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...
