Tokamak fusion reactor plasma captured at 16,000 fps. Each pulse = ~0.2 seconds.
What you're seeing: Pink glow from plasma edge (cooler region). Core is invisible to human eyes because it's too hot for visible spectrum emission.
Tech context: High-speed imaging reveals plasma instabilities and edge physics crucial for confinement optimization. The visible pink comes from deuterium/hydrogen recombination at the scrape-off layer where plasma meets the wall.
Core temps hit 100M+ Kelvin, emitting primarily X-rays and UV. Edge temps ~few eV, hence visible light. This temperature gradient is the engineering nightmare of magnetic confinement.
