An Indian Hindu widow smeared with colors sits and watches others playing during Holi celebrations at the Gopinath temple, 180 kilometres (112 miles) south-east of New Delhi, India Monday, March 21, 2016. A few years ago this joyful celebration was forbidden for Hindu widows. Like hundreds of thousands of observant Hindu women they would have been expected to live out their days in quiet worship, dressed only in white, their very presence being considered inauspicious for all religious festivities.

It's taken roughly five months, but a massive iceberg has separated from Antarctica's Pine Island Glacier. According to NASA's Earth Observatory, the estimated size of this iceberg, named B-31, is around 660 square kilometres (33 km long by 20 km wide) – a city-sized block of ice that has slowly migrated away from the continent, and is now floating out to sea. Take a look at some massive icebergs afloat in the oceans. Photo: File photo of an iceberg floating near a harbour in the town of Kulusuk, east Greenland August 1, 2009.

The galactic core of the milky way occupied by two small wooden boats on July 2, 2014, in Isle of Wight, UK. The Milky Way shines in mesmerizing colourful patterns above the Isle of Wight in stunning photographs. Chad Powell used a DSLR camera to capture images of the spectacular constellation above the familiar beach scenes of England's largest island. The 22-year-old, who shot the pictures over a year of stargazing on the island, often stayed up until dawn to catch the most dramatic sky-scapes. Chad, a graphic designer from Ventnor, Isle of Wight, used foregrounds of abandoned theme parks, harbors and lighthouses against the illuminated sky. Minor adjustments were made to bring out the contrast and whites in the images. (Photo by Chad Powell/Barcroft Media)

Back in 2010, French photographer Antoine Bruy began hitchhiking around Europe without any fixed route. Along his travels, he met people who had entirely abandoned city life in favour of an isolated country existence they found more fulfilling. Bruy began seeking out people who lived off-the-grid. After three years on the road, staying in makeshift houses and on community farms, he has released Scrublands, a documentation of the lifestyle. While each living situation is different, Bruy found that all the people he met shared a common desire to escape the rat race and achieve a quieter life in harmony with nature.

A Ka'apor Indian warrior (L) chases a logger who tried to escape after they captured him during a jungle expedition to search for and expel loggers from the Alto Turiacu Indian territory, near the Centro do Guilherme municipality in the northeast of Maranhao state in the Amazon basin, August 7, 2014. Tired of what they say is a lack of sufficient government assistance in keeping loggers off their land, the Ka'apor Indians, who along with four other tribes are the legal inhabitants and caretakers of the territory, have sent their warriors out to expel all loggers they find and set up monitoring camps in the areas that are being illegally exploited.
