“A skydiver has made history by smashing the world record for the highest skydive after leaping from 128,097ft (39,044m). Daredevil Felix Baumgartner ascended to the edge of space in a pressurised capsule suspended beneath a giant helium balloon. He then jumped out, freefalling for four minutes and 19 seconds before opening his parachute”.

The National Geographic Photo Ark is a travelling exhibition of photographer Joel Sartore’s quest to create a photo archive of biodiversity around the world. So far, Sartore has captured studio portraits of more than 6,000 species – a number that he hopes to double. On 1 July, the ark will open at Melbourne zoo – the first time it has been exhibited in the southern hemisphere. More than 50 portraits will be on display, including many of Australian endangered animals being protected by programs at the zoo itself. These captions have been edited from text supplied by Melbourne zoo. Here: Barking owl. (Photo by Joel Sartore/National Geographic Photo Ark/The Guardian)
