Stunning images taken from space to border the night and the day on Earth

Weather of Arabia - NASA astronaut Bob Pinkin took a stunning picture showing the boundary between day and night on Earth .

Pinkin, who has been on the International Space Station for nearly a month, posted the photos via a Tweet on Twitter and accompanied her by saying: "My favorite viewers of our planet that capture the boundaries between day and night."

But some of the "flatland" theory seized the opportunity to question the validity of the picture, which clearly shows that our planet is round .
