The Tree Projects team spent 67 days documenting one eucalyptus regnans in the Styx valley of Tasmania. Using a combination of tree-climbing and elaborate arboreal rigging techniques, they produced an intimate portrait from an impossible perspective of one of the world’s largest individual flowering trees, which goes by several common names. These photos document the process that resulted in an extraordinary ultra high-definition photograph. Here: Haley nears the top of the tree. (Photo by Steven Pearce/The Tree Projects/The Guardian)

“Getting to see girls’ bedrooms must have been a teenage obsession for the members of the all-male photographic collective Riverboom. Now that they have more or less grown up, they have decided to transform that dream into a reality. Riverboom’s Gabriele Galimberti and Edoardo Delille are traveling the five continents to see where girls, between the ages of 18 and 30, sleep. They have discovered that girls’ bedrooms are much more then just places where they lay down their heads – they are the places where girls read, love, dream, work and play”. – Gabriele Galimberti.

“William Hope (1863 – 8 March 1933) was a pioneer of so-called “spirit photography” (spirit photography is a type of photography whose primary attempt is to capture images of ghosts and other spiritual entities, especially in ghost hunting). Based in Crewe, England, he was a member of the well known spiritualists group, the Crewe Circle”. – Wikipedia

This undated image provided by World View shows World View capsule and balloon spacecraft that will rise to 100,000 feet above Earth for passengers to see the curvature of the planet and the blackness of space. Space tourism companies are employing designs including winged vehicles, vertical rockets with capsules and high-altitude balloons. While developers envision ultimately taking people to orbiting habitats, the moon or beyond, the immediate future involves short flights into or near the lowest reaches of space without going into orbit.

These illustrations are the work of an artist who has put a sinister spin on iconic animations in order to highlight the disturbing realities of domestic abuse. No Violence Against Women is a project by Italian artist and activist AleXsandro Palombo, 40, who is based in Milan.

Dan surrounded by seven days of her own rubbish in Pasadena, California. If you've never thought about how much rubbish you throw away an honest photographic series will open your eyes. Men, women, couples and families with young children have been photographed lying on their backs surrounded by a week's worth of their own rubbish – from old cartons of milk, used nappies and even tampons. The startling series “Seven Days of Garbage” by Californian photographer Gregg Segal is an unforgettable reminder of the amount of waste a human collects in just seven days.

This barking set of images takes the saying “dogs look like their owners” to the ultimate conclusion. Photographer Sebastian Magnani, 28, has cleverly spliced the features of four-legged friends with the head and shoulders of their owners. In a series called “Underdogs”, the Swiss photographer shot the owners and their respective pets in the same portrait style. Then he used expert photo-manipulation techniques to seamlessly transplant the canine faces onto the human bodies. (Photo by Sebastian Magnani)
