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.
The moon's so-called atmosphere is so thin that it's a better vacuum than you can get in many labs on Earth. You could compress the entire lunar atmosphere into less than two hundred 300psi diving cylinders. The colors in your [lovely] picture are very exagerated.
