Both Devil’s Breath and Devil’s Snot are more acceptable names for them. These are large, unpleasant plants. Expect the plants to be at least a meter (3 feet) across if you reside in […]

When the sun sets at night, assorted constellations reveal themselves against the black soup of space. As the night progresses, some of these constellations set below the horizon, and others rise to take their places.

On a dark, cloudless night, we can see thousands of stars scattered across the inky black soup of night. If you look at the stars long enough, you might imagine that you can see simple pictures of people, animals, weapons, and much more.
