What happens when you look up into the night sky?

When you look up into the night sky, an immense amount of scientific wonder waits to greet you. The colossal nebulae of gas and dust, alight with the fires of star formation; the swirling mass of planet-sized atmospheric storms on gas-giants both near and far; or even the beautiful but fearsome steps of stellar life-cycles, producing nuclear-powered gaseous orbs capable of warming an entire planet in life, and vaporizing an entire solar system in death.# N#There is so much there to captivate, and much of it only a personal telescope away from observing. And yet, with all we know about the world beyond those small points of light in the void, it is hard to escape natural inclinations when studying space. After all, to draw lines between points, or imagine images and stories in the place of these vacant expanses, is perhaps one of the oldest human endeavors. That being said, of all those ancient pictures in Western culture, at least—the Big Dipper and Ursa Major are probably among the most recognizable.

In Ireland and the United Kingdom, it has often been identified as a plow—while in German, Slavic, and even Hungarian traditions, it has been associated with a large wagon.#N#Though Ursa Major’s identity as a bear is relatively uncontested, the Big Dipper’s status as an asterism leaves it much more open to interpretation.
