Guys and gals, i wanna know what you think other stellar surfaces look like, is it possible that red dwarves ---> blue giants all look the same?


What do you say?

By looking the same, do you mean, they all have solar flares and "sun" spots?

Take a butcher's hook at this site, Padawan;

yup, sun spots/granulation


Could there be something on other stellar surfaces that dont exist on the solar surface?

Using the information on the link I gave earlier, Ihave made an image of the surface of Betelgeuse of my own; with the help of Grant Hutchinson and the Celestia space simulator, of course...
here it is;

to me it looks like the granulations on the surface of Betelgeuse are so large they cover about a quarter of a hemisphere each.

Well ... If you include neutron stars, how about 1 cm tall mountains?
