A rainbow spans a continuous spectrum of colors; the distinct bands including the number of bands, are an artifact of human color vision, and no banding of any type is seen in a black-and-white photo of a rainbow, only a smooth gradation of intensity to a maximum, then fading to a minimum at the other side of the arc. For colors seen by a normal human eye, the most commonly cited and remembered sequence, in English, is Newton’s sevenfold red, orange, yellow, green, blue, indigo and violet . However, color-blind persons will see fewer colors.Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew. You can see 20 beautiful rainbow images below. Do not forget to tell me through your comment, which one you like most.

World is a global village now but space is still unlimited wide, No one know it’s complete width, measure. It’s true many scientists tried their best to measure it but all of them get failure. Only God knows it’s measure and reality. But if we come to this point what is that, that human being know? Then the answer is that space is incredible, impossible to measure it. We know only this fact that there are nine planets in the space, moon, sun and uncountable stars, we don’t know perfectly how many planets will be discover in space in coming future. How much galaxies, black holes and milky ways will be renown in future but I try to collect some beautiful space images for your inspiration. I hope you will like them and must think about their measure and some points of their reality. In below pictures a few pictures photoshopped but that are only a few.
Bora Bora is an island in the Leeward group of the Society Islands of French Polynesia, an overseas collectivity of France in the Pacific Ocean. The island, located about 230 kilometres (140 mi) northwest of Papeete, is surrounded by a lagoon and a barrier reef. In the center of the island are the remnants of an extinct volcano rising to two peaks, Mount Pahia and Mount Otemanu, the highest point at 727 metres (2,385 ft). The original name of the island in the Tahitian language might be better rendered as Pora Pora, meaning “First Born”; an early transcription found in 18th- and 19th century accounts, is Bolabolla (or “Bollabolla”).
