This organization is a collection point for various open source projects built by & for the astronomy community on Bluesky.

Currently, we have four active, running web projects; three of which relate to our feeds, and one of which is an outreach bot.

We maintain the Astronomy feeds, which are a set of 'custom algorithms' that collate astronomy content on Bluesky. These feeds are moderated and come from a curated list of users. Any 'astronomer' - be they professional, amateur, a student, left the field, a science communicator, etc - is welcome to sign up to post to them!

The Astronomy feeds have nearly a thousand people signed up to post to them and are seen by thousands of unique users daily. A typical week has a few hundred posts and many discussions stemming from them.

These feeds are supported by three projects:

• astronomy-feeds: a tool powered by the ATProto Python SDK that subscribes to the firehose of all Bluesky posts and adds them to a database.
• astrofeed-server: a Flask server that serves the feeds from the database to users on the app. The server's public endpoint is here.
• astrobot: a WIP bot that handles signups and moderation on the feeds.

Common code for these projects (such as to interact with our database spec) lives in astrofeed-lib.

The rules for our feeds and branding resources (i.e. the feed icon) also live in this GitHub organisation.

We are also developing a number of fun bot accounts to post interesting automated content. Currently, the running bot accounts not directly involved with the running of the feeds are:

• Galaxy-Zoo-Poster-Bot: a bot that posts images hourly that have been classified by volunteers in the Galaxy Zoo survey.
