If that's a current photo, then we have to realize that it's winter in the northern hemisphere. That explains the brown. Notice that the Southeast, where there are more evergreens, is still fairly green.

How brown the land is. What happened to all the green?

Thanks for the info Cane. I posted the sun pics. I didn't realize their was an astronomy group. I've posted lots of space-related posts over in the Science group, if anyone is interested.

@George - Orbital planes have to do with the gravitational collapse of a cloud (nebula). The collapse causes a spin, but there is nothing specific that controls in what direction the spin will occur. I believe it is random.

@Cane - Obital planes are almost always going to be tilted related to other orbital planes because it is unlikely for them to align exactly.  Just like the axis of the earth's spin is tilted with respect to the earth's orbit around the Sun.

Thanks Rich. Would you offer a reason or two why you believe that?

I believe that the ecliptic and the plane of the galaxy are not the same.
