23 HDRI 8K Galactic Energy Space Skyboxes

Vivid galaxies and bursts of energy, full of saturated purple, blue and fire orange. This is space with the colour turned up, for sci-fi that wants to look dramatic and not scientific.

You get spiral galaxies in files 03, 08 and 11, thin bright bands running around the horizon in files 02 and 14 to 16, branching pink lightning in file 12, and two fierce red and orange skies in files 20 and 21. Bright flares sit near the centre of many views.

Ideal for:
- Arcade space shooters and sci-fi menus
- Bold key art and thumbnails
- Portals, warp scenes and boss arenas
- VR space experiences

What you download:
- 23 .HDR panoramas at 8192 x 4096, 2:1 equirectangular

Every HDR image was checked for bad pixels, and the edges were checked at the join. Detail is soft when viewed at 100%, so these suit skies and backdrops better than extreme close-ups. Peak brightness is about 1.0, so they look their best as visible backgrounds. For strong sun shadows, add your own directional light.
