Thanks, JadeStar, for sharing that lively, very informative video. Hank Green seems quite pessimistic about the chances for life on a tidally locked
planet. As we have seen, atmospheric and oceanic circulation of heat from the hot side to the cold one might moderate temperature extremes enough to
make such a planet livable.
Such a world could have an interesting physical geography. The sub-solar point would probably still be somewhat torrid, like our equatorial zone, and
the anti-solar point frigid, like either of Earth's poles. Its temperate zone would be in a the ring of perpetual twilight, equidistant between the
hottest and coldest points.
There might be a huge, planet-wide convection cell carrying rising and expanding hot air to the cold side of the planet, with cold air being pushed
by it back to the hot side, to be heated again.
