Peasants in the re-taken Somme District work in the fields, circa 1916- 1917, in this Library of Congress handout photo. For women 100 years ago, opportunities to work beyond the home and take part in political life were very limited. As the 20th century progressed, hard-won progress included gradually improved voting rights, while the upheaval of war pushed doors ajar as women worked as part of the war effort. U.S. Library of Congress archive photos show women's workplaces ranging from a flour mill in England to a coal mine in Belgium or Lincoln Motor Co.'s welding department in Detroit. International Women's Day is celebrated on March 8. (Photo by Reuters/Bain Collection/Library of Congress)

“Echus Chasma is a chasma in the Lunae Planum high plateau north of the Valles Marineris canyon system of Mars. Clay has been found in Echus Chasma that means that water once sat there for a time. Echus Chasma is approximately 100 km long and 10 km wide, with valleys ranging in depth from around 1 km to 4 km”. – Wikipedia

Photo: In this handout image supplied by the European Space Agency (ESA) on July 16, 2008, The Echus Chasma, one of the largest water source regions on Mars, is pictured from ESA's Mars Express. The data was acquired on September 25, 2005. The dark material shows a network of light-coloured, incised valleys that look similar to drainage networks known on Earth. It is still debated whether the valleys originate from precipitation, groundwater springs or liquid or magma flows on the surface. (Photo by ESA via Getty Images)

Chloe lived with her mother on a council estate before she auditioned for the X Factor and became a playboy model. (Photo by Palace Lee)

Merit Prize Winner: “A Well Earned Rest in the Sahara”. This photo of Moussa Macher, our Tuareg guide, was taken at the summit of Tin-Merzouga, the largest dune (or erg) in the Tadrat region of the Sahara desert in southern Algeria. Moussa rested while waiting for us to finish our 45-minute struggle to the top. It only took ten minutes of rolling, running, and jumping to get back down. The Tadrat is part of the Tassili N'Ajjer National Park World Heritage area, famous for its red sand and engravings and rock paintings of cattle, elephants, giraffes, and rhinos that lived there when the climate was milder. Photo location: Summit of Tin-Merzouga, Tadrat, Tassili N'Ajjer National Park, Algeria. (Photo and caption by Evan Cole/National Geographic Photo Contest)

These goats threw caution to the wind and scaled this Argan tree right to the very top, even balancing on the most unsturdy of branches. It looks like a bit of a baa-lancing act, but the goats hooves are perfectly adapted to climbing the trees, where they graze on the Argan fruit. Amateur photographer Burak Senbak, 51, took these photos whilst travelling through Morocco in July 2016. Burak is originally from Turkey and works as a mechanical engineer, but has pursued his passion for photography for 10 years. Intrigued by the sight of goats in a tree, Burak couldnt resist the opportunity to take some photos, and said the goats proved a perfect subject. (Photo by Burak Senbak/Caters News)

In this Wednesday, August 21, 1991 file photo, appreciative muscovites hand bread, sausages and flowers to a Soviet tank's driver who helped stop the failed hardline coup in Moscow, Russia. When a group of top Communist officials ousted Soviet leader Mikhail Gorbachev 30 years ago and flooded Moscow with tanks, the world held its breath, fearing a rollback on liberal reforms and a return to the Cold War confrontation. But the August 1991 coup collapsed in just three days, precipitating the breakup of the Soviet Union that plotters said they were trying to prevent. (Photo by Czarek Sokolowski/AP Photo/File)

A picture made with a tilt-shift lens shows “Dwarf Empire” cast member 19-year-old Han Zhen Yan posing in her fairy costume backstage outside one of the fairy tale-like houses at the Dwarf Empire theme park outside Kunming, China's Yunnan province, 04 April 2013. The Dwarf Empire theme park opened in mid-2009, employing a number of dwarves to create the show. Depending on what type of job they do at the park, employees earn between 800-2,000 CNY (100-250 Euros) per month, most of which goes towards their savings as lodging is provided, and their living quarters are equipped with kitchens where they prepare their own meals.
