Turn your Mac screensaver into a live view of solar activity. Real NASA footage. Fresh every few hours.
No signup. No payment. Just download and install.
Remember when screensavers were exciting? Now it's just floating colors or old photos.
Your Mac deserves better.
Right now, NASA telescopes are filming the Sun from space. Solar flares. Plasma eruptions. Magnetic storms. It's happening every single day.
Why not watch it on your screen?
Solar Activity Screensaver connects to NASA's solar telescopes. It downloads a fresh 24-hour movie of the Sun and plays it when your Mac goes idle.
You see what happened on the Sun today. Not stock footage. Not animations. The real thing.
It updates itself every few hours. You don't have to do anything.
Actual footage from NASA's Solar Dynamics Observatory. The same images scientists use to track solar weather.

Uses less than 5% of your CPU. Under 100 MB of memory. You won't notice it running.
