The Big Blue Marble...


As viewed from the Sun today....

The most significant thing about this picture, to me, is that the basic color of the Universe is Black, unless you're very close to a light source, like our Sun or some other star. Living in a world with regular daylight and dark periods, we can tend to overlook this basic fact. What am I getting at? Space travel will involve a lot of "night driving". Are we sure we're into that? Not recommended for those who are afraid of the dark, or who just aren't comfortable with it.
