Looking Farther (25) – A Frigid Solar System
A frigid solar system? Isn’t that somewhat oxymoronic? Our very own planet has vast sheets of ice on it. And the above pic of Jupiter’s moon, Europa, shows ice tracks.
Biological life may prove to be something of a Goldilocks phenomenon. This planet is too cold; this planet is too hot; but this planet is just right.
How broad a range is “just right”? I don’t think we have an answer to that. Not yet.
