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!

@esoastronomy Welcome, again!

You weren't able to migrate your followers to the new instance? I've never moved myself but I was under the impression that while you can't take your old posts with you, you could take your follows and followers.

@spacelizard Hi Anthony! They show up on our end: 3.4k followers, very close to what we had in astrodon, probably a few remain to be moved. Maybe this information takes a bit to be replicated in other servers.
@esoastronomy welcome. On my end it appears you have 1.2k followers. Out of curiosity what was the rationale for switching to one of the most crowded instances?

@WuMing2 I am also curious, as we have many scientific instances.

@esoastronomy

@NatureMC I can answer that. Astrodon is shutting down: https://astrodon.social/@sebinthestars/114595973387772639

After two and a half years of building this community, I've made the decision that it's time to shut down Astrodon.social. Since 2022, around 4,000 users have registered on astrodon.social. However, fewer than 10% of those users are active each month, and fewer than 1% post regularly. Because of the way Mastodon works, the data for every one of the those users, even the inactive ones, has to be kept forever and keeps on growing. There's no way to remove posts or archive them out of the database, and running a large database gets very expensive. Running Astrodon costs more than €300/month, which means that the costs of running the server are primarily going toward servicing fewer than 50 active users, the most active of whom are organisations. Even with donations, Astrodon has now cost me more than €5000 to run. While I’ve considered the option of turning Astrodon into a commercial service or creating a nonprofit, I’m reluctant to go down that route. Managing a business comes with a host of overhead tasks like tax reporting and navigating different tax regimes due to our global user base, which is something I want to avoid. My goal has always been to create a free and open space, but the reality is that the free part isn't sustainable. I'm not shutting down Astrodon immediately. I want to give everyone ample time—likely over the next two to three months—to find alternative service providers and transition smoothly. This isn't a decision I'm making lightly, and I appreciate your understanding and support as we navigate this transition. If you have any questions, concerns, or suggestions, please feel free to reach out to me directly through DMs.

@WuMing2 Thank you!
@NatureMC @WuMing2 Indeed, and Seb has done a fantastic job running that instance!
