Yes, they are acceptable sources. What's happening on other planets and moons is not driven by the same forces of change as on Earth at present.
Thank you; much food for thought.
I know what it’s like to disagree with Freepers. I often present the view that abstract art can be meaningful, and I’ve presented a series of “lectures” on FR to that end. (They are accessible from my homepage here.) Often I get great deal of flack for appreciating artworks like those of Christo’s Gates in NYC.
My mind is thus a far cry from your scientific bent. But we will try to learn from your page nonetheless.

Oh...so, I guess the other planets in our *solar system* aren’t heated by the same sun as the earth, then?
Riiiight.
