It is already one of the world’s most iconic cities, but this incredible collection shows how much Paris has changed over the course of the past century. The collection, by French photographer Julien Knez, shows Paris in the 1940s against a backdrop of how the same places look today. Knez says he put the striking collection together to celebrate the 71st anniversary of the city’s liberation from Nazi control in August 1944. Here: Soldiers outside the Hotel De Ville in the 1940s.

Photographer Khalid Alhammadi really has got his head in the clouds as he scales some of the Middle East’s tallest buildings to photograph iconic landmarks high above the rising mist. Khalid’s breathtaking shots over Abu Dhabi look almost otherworldly, with skyscraper tips and mosque towers poking through the eerie fog. Here: Night view of Abu Dhabi.

They might look like something straight out of a horror film, but these extraordinary images have been created to show the special bond between cats and their owners. Photographer Sebastian Magnani, 28, from Brig, Switzerland, took pictures of dogs and their owners using the same position and camera settings before working his magic with editing software. The result is this startling set of images, which show the pooches with human clothes – one wearing a hoodie, another with a red coat, one with a shirt and cardigan, and another with a blue jacket.

Sculptor Ben Young (previously) just unveiled a collection of new glass sculptures prior to the Sculpture Objects Functional Art + Design (SOFA) Fair in Chicago next month. Young works with laminated clear float glass atop cast concrete bases to create cross-section views of ocean waves that look somewhat like patterns in topographical charts. The self-taught artist is currently based in Sydney but was raised in Waihi Beach, New Zealand, where the local landscape and surroundings greatly inspired his art.

A cat Loki with a pair of distinctive fangs has quickly become one of the most famous felines on Instagram thanks to evil-looking face. Loki, who now has more than 23,000 followers online, was adopted from a cat shelter by her owner Kaet, who explained on in a posting that she knows very little about the cat’s distinctive appearance. Adopted from a cat shelter, nothing was mentioned to his owner Kaet about her kitten's unique features.

Shimmering clearest blue and stretching as far as the eye can see, this is one of Iceland's famed crystal ice caves. The giant solid waves look frozen in time but they are slowly moving along as part of the Vatnajokull Glacier – which stretches across eight per cent of the island. The images were captured in February 2014 by British photographer Rob Lott, 49. Photo: A wide view of Rob Lott in the crystal ice cave in the Vatnajokull Glacier, Iceland.

Snakes wearing hats is now an internet meme and it’s kind of cute but also kind of terrifying. I don’t know about you, but I don’t think there’s anything more evil than a giant cartoon snake wearing a bowler hat – the hat just makes it even more sinister. As you can see below, some of these snakes look cool and cute, but some of them are pretty frightening. Either way the addition of a dumb hat definitely has an effect on them. I definitely won’t be getting a pet snake any time soon.
