Looking for Life on Europa

At first glance Europa, Jupiter’s fourth largest moon, may not seem like the most likely place to find extraterrestrial life. The temperature is regularly -260 degrees Fahrenheit. Its surface is covered in a layer of ice several miles thick. And it is constantly being bombarded by fierce radiation. But National Geographic Emerging Explorer Kevin Hand is looking for alien life and he says this may be the place to find it. Europa has an enormous ocean, with more than twice the amount of liquid water found on earth. And when searching for life, Hand says it comes down to finding water. “Follow the water,” says Hand. “When it comes to life, that’s the keystone.”
