Jacob's Well is a perennial karstic spring in the Texas Hill Country flowing from the bed of Cypress Creek, located northwest of Wimberley, Texas. The twelve foot (four meter) diameter mouth of the spring serves as a popular swimming spot for the local land owners whose properties adjoin Cypress Creek. From the opening in the creek bed, Jacob's Well cave descends vertically for about thirty feet (ten meters), then continues downward at an angle through a series of silted chambers separated by narrow restrictions, finally reaching a depth of one hundred and twenty feet (forty meters). Until the modern era, the Trinity Aquifer-fed natural artesian spring gushed water from the mouth of the cave, with a measured flow in 1924 of one hundred and seventy gallons per second (six hundred and forty liters per second) discharging six feet (two meters) into the air. The spring is the greatest source of water recharging the Edwards Aquifer.

“The scientists behind NASA's $2.5 billion Curiosity rover mission on Mars on Tuesday explained the nature of a tiny, gleaming "flower" embedded in Red Planet rock, and revealed where they'll be using the SUV-sized robot's drill for the first time”. – Alan Boyle via NBCNews.com

Some people think of trolls as nothing but savage beast, yet others realize that beneath their rock-hard skin hides a gentle kind heart. Ivar Rodningem is one of the people who knows the true nature of trolls. Though these creatures look unruly, it is just the way they were born. Trolls come in all shapes and sizes. Some are small, some are large, and some are simply enormous. They help each other out, though elders tend to be loners, preferring the company of their own thoughts to anybody else. You shouldn’t run for your life if you ever meet a troll, though we wouldn’t recommend pestering them, as they are mighty strong, even the little ones.

“Felix Baumgartner (born 20 April 1969 in Salzburg, Austria) is a skydiver and a BASE jumper. He is renowned for the particularly dangerous nature of the stunts he has performed during his career.

In this test he reach the altitude 21800 meters (71500 ft) and landed safely near Roswell. Red Bull Stratos is a mission to the edge of the earths atmosphere, where upon reaching altitude of 120,000 feet by helium baloon, pilot and basejumper Felix Baumgartner will then freefall to the ground in an attempt to break the speed of sound.

“The leopard seal (Hydrurga leptonyx), also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). It is most common in the southern hemisphere along the coast of Antarctica and on most sub-Antarctic islands, but can also be found on the coasts of southern Australia, Tasmania, South Africa, New Zealand, Lord Howe Island, Tierra del Fuego, the Cook Islands, and the Atlantic coast of South America. It can live twenty-six years, possibly more. Orcas and large sharks are the only natural predators of leopard seals”. – Wikipedia

These breath-taking photographs reveal the everyday lives of animals living in the wild. The incredible images were taken by wildlife photographer Wim van dan Heever, from Pretoria, South Africa, during trips to locations including Japan, Botswana and Svalbard. The 43-year-old has been photographing wildlife since he was a young boy and turned his passion for animals into a career and set up ODP Safaris. He has travelled across the globe to photograph wild animals – from lions and tigers, to elephants, dolphins and eagles – as they hunt, give birth and graze in their natural habitats. Here: Lions submerged in water. (Photo by Wim van den Heever/Caters News)

Trainees of the Tianjiao Special Guard/Security Consultant bodyguard training camp watch their instructor use a scarf to cover a student's head during a demonstration of close-quarter combat skills at a special course on flight safety inside a scale model of a passenger jet at a flight attendant training centre on the outskirts of Beijing, March 18, 2014. Inspired by the missing Malaysia Airlines Flight MH370, the company wanted to emphasize the importance of aviation safety by teaching their trainees emergency evacuation procedures and close-quarter combat skills to handle situations such as natural disasters and plane hijacks, according to the company.

French artist Gilbert Legrand’s new series takes everyday objects like corkscrews, tape measures, and more and turns them into hilariously cute characters that almost make you forget their original purpose. Skillfully using each object’s natural shape, he crafts a character full of whimsy and personality. Each is painted to detail, with even the tiniest of characters bearing an expression which leaves no doubt as to their feelings about the situation. It truly takes a talented hand and imagination to turn paint brushes and zippers into humorous characters with surprisingly huge personalities.
