"On April 12th, 1961, Soviet cosmonaut Yuri Alexseyevich Gagarin became the first human in space. His remotely controlled Vostok 1 spacecraft lofted him to an altitude of 200 miles and carried him once around planet Earth. Commenting on the first view from space he reported, "The sky is very dark; the Earth is bluish. Everything is seen very clearly". Alan Shepard, the first US astronaut, would not be launched until almost a month later and then on a comparatively short suborbital flight."
See a much better version of the picture at the Astronomy Picture of the Day (APOD) page, which shows much more subtle detail.
