Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…

Hi HN, I'm a solo dev working on a space RTS game set in the Milky Way galaxy, containing currently known stars and exoplanets with their real characteristics, the remaining stars are procedurally generated. In the online mode, all players are in the same universe, and the world is persistent. You compete with other players to take back the Solar System and end your exile. Players can always retreat to the periphery to regain strength and rebuild their fleets as needed. It also includes an procedural spaceship generator that allows creating your own spaceship designs. Spaceships visuals…

This was my recent weekend project, aimed at teaching me JavaScript, a bit of HTML5, and (mostly) WebGL. The orbital data are from NASA JPL. I was inspired in part by this Flash app: http://www.dynamicdiagrams.com/wp-content/uploads/2011/04/orrery_2011_bce.swf, but wanted to do something in 3D. Coming from the games-dev world, this is my first introduction to web coding. The UI is jquery. I mostly used http://learningwebgl.com/blog for the 3D stuff. Being WebGL, it will work mostly on Chrome, Firefox 4 Beta. Forget about IE. I needed to figure out how to render text to the WebGL canvas - I…

Hi there, humans! I'm a big fan of any topic related to our universe. I'm also a developer, so I've put these things together and I built this new tab Chrome Extension for space lovers, astronomy fans, and science geeks like me. If you enjoyed it, please spread some love <3

I’ve spent the last few days prototyping a browser-based game engine stack designed for instant-load, "Roblox-for-Teens" style deployment. The goal is to lower the floor for AA indie devs who want high-fidelity physics and instant web distribution without the overhead of Unity or a heavy Godot export. The Stack Engine: A headless WASM/WebGPU implementation. I’m currently using custom flags and selective streaming to bypass standard browser memory and execution limits. Physics: I’ve ported Jolt (Guerrilla Games) but modified the solver to mimic the original Blam! engine (Bungie/Halo…

Hi HN! I’ve spent the summer of the past 2 years building The Atlas, a procedural universe simulator that generates 1 sextillion galaxies (10²¹) from a single mathematical seed. Think No Man’s Sky meets theoretical physics, but running entirely in your browser. Everything is purely deterministic, the universe is calculated from SHA-256 hashed seeds using the golden ratio as primordial constant. There’s no database, no pre-saved data, just pure math. Time itself is treated as a coordinate, so the universe exists as a 4D structure where any moment can be computed on demand. Shut it down for…

Hi HN, I’ve always been fascinated by space and how much is happening beyond what we usually see day to day. I wanted a simple way to explore space photography and learn what I was actually looking at, without jumping between lots of different sites or long articles. So I built DailySpace, an Android app for exploring a large collection of space photos with short and clear explanations. You can browse thousands of images of galaxies, nebulae, planets, stars, black holes, Earth, and different NASA missions organized into categories or found through search. As I kept using it myself, I added…
