This video of star sizes in scale is mindbending.
Me: "Wow. ... Whoa."
Rob: "It's the Total Perspective Vortex."
Betelgeuse is large enough and close enough that Hubble has taken a photo of it and resolved it as more than a point source.
(Those last ones in the video are no longer the largest known stars. VY Canis Majoris is now the largest known star, a red hypergiant over two light-hours in diameter. Size comparison image on this blog.)
