Very interesting ideas. I read this as a perspective possibility as far back is 20 years ago, during a nerdout phase where I was setting up a science fiction game. The idea has always really intrigued me, that there can be a planet where there's this narrow band of habitability scorching death heat of the sunglasses side and the infinite coldness of the dark side

Imagine the science fiction distant future where we could live on such a world, you live in a city that's quite comfortable, but if you go to one side of the extremes of the city the temperature drops 10°, and the other side it raises 10 degrees. While 10 kilometers inone direction and your at a pleasantly hot artificial beach, but 10 km the other way you can go skiing.

Kinda sweet :)

If simple life is as common as I would like to believe it is, I suspect there are many primitive organisms who are surviving on such environments. Not as convinced that such an environment would be well suited to the development of advanced life, but maybe I mean at the end of the day, we really have no idea.

But it's fun to think about

Very fascinating findings for those who believe in aliens!

I think aliens do exist but they’re certainly not concerned with us. If interstellar travel is possible, it would have to be done beyond the confines of matter. Not to get too metaphysical but since we’re talking about aliens, I think they’d travel in ways we cannot comprehend and most definitely not in some kind of human-perspective space car.

This is still only in the range of Life As We Know It. We literally do not know the range of Life Other Than That, although it's suspected that it requires a certain range of chaos -- that is, a reasonably consistent range of energy transfer in a consistent environment.

Life seems to need environmental energy being used to create and perpetuate (and, probably, replicate) patterned formations. We don't know that it has to be water-based, or even chemical. Electromagnetic-pattern lifeforms could exist, for all we know, just for instance, so it may be that most life in the universe exists entirely within stellar bodies.

Or not. But we don't know. It could be that most life on Earth exists in the hot rock miles beneath the surface and isn't water-based at all.

Still, we're probably mostly interested in water-based life that's at least pretty much Life As We Know It. Unless deep hot-rock organisms ever breach the surface, in which case we'd be very interested in that, especially if they're quite large.
