What are some of the largest stars and is there a Hubble or similar
example? thanks, pennwalt

Sam Wormley:
Can you be more specific with the term "largest"?

Biggest? Most bodacious? Hugest?, Grandest?, Most gigantic?

Immense? It seemed obvious enough to me that he meant diameter, because
that's what "largest" means when speaking of a sphere in every-day
language.

He could also mean largest mass, or apparent angular diameter viewed
from Earth. Betelgeuse is cute since there is a Hubble picture of it.

There are very few stars resolvable to a disk from the Earth.

Astronomers tend to think of stars classified by mass since that is what
determines their evolutionary path and at different phases they vary in
diameter by a considerable range.
