Show HN: Gaia Atlas – Local Stellar Map
Hi there! I made the fan-created Project Hail Mary Star Map and had so much fun with the initial version that I decided to create a v2 that lets you explore our local star system and travel to many more stars. This new version lets you visit dozens of named stars, plan interstellar travel, view exoplanet systems, learn about stellar characteristics, and view 3D constellations. This version also includes 600k stars rendered in-browser with a higher resolution skybox rendered from the GAIA DR3 mission data.
Also, you can now generate links to share what you find! Here is an example of plotting an interstellar course: https://valhovey.github.io/gaia-atlas/?s=61_CYGNI&d=34.9&y=0.9455&p=0.06657&c=0&g=1&o=0&t=1&a=1 https://valhovey.github.io/gaia-atlas/?s=61_CYGNI&d=34.9&y=0...

- tom-wal 4mo agoVery smooth. It reminds me the space navigation in this very old video game “mankind”. I could use this while teaching !

- samtheDamned 4mo agoI like the ability to map out the constellations and see how they connect from different angles. I don't think I've seen something like that before.
- RAZKOM 4mo agoThe parallax on the constellations is something I had never considered before and is awesome to see interactive like this. Makes you wonder if alien planets would come up with their own.
