Amazing: This is a photo taken from a hobbyist balloon last summer. The balloon is at 23+ miles (36km) altitude, which is 3-4 times as high as most commercial jets fly, well into the stratosphere, and about as high as a balloon can go. To a human at that altitude, it'd effectively be about the same as being in space.
Some of the apparent curvature of the Earth is from a wide-angle camera lens, but it's still way,
way up there, and astonishing for backyard science, done by a bunch of buddies, just for fun!
