They’re big. Like, really really big.^1
They’re around 5 light years tall. From a quick back of envelope question, unless I lost a zero somewhere, the clouds could be changing shape at almost 1,000,000 miles an hour and you’d see approx 1% difference in their height.
^1 Well, not big for the galaxy, they’re still a speck against the scale of the galaxy, but big for human experience.
