“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

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)

“Mehndi or menhdi is the application of henna as a temporary form of skin decoration in India, as well as by expatriate communities from the country. The word mehndi is derived from the Sanskrit word mendhikā. The use of mehndi and turmeric is described in the earliest Vedic ritual books. Haldi (Staining oneself with turmeric paste) as well as mehndi are important Vedic customs as a symbolic representation of the Outer and the Inner Sun. Vedic customs are meant to awaken the “inner light” and so the gold of the inner Sun has an important symbolic function”. – Wikipedia

Roza Khamitova was born into a family of artists in Kazakhstan. After finishing design school in Manhattan, New York, she was working in fashion industry for about 8 years. As a visual artist Roza had always drawn most of her inspiration from the natural world around her in the mountains of Kazakhstan. In 2011 she launched Shovava, her personal line of women’s clothing based on her hand drawn paintings and prints of the animals, plants and patterns found in nature. Roza was enchanted by the beauty of wings, its structure and symbolism. First, she sketches big wide-spread wings on paper with a light pencil, adds black ink to create a three-dimensional feel and fills with stunning watercolors.

A photographer is using a unique method to show the shift from day to night across famous cities in spectacular images. Daniel Marker-Moors' take on time-lapse photography – which he calls time slice – sees the photographer snap image after image, before combining them to create beautiful, vibrant works. His images usually focus on a point in the day with the most dramatic change in light, such as sunrise or sunset. Marker-Moors, from Los Angeles, begins by shooting hundreds and sometimes thousands of images from the same spot. Here: Chicago – 35 photographs, 15 minutes.

Runner-up. “The heavens opened and the streets around Shibuya, Tokyo, were suddenly drenched in even more colour and movement. I was taking photos (my friend was holding the umbrella) when I noticed this woman at the crossing. I’m pleased with the futuristic feel of the image”. (Photo by Katherine Bridgestock/The Guardian)

A makeshift cart with containers is seen at a suspected drug tunnel under construction during a media tour by Mexican Army in Tijuana April 7, 2015. Mexican soldiers foiled the construction of a suspected drug tunnel underneath a house near the U.S. border, arresting nine people and impounding a truck used to clear debris, the Army said on Tuesday. Wired with lights, the tunnel was being built next to the Tijuana border crossing, south of San Diego, California, and near a Mexican air force installation as well as a regional federal police facility.

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.

Some of the best entries so far in the 2016 Insight Astronomy Photographer of the Year competition. There are two weeks left to enter, and the winners will be announced in September. Here: Aurora over Laksvatn Fjord, Laksvatn, Norway. The aurora borealis dances in the skies over the town of Laksvatn, with the Milky Way to the left. The image is a single shot with no compositing, only post-processing to bring out the aurora, and some colour corrections. The photographer Matt Walford said: “I love the way the northern lights look like they are just wistfully dancing over the fjord, framed by the mountains on either side”.
