Hello HN! Sharing a recent side project of mine, the Atlas of Space, that I built out to explore the Solar System. As a long-time space nerd, I realized recently that I didn't have a good intuition on the scale, speed, and relative orientation of the celestial bodies around us. So over the break I built out a kind of spatial Wikipedia to click around and learn about planets, moons, asteroids, and other bodies orbiting the Sun. The physics is all simulated in the browser using simple Newtonian mechanics. There's a lot left to do from here, including modeling objects in non-Keplerian orbits…

I really like Stellarium and SkySafari but I felt like these are primarily geared towards exploring the sky but not so much "here are the long list of things I want to see, when can I see them tonight and where". There's also not really a great option I've found that combines sky object planning + location weather details while still being free so I built this. The UI's heavily inspired by NINAs sky atlas + Robinhood. Right now you can: View the altitude chart of objects and 3D view Create lists of objects of interest View the annual max/min daily altitude of an object to find the best…

I made this site using R3F (https://github.com/pmndrs/react-three-fiber), a React renderer for 3JS (https://threejs.org/). The celestial bodies are Three.JS meshes. I used loaders (namely 'useLoader' from R3F and 'GLTFLoader' from 3JS) to import 3D models, such as International Space Station. More on loading models in R3F: https://docs.pmnd.rs/react-three-fiber/tutorials/loading-mod... I've future plans for this side project. It would be great to hear from the HN community before diving into them. Enjoy! P.S: Getting an empty…

Hello, I am the creator and maintainer of Stellarium Mobile. I have been working in my free time for about a year on this new project Galaxium, that is more about traveling in the universe rather than looking at the sky from Earth. It is still experimental, and at the moment I am not sure what it will become. Feedback is welcome.

I made a single-serving iPhone app with a floating green arrow that always points to the center of the Milky Way, 26,000 lights years away. It’s weirdly grounding. I’ve never made an app before, so here’s how it worked with ChatGPT.
