Galaxy site directory
Every topic on galaxies.im will get its own site. Black holes and the Milky Way come first. Here’s the plan for the first ten.
Open now
This hub, galaxies.im. The galaxy sites below will be listed as open, with a link, on the day each one goes live.
Coming soon
- Black holesFirst wave
black-holes.galaxies.imPlanned: what a black hole is, the event horizon, and Sagittarius A* at the heart of the Milky Way.
Coming soon - The Milky WayFirst wave
milky-way.galaxies.imPlanned: our home galaxy, its spiral arms, where the Sun sits, and how to see the Milky Way for yourself.
Coming soon - The Big Bang
big-bang.galaxies.imPlanned: how the universe began, its first seconds and minutes, and the evidence astronomers use.
Coming soon - Andromeda
andromeda.galaxies.imPlanned: our nearest major galactic neighbour, how to spot it, and how Edwin Hubble showed it is a galaxy of its own.
Coming soon - Dark matter
dark-matter.galaxies.imPlanned: the invisible matter that holds galaxies together, and the work of Fritz Zwicky and Vera Rubin.
Coming soon - Space telescopes
telescopes.galaxies.imPlanned: Hubble, Webb and the space telescopes that photograph distant galaxies.
Coming soon - Quasars
quasars.galaxies.imPlanned: the brightest objects in the universe, powered by giant black holes, and 3C 273.
Coming soon - Supernovae
supernovae.galaxies.imPlanned: exploding stars, how often they happen, and the remnants they leave behind.
Coming soon - Nebulae
nebulae.galaxies.imPlanned: clouds of gas and dust, stellar nurseries and planetary nebulae.
Coming soon - Magellanic Clouds
magellanic-clouds.galaxies.imPlanned: the Milky Way’s two satellite galaxies in the southern sky, and how they got their name.

How we chose the ten
We ranked well-known topics beyond the solar system by how many people read about them online over a year, then left out the planets and moons, which have their own hub. Black holes came out top, so they come first, with the Milky Way alongside.
Independent, not official
Our facts come from NASA and Encyclopaedia Britannica. galaxies.im is not affiliated with, or endorsed by, either of them.
How the network works
The list of sites lives in network.json. This page and sitemap-index.xml are built from it, and only open sites go into the sitemap index. Each galaxy site will have a link back here at the top of every page.
