Star trails form over the Memorial House of the Bulgarian Communist Party on mount Buzludzha in this long exposure picture taken on September 12, 2014. The monument was officially opened in 1981 by the Bulgarian Communist regime to mark 100 years of the set up of an organised Socialist movement, a predecessor of the Bulgarian Communist Party. The monument, no longer maintained by the Bulgarian government after the fall of the Communist regime in 1989, is now abandoned and vandalized. (Photo by Stoyan Nenov/Reuters)

Auxiliary Territorial Service (ATS) plotters at work at Coastal Artillery Headquarters in Dover, December 1942. The Auxiliary Territorial Service was the women's branch of the British Army during the Second World War. It was formed on 9 September 1938, initially as a women's voluntary service, and existed until 1 February 1949, when it was merged into the Women's Royal Army Corps. The ATS had its roots in the Women's Auxiliary Army Corps (WAAC), which was formed in 1917 as a voluntary service. During the First World War its members served in a number of jobs including clerks, cooks, telephonists and waitresses. The WAAC was disbanded after four years in 1921.

These are the spectacular snaps of swirling star trails which transform the night sky into a kaleidoscope of color. Keen photographer Evgeniy Zaytsev, 24, captured the stunning shots on trips to Crimea, Altai and Murom, Russia. The pictures of circular star trails are formed by merging multiple photos taken over the course of several hours. Movement of the Earth causes the stars appear in different places in each image. Here: vibrate, colorful star trails over an abandoned beach house. (Photo by Evgeniy Zaytsev/Caters News)

In this Tuesday, February 11, 2014, photo, a trained monkey, that makes a living for her Pakistani owner by performing to a crowd in public and private places, sits held by a leash, in Rawalpindi, Pakistan. For Pakistanis who raise and train the monkeys they are an important source of income in an impoverished country, and they form a strong bond with the animals. The monkeys are usually captured in the wild when they are babies and then trained. A trained monkey can fetch 20,000 to 30,000 rupees ($190 to $285). (Photo by Muhammed Muheisen/Associated Press)

An infrared portrait from NASA's Spitzer Space Telescope which shows generations of stars is seen in this undated NASA handout image released February 14, 2013. In this wispy star-forming region, called W5, the oldest stars can be seen as blue dots in the centers of the two hollow cavities (other blue dots are background and foreground stars not associated with the region). Red shows heated dust that pervades the region's cavities, while green highlights dense clouds. (Photo by NASA/Reuters/JPL-Caltech/Harvard-Smithsonian/Handout)
