist haha, brilliant :)
Recording banknote spectra would be an interesting task... just to identify the list of elements included. With a sweepstake beforehand to guess the number.
