Mars and Saturn Shine Brilliantly in the Eastern Heavens during October THE TWO planets swing well into view during this month. They can be seen almost exactly due east and a trifle to the north at the times indicated for observation. Mars is unmistakable; its brilliance and reddish color make it a distinc tive object in the sky. The constellation Pegasus, the Winged Horse, (page 109) flies upside down in the southern sky just below the zenith. Beneath Pegasus lies the great area known as the "heavenly sea" (p. 110). It extends from Capricornus (the Sea Goat) on the west, to Eridanus, the Heavenly River, on the east. The most conspicuous star in all this region is Fomalhaut, in the constellation Piscis Austrinus (the Southern Fish). It is used by navigators, and its brilliance is all the more enhanced by the fact that this section of the sky does not contain many bright stars. The Milky Way revolves around Polaris as do the,constellations. This accounts for its changing position on the charts from month to month; sometimes the Milky Way passes diagonally through the center of the hourglass, at other times it is divided between the two halves. The October sky map also shows the appear ance of the heavens in the early morning of July 15 at 4:30 a.m.; July 30, 3:30 a.m.; August 15, 2:30 a.m .
