The Atacama is not really spreading. The geological and atmospheric and oceanic conditions that surround it pretty much limit its spread.
The driest desert is generally seen as being either the Atacama or Antarctic
How far is the Atacama from what? Please be specific.
No, Death Valley is far from the driest area on earth. That distinction goes to Antarctica and the Atacama Desert.

Australia has no native cacti, so there are no cacti occurring naturally in the Great Victoria Desert. However, introduced cacti such as the prickly pear have spread as far west as the Great Victoria Desert.
Penguins live in the sea. They are aqua-dynamic birds. Penguins come to land to breed, where the male stacks loose stones in a sorta-circle and where the female lays eggs. Otherwise, exactly where the animals live is a scientific mystery.

And, of course, about half of the Antarctic Desert is in the Western Hemisphere.
Only the Chihuahuan Desert enters far-west Texas.
How far from what?
Not necessarily. The only desert truly in a frigid zone is Antarctica. Other cold deserts may have a very hot summer but winters that can be bitterly cold. Exampls are the Gobi Desert of China and Mongolia and the Great Basin Desert of the United States,
The desert and the tundra are the driest biomes as far as precipitation.The desert and the tundra are the driest biomes as far as precipitation.
The Gobi Desert is not far from Beijing.
