Chromaffin cell. Chromaffin cells, also pheochromocytes, are neuroendocrine cells found mostly in the medulla of the adrenal glands (located above the kidneys) in mammals.
The Moon has no appreciable atmosphere. The sky is always black and the radiation from the Sun strikes with full force on the surface of the Moon. The lack of atmosphere produces temperature extremes on the Moon that range from -250 degrees F in the dark to +250 degrees F in the light.
In terms of life, Titanâthe largest moon of Saturnâhas one thing going for it that none of the other destinations do: a thick, chemically active atmosphere. The moon's atmosphere is denser than Earth's, and the upper levels are mostly composed of nitrogen, with small amounts of methane and oxygen.
