Neutron stars are amazing, and I'm a big fan. Couple of Neutron star facts - they're the size of a city but have mass of our sun and then some - they can spin up to 700 times per second on their axis. - they're the strongest magnets in the universe - they are responsible for creating the heaviest atoms - Mass of one neutron star teaspoon is about 100 million tons - they will outlive almost everything in the universe - Even though called stars they're not made of gas nor are they capable of nuclear fusion.
The artwork itself is Chris Butler's depiction of Pulsar from a nearby planet. Probably should point out this is not an epilepsy safe wallpaper. Also High GPU usage on my RX 560, will optimize how I can but no promises.
Update - Added more particles - The sky is moving now, simulating planet orbiting - Added options to control effects - 3D-Like Effect for Neutron star (if Ray option is disabled) - More cool effects
And a tip, do not enable Radeon Anti-Lag for Wallpaper Engine, it will massively increase Gpu usage
