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.
Saturnâs largest moon, Titan, has a thick atmosphere made mostly of nitrogen and methane. The way sunlight breaks up methane in Titanâs ionosphere helps give the moon an orange color. Most celestial bodies, including all the asteroids in the asteroid belt and our own moon, do not have atmospheres.
