    When I was a kid I used to play a bit with Celestia, but I remember I was pretty scared whilst using it... there was some kind of dread/anxiety I felt just looking at the vast void of space and something giant like Jupiter or Saturn next to it, I always thought an UFO or something was gonna pop out of nowhere.

    I don't know if this feeling is common or not but I do remember reading about someone here on on Reddit feeling a similar thing, I believe it to be similar to thalassophobia.

      Same! I lost days looking for the most distant galaxies and traveling to them. I always felt the same anxiety of the emptiness thinking why the universe doesn't give us a way to explore it, why I was born so early or in a _lame low tech planet_ (in a lame low tech country) or how incredibly diverse could be the life out there. I remember being fascinated by the sheer number of galaxies and then "wait, this app doesn't even zoom _into_ galaxies", which is another level of infinityness, and that was just overwhelming. Man, I feel depressed now.

    Decades ago, I patched Celestia to add a Star Trek–style warp speed selector, only to realize that even at maximum warp, I was still crawling along like a snail. At least it was a fun hack.

    Great project! Been using it for years together with VTS [1] to visualize real-time and propagated satellite positions and attitudes, and also star tracker and payload "beams".

    Is there an option to increase the font size? The text is unreadably small on my 28" 4k display.

    Hidden well enough on the linked site, but easy to find in search; there are mobile versions which work well on tablets etc I just found out. That's this monday lost!

    One thing I kind of always want to see when I find cool resources like this are "How are you funded?". Because if it's not clear then have to there's a high risk it's a rug-pull, virus or might one day be either. There's just too many secretive "Here's a super free perfect tool for you!" rug-pulls out there.

    "We're funded by the goodness of a team of volunteers" is a great answer.

      Are you new to the concept of open source?

      Celestia had been operating for years. I was using it 20 years ago.

    Now somebody gotta do it as a mod for KSP, it would be sick to have this level of detail and launch missions through the solar system.

    Yes, I know Real Solar System is a thing, but still :D

    This website does not work with Oculus Quest browser, it goes to the "oh noes" page, i guess the meta browser has some issues with the bot detection algorithm.

      Brave also exhibits this behavior, turning off shields fixes the issue.
