The Big Dipper, which is near Polaris, or the North Star, is one of the easiest constellations to spot. O n a clear evening, the night sky is a brilliant spectacle—a breathtaking extravaganza of millions of stars and galaxies sparkling overhead. Luminous planets adorn the dark expanse with the rare glimpses of cosmic dust we fondly call shooting stars. Meanwhile, the moon remains a shining centerpiece that hangs in the sky as earthbound observers watch its grand progression from new moon to full each month. at the cosmos. With origins in mythological and religious beliefs, astronomy is the oldest natural science. Early astronomers such as Aristotle, Ptolemy, Copernicus, and Galileo that make up our universe. The vikings looked to the angle of the North Star to help them determine their latitude. National interest in all that lies beyond Earth’s atmosphere rose in the years that followed World War II, when the United States man on the moon. The fascination seemed to fade over the years, but, in recent years, eyes are again turning toward the skies. A Lost Art Perhaps television, computers, video games, and other techno gadgets were simply more alluring than the moon, stars and planets. Or perhaps the increasing glare of modernday cityscapes and streetlights—“light Earth’s celestial neighbors from urban environments—is partly to blame for the dissipating interest. Today, we are in the midst of an astronomical renaissance, as more people become reacquainted and enamored with the nighttime sky. “I think there are a few reasons for the renewed interest in astronomy,” explains Dr. James Sowell, an astronomer who directs the campus observatory at Georgia Institute of Technology and author of “The NakedEye Sky.” “In the last few years, there have been some interesting events in the sky: the large meteor that streaked across the sky in northern Russia and a couple of [exceptional] eclipses. And I think the prime-time television series, ‘Cosmos: A Spacetime Odyssey,’ got people interested again, too.” Whatever the reasons, people are once again captivated with space. Thousands have astronomy apps on their smartphones and tablets, and ventured into the night to spend quality time under the stars. If you and your family are somewhat intrigued by what’s out there, you’re in luck. The cooler temperatures and extended darkness of fall and winter Top: Jupiter; bottom: the moon combine to offer nearly perfect conditions for backyard—and beach-side—stargazing. Moonstruck ing up,” Sowell says. “I suggest they start by observing the moon and learning more about it—know its phases and understand how it orbits the Earth.” The moon completes its orbit in about 30 days and lunar phases are caused by the relative positions of the sun and moon in the sky. A new moon occurs when the moon lies between the sun and Earth. As the moon continues its orbit, more of it becomes illuminated and visible to our eyes. “The moon is visible with the naked eye, but the view through binoculars and telescopes is quite breathtaking; it never gets old,” Sowell says. “Through a lens, you can see the detail of thousands of craters.” Lunar maps and geologic atlases help stargazers identify the names of the many FALL/WINTER 2014/15 | SEA ISL AND LIFE 49 SI4_Star-e_v2-e.indd 49 9/19/14 9:51 AM
