THe planet Gliese seems to have the likelyhood of liquid water.
It orbits a red dwarf. A red dwarf star outnumbers a yellow star such as ours by a factor of a million. They are so mumerous that the life that may evolve there would have much in common with all the other red dwaref suns.

So... as I have speculated for decades, the eyes of life forms on such planets would be huge compared to ours due to the dim light.
This correlates with the common tale of aliens having large eyes.

Picture the entire electromagnetic spectrum as being 2,000 miles long. The area we see as visible light is about TWO INCHES long out of that entire 2,000 mile long spectrum.
