Red Sun

Fairly certain Superman would hate me right now. XD I altered this one a little from the others. I managed to adjust the color levels on the corona or whatever part has the larger flares off the surface, and made it so that they looked just a little more visible and flame like.
Oh yeah, and I've got a theory that Krypton's sun is likely to be named Rao. He's a god that Superman's people worshiped (I believe) and if human history is a good basis for learning about some alien life, it's that the sun would have a god assigned to it, like Egypt had the sun god Ra (probably where the name Rao came from for the comics if you ask me).
