Turn your Mac screensaver into today's solar activity. Straight from NASA's telescope. Updated every hour.
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.
Real solar footage from today. No stock clips. No animations. Just the Sun.
It updates itself every hour. You don't have to do anything.
Actual footage from NASA's Solar Dynamics Observatory. The same images scientists use to track solar weather.
New videos download automatically in the background. Your screensaver shows what the Sun looked like in the last 24 hours.
Uses less than 5% of your CPU. Under 100 MB of memory. You won't notice it running.
Videos are saved locally. No internet? It plays the last downloaded movie.
