I've always loved looking at these 2 images. Really gives you a sense of the magnitude of size on some of these stars. You see how small earth is compared to our Sun. Then you see how tiny the Sun is compared to some of the monsters out there. You can understand why, when these hyper giants go hypernova billions of light years away from earth, how they could be brighter then entire galaxies just millions of light years away.
