The artificial peninsula and islands that make up Palm Jumeirah in Dubai as seen from the International Space Station. This massive earthwork is reclaimed from Dubai's Persian Gulf coast. Advertised as "being visible from the Moon," the palm-shaped structure displays 17 huge fronds framed by an 11-km (7 mi) protective barrier. It is the first of three residential and commercial palm-shaped projects being undertaken in Dubai. Image courtesy of NASA.
