For the last two years, I've been paying for the Astronomy feeds hosting myself. It has been a privilege to grow our community here, but I also shouldn't keep doing it for free 😅 That's why I'm delighted to announce that we now have a donations page on Open Collective! 🔭☄️ #astrophotography

🎉 The Astronomy feeds have new pinned posts! 🔭☄️ • The new pinned posts are now per-feed, so each feed has its own info & identity • There are some lovely images in the link for each feed (including one from @ltno2.bsky.social) • They include a link to a bespoke FAQ page for each feed, like this:

We're about to send lots of posts from this account, which will be the new main pinned posts for the Astronomy feeds - sorry for the spam!

We just posted a getting started guide on our website, with tips & advice on how to get started on Bluesky. Share it with a colleague or friend who might like it here! 🔭☄️ #astrophotography

Reminder for the #exoplanets feed:

Important news about the Stellar Astronomy feed: we have removed #stars as a way to post to this feed due to false positives - as with the other subtopic feeds, it's only intended for scientific posts! You can now only post to it with #stellarastronomy or #stellarastro.

Important news about the Milky Way feed #galactic: We have removed the hashtag #milkyway as a way to post to the feed, as it was causing a huge number of false positives. The hashtags for the feed are now just #galactic or #galacticastro. As a reminder, the feed is intended just for science posts!

Important news about the #exoplanets feed: We have removed the planet emoji as a way to post to the feed. Consistently, around ~50% of the posts to the feed are false positives, as 🪐 is a really common emoji. You can still post to it with #exoplanets!

📌 We have a new feed aimed at professional astronomers! 📌 The AstroSci feed is just for science posts, and you can post your smoking hot research there with the comet emoji ☄️ AstroSci crossposts back to the main Astronomy feed, and all subtopic feeds post into it too. 🔭

All done - it actually only took a few minutes! Normal service resumes on our new, shiny hosting! 🔭 #astrophotos #exoplanets #cosmology #milkyway #stars #planetsci

We're moving hosting providers for the Astronomy feeds today! Ingestion of new posts & the feeds themselves will be degraded for at least a few hours. 🔭 #astrophotos #exoplanets #cosmology #milkyway #stars #planetsci We'll post any updates in the thread below ⬇️

Well nobody here needs this post, but if you colleagues are looking to make the jump...From Lindsey Gordon @lcgordon.bsky.social : The community of astronomers on the Bluesky platform is rapidly growing, and invite you to join them. 🔭✨ astrobites.org/2025/01/21/b...

The Astronomy feeds have seen a big increase in both posts and number of authors over the past few weeks 🔭

Moderators are an important part of the Astronomy feeds community who help to keep it healthy! 🔭 We're nearly ready to appoint a new batch of mods, but would really like more applications from women & gender minorities. You do NOT need past experience to apply!

Reminder that the feeds are looking for more moderators and developers! 🔭⬇️

The Astronomy feeds are looking for more moderators! 🔭 Please consider signing up if you'd like to help sustain the health of our community here, especially while Bluesky grows. Apply below: We also could benefit from anyone willing to help with development - DM @emily.space if you'd like to!

📌 Check out all of our feeds! 📌 The Astronomy feeds network includes many different feeds covering a range of astro topics. Anyone can read them; if you're an astronomer, you can post to any of them by signing up via @bot.astronomy.blue. Here's a thread of all of them:

The Astronomy feeds now include 11 (!!!) brand new specific subfeeds! 🔭 The subfeeds try to cover every part of astronomy research with at least one feed. All subfeeds automatically crosspost to the main Astronomy feed, too! Here's a thread with links to all of them ⬇️

We're going to add more feeds to the Astronomy feeds network very soon! 🔭 Is this list missing anything? ⬇️ - Cosmology - Extragalactic - High Energy - Radio Astronomy - The Milky Way - Stellar - Solar - Exoplanets - Planetary science

Olá, Brasil! 🇧🇷 Interested in astronomy? We have an active community of astronomers posting here at the feed below ⬇️ 🔭 Astronomers can sign up to post there via @bot.astronomy.blue. You can post to it in any language - not just English!

The Astronomy feeds have three new moderators! 🔭 @celtuk.bsky.social (Chris Rolland), @kwcookastro.bsky.social (Kyle Cook), and @mpoessel.de (Markus Pössel) will be helping out with validating sign ups to the feed, making it a faster process.

The Astronomy feeds are still looking for moderators! 🔭 It won't take much of your time - helping with sign ups is the main thing, and that will only take ~5 minutes per week! The first round of moderators will be an important part of improving our community further. Sign up below:
