To need air is human. Our lungs thank us for each breath we take. But air is more than a transporter of O2. It shapes our weather, keeps birds aloft and moves spores from here to there. A cubic foot of air is anything but “empty” (hot dog grease particles, anyone?).
The same goes for space (minus the hot dog grease). It’s a happening place. Discover why interstellar space is more than a whole lot o’ nothing; and what happens when the Voyager spacecraft leaves our solar system. Plus, catch a skydiver in action!
