That image is 600,000,000,000,000 miles or right around 1,000,000,000,000,000 km across. There's just no way to comprehend stuff like that, which hints at the limits of our mental horizons.
Those stars are flying around at stunning speeds, and those clouds are expanding just as fast. Yet over a human lifetime that image will essentially not change at all. So just try to enjoy the bright lights and the pretty (false) colors. We humans are less than a finger snap in the cosmic pageant.
I have seen this object through a telescope, you have to be pretty far south. To human eyes it's all diamonds and white mist. The photons that zapped by neurons that night had been traveling for 170,000 years at 186,000 miles a second to meet me. Of course that's how I perceived the interval, as far as the speed-of-light photons were concerned the journey took no time at all. But enough of this, my monkey-brain is starting to hurt.
