Planetarium-style visuals, generated live
Dome-adjacent, deep-space imagery generated from music in real time — for science centres, school astronomy evenings, projector nights and anyone who wants the sky to move with the sound.
Who this is for
- Science centres and school astronomy clubs
- Projector and dome events
- Astronomy channels
Astronomy you can point at
A gravitationally lensed black hole with a photon ring, a volumetric nebula lit from a star inside it, a spiral galaxy with dust lanes, and deep-field objects at three parallax depths.
Explain it while it runs
Because every element is bound to something specific in the sound, it doubles as a teaching visual: this ring is this frequency, this flare is the kick.
Runs off one laptop
Fullscreen on a projector, hide the interface, and drive scenes from a phone so nobody has to stand at the machine.
How to do it
- Open Galaxy — it runs in the browser on WebGL
- Choose a song or play the demo
- Pick a cosmic scene and add your logo or title
- Record, or export an MP4 at 1080p–4K
