I was reading a little article about Betelgeuse, the mental red giant star in Orion, where they said they’d had data which indicated it was spinning at 3-4 miles per second. 
This goes against everything they thought was possible, so they looked again at the data. 
( they measure the speed of star rotation based on the fact that light coming from the side which is spinning towards us gets a little boost over the light from the side going away from us, from this they can calculate it’s rotation speed.)

 

It seems that it’s (probably) not spinning that fast ( but it might be), but what skewed the data was the fact that the convection cells on it are just ridiculous. 
 

On the Sun, they’re about the size of Texas…

On Betelgeuse, they can be as big as the Earth’s orbit around the Sun! 
 

The thing is fucking huge, it would go out past Jupiter if it was in our system! 
 

And it’s kicking off :lol:
