Radio: Yesterday’s Episode

Stargazing

  • Moon and Saturn

    The gibbous Moon rolls across the southern sky tonight. The planet Saturn, which looks like a bright star, is to the left of the Moon at nightfall. Saturn will be closer to the upper right of the Moon tomorrow evening.


  • Grus

    Grus, the crane, moves low across the south on October evenings. The star that marks the crane’s head, Gamma Gruis, is visible from most of the U.S. Tonight it stands due south about 10 p.m., below the Moon. The farther south you are, the higher the star stands.


  • Pisces

    Pisces, the fishes, which is one of the constellations of the zodiac, is in the eastern sky at nightfall. It is faint, though, so you need a dark sky to see it. It stands to the left of the bright planet Saturn.


Moon Phases

At the new Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated (position 1 in illustration). In other words, the Moon is between Earth and Sun. At first quarter, the half-lit Moon is highest in the sky at sunset, then sets about six hours later (3). At full Moon, the Moon is behind Earth in space with respect to the Sun. As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).
