An art installation has created the optical illusion that the French capital's Eiffel Tower is perched precariously over a rocky ravine.
The artwork, by an artist who uses the pseudonym JR, involved laying an image of a ravine, and the pillars that form the base of the Eiffel Tower, onto the floor of an esplanade that overlooks the tower.
When a visitor stands in the right spot, the artwork in the foreground and the tower in the background line up with each other, and the illusion is created.
"I think it's really cool because it's really realistic," said one visitor, Lara Watson.
"I like that it combines with the Eiffel Tower, so the piece of art becomes a piece of art because of the Eiffel Tower already behind it."
Other work by the same artist includes an installation at the US-Mexico border wall that appears to show a giant baby peering over the wall, and an optical illusion that made it appear a chasm had opened up in the courtyard of the Louvre museum in Paris.
The world's first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.
Cassius, the 5.48-meter (18-foot) saltwater crocodile known as the world’s largest in captivity, has died at an estimated age of over 110 years, as reported by Marineland Melanesia Crocodile Habitat in Australia.
Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million years ago during the Jurassic Period.
Surmising even the physical appearance of a dinosaur - or any extinct animal - based on its fossils is a tricky proposition, with so many uncertainties involved. Assessing a dinosaur's intelligence, considering the innumerable factors contributing to that trait, is exponentially more difficult.
