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.

Meirav Stardinner receives a snake massage from Ada Barak at Barak's snake spa on September 11, 2008 in Talmei Elazar, Israel. Barack's income comes mostly from exhibiting her plants which eat everything from insects to small mammals. She discovered snakes' therapeutic value after letting people hold them after her act “Some people said that holding the snakes made them feel better, relaxed”, she says. “One old lady said it was soothing, like a cold compress”. Now she uses a combination of big snakes for deep massage and little ones for light massage, though all are non-venemous. (Photo by Uriel Sinai/Getty Images)

“Echus Chasma is a chasma in the Lunae Planum high plateau north of the Valles Marineris canyon system of Mars. Clay has been found in Echus Chasma that means that water once sat there for a time. Echus Chasma is approximately 100 km long and 10 km wide, with valleys ranging in depth from around 1 km to 4 km”. – Wikipedia

The data was acquired on September 25, 2005. The dark material shows a network of light-coloured, incised valleys that look similar to drainage networks known on Earth. It is still debated whether the valleys originate from precipitation, groundwater springs or liquid or magma flows on the surface. (Photo by ESA via Getty Images)

“The Dream Chaser is a planned crewed suborbital and orbital vertical-takeoff, horizontal-landing (VTHL) lifting-body spaceplane being developed by SpaceDev, a wholly owned subsidiary of Sierra Nevada Corporation (SNC). The Dream Chaser design is planned to carry seven people to and from low earth orbit. The vehicle would launch vertically on an Atlas V and land horizontally on conventional runways”. – Wikipedia

Sierra Nevada's Dream Chaser spacecraft is under development with support from NASA's Commercial Crew Development Program to provide crew transportation to and from low Earth orbit. NASA is helping private companies develop innovative technologies to ensure that the U.S. remains competitive in future space endeavors. (Photo by Bill Ingalls/NASA via Getty Images)

“Reem Riyashi (1982 – 14 January 2004) was a Palestinian mother of two from Gaza City who killed herself and four Israelis at the Erez crossing on January 14, 2004 in a suicide bombing attack. Hamas and the Al-Aqsa Martyrs Brigade claimed that the attack by Riyashi was a joint operation mounted as a response to weeks of Israeli incursions into West Bank cities that had left about 25 Palestinians dead”. – Wikipedia

“The Berlin Wall (German: Berliner Mauer) was a barrier constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off West Berlin from surrounding East Germany and from East Berlin. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the “death strip”) that contained anti-vehicle trenches, “fakir beds” and other defenses. The Soviet-dominated Eastern Bloc officially claimed that the wall was erected to protect its population from fascist elements conspiring to prevent the “will of the people” in building a socialist state in East Germany. However, in practice, the Wall served to prevent the massive emigration and defection that marked Germany and the communist Eastern Bloc during the post-World War II period”. – Wikipedia

Members of the Michiana Rocketry prep a 10-foot, 450 pound porta-potty, mounted on rocket motors for launching, Saturday, December 6, 2014, from a field in Three Oaks, Mich. It made an arc and almost landed on a spectator’s pickup truck, 2,000 feet away. A group of Michiana Rocketry club members planned the project for more than two years. The club is trying to increase awareness of rocketry as a hobby and prove it’s possible to turn a porta-potty into a rocket and launch it successfully. About 30 people worked on the rocket, from engineers to sales people who lined up sponsors. (Photo by Don Campbell/AP Photo/The Herald-Palladium)

This is the stunning body of work by a talented painter – who transforms humans into amazing animals. From alligators to foxes and even owls, artist Shannon Holt, 39, paints every little detail on models to turn them into wildlife. The incredible paintings, which take anywhere between six to 12.5 hours to complete, are part of her Florida Wildlife Series. Shannon, from DeLand, Florida, previously worked on different surfaces such as glass, metals and wood. But the animal advocate decided to experiment with human canvasses and incorporate animals in her work. Here: Red Fox. (Photo by Ryder Gledhill/Shannon Holt/Caters News)
