Satellite photos of the world's tallest mountains look like they're taken from an airplane, say the folks at NASA, until you realize these peaks are at about the same altitude that commercial jetliners fly.
Above, more 8,000-meter peaks are found in Karakoram mountain range than anywhere else on Earth.
Shisha Pangma is the youngest and smallest of the eight-thousanders. It's also the only one located entirely in Tibet.
Found on the border of China and Pakistan, Gasherbrum II (8,034 meters (26,358 feet), the 13th highest mountain on the planet, was first summited by an Austrian team in 1956. According to the Earth Observatory site, it's one of the easiest on our list to climb, and mountaineers "have skied, snowboarded, parachuted, and even hang-glided down from the summit."
Found on the border of Pakistan and China, Broad Peak, sometimes called K3, is the 12th-highest mountain on our list at 8,047 meters (26,400 feet).
Gasherbrum I, also called Hidden Peak, is the 11th-tallest mountain in the world and is just 46 meters taller than Gasherbrum II. It's part of the Gasherbreum massif in the Himalayan Karakoram range. Gasherbrum means "beautiful mountain" in Balti, a Tibetan language.
Annapurna is just the 10th-tallest of the eight-thousand meter peaks -- 8,091 meters (26,545 feet) -- but it's considered the most deadly for climbers, with a fatality rate of 32 percent.
Nanga Parbat -- “naked mountain” in Urdu -- is the ninth-tallest mountain in the world at 8,126 meters (26,660 feet). It's known as a perilous climb, and though it's been tried, no team has ever summited Nanga Parbat in winter.
Manaslu has a sharp rock peak that can only host a few climbers at a time. It's the eighth-tallest mountain in the world at 8,156 meters (26,759 feet).
Dhaulagiri in Nepal is 8,167 meters (26,795 feet) making it the seventh-highest mountain in the world. Its twin peaks are separated by the largest gorge in the world.
Cho Oyu on the Tibet-Nepal border rises to 8,201 meters (26,906 feet). It's the sixth-highest peak in the world. Some consider it the safest to climb, with a low avalanche risk. Only Everest has been summited more often.
Makalu at No. 5 is shaped like a four-sided pyramid and its peak rises 8,463 meters (27,766 feet) above sea level.
Lhotse in China is connected to Everest by the South Col. It's the fourth-highest eight-thousander at 8,463 meters (27,766 feet).
The third highest mountain in the world, Kangchenjunga, is found on the border between Nepal and India. It was actually thought to be the tallest in the world until an accurate survey was made in 1849 and discovered that Everest was top dog.
K2, the world's second tallest mountain -- 8,611 meters (28,251 ft) -- was the second peak surveyors came while exploring the Karakoram Range, so they called it K2 and the name stuck. K2 is notoriously difficult to climb and is just a few hundred meters short of Everest.
This photo of Mount Everest -- 8,848 meters (29,029 feet) -- was captured by the Expedition 26 crew in 2011, looking nearly straight down from the International Space Station.
Using the northeast ridge route, climbers move along the East Rongbuk Glacier (lower left), camp at the base of the Changtse mountain, move up the North Col, and pass a series of camps on on the North Face, then push to the summit.
