  • Show HN: The Atlas of Space
    Incredible work! My son really had a blast scrolling around and exploring last night. Did you take any inspiration from Celestia (https://celestiaproject.space)? It's been over 15 years since I last really used it (and starts with defaults not geared towards visualizing just our local solar system) but seems to have a lot of the features others have suggested. Might be useful to poke around and see how they solved... - Source: Hacker News / over 1 year ago

    Pretty much everything beyond our solar system is essentially fixed on a human timescale. Over 2000 years, a typical star will move about half a degree. That's the width of the moon in the sky. There are of course notable exceptions like Barnard's Star, whose movement is pretty obvious on photographs taken over several decades. If you want to explore how space changes over time, I recommend you look into... - Source: Hacker News / about 2 years ago
  • My 9 year old nephews drawing of stars
    I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: over 3 years ago

    If you're hell-bent on headless, I can personally recommend 11ty (https://www.11ty.dev/) and hugo (https://gohugo.io/). That said, for non-technical admins, you probably want a user interface. For that, Ghost (https://ghost.org/) and Grav (https://getgrav.org/). Or Wordpress! - Source: Hacker News / 11 months ago
