In plain words
The Size of Space is an interactive browser-based visualization that displays the full scale of the universe. Built with Three.js, it allows users to explore and understand the vastness of space through visual representation. The tool is designed for anyone curious about astronomy and the cosmos who wants to grasp the relative sizes and distances of celestial objects in an engaging, interactive format.

Atlas of Space2025 · atlasof.space · ▲770Hello 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…
Galaxy Visualization2024 · github.com · ▲75I've been iterating on a small galaxy visualization project that originally started as a university course assignment, using only provided sample data (no real astronomical distances). Recently, I updated it to include redshift-based distance data, which makes the 3D structure more meaningful and closer to real large-scale galaxy distributions.
