There will be a wide twilight and sunset band with temperatures comfortable for humans, but perhaps not enough light for photosynthesis. I believe some micro organisms thrive at 122 degees f and some large creatures live at much higher temperatures and very high pressure near ocean bottom vents. Neil

If a planet is tide locked to it's star, the center of the hot side is perhaps 122 degrees f = 50 degrees c. The center of the cold dark side perhaps minus 5 degrees c = 23 degrees f. This will produce a great glacier = ice cap near the center of the dark side. If too little water remains for the ho...

There are several reasons why humans or other beings might want to live in caves, far below the surface of Mars. Warmer 2 higher air pressure 3 water 4 reduced radiation 5 filter out the super oxide dust They could use grow lights to grow food that requires photosynthesis. There is little present ev...
