Several cosmic characteristics, including the lack of an atmosphere, lend space its dark color.

Blame plate tectonics for Earth’s mountains, earthquakes, volcanoes, and why its continents fit together like pieces of a giant jigsaw puzzle.
Cheetahs are unique members of the big cat family, with bodies built for acceleration and short bursts of incredible speed.
