This undated image released by Bob Goldstein and Vicki Madden taken with an electron microscope, shows a micro-animal "tardigrade" also known as a water bear, at the UNC in Chapel Hill, N.C. In Jan. 2015, scientists found the DNA of a tardigrade in Antarctica's Lake Vostok, located in an area considered the most remote place on Earth. The mostly freshwater lake is buried under miles of ice, and hasn’t been near open air for 15 million years, exciting astronomers who search for possible forms of life on other planets.
