Radio: Yesterday’s Episode

Stargazing

  • Sagittarius

    In mythology, Sagittarius was a centaur holding a bow and arrow. To modern eyes, though, the constellation looks like a teapot. It is low in the south-southeast at nightfall, with the handle to the left and the spout to the right.


  • Moon and Saturn

    The fat gibbous Moon creeps up on the planet Saturn tonight. Saturn is to the lower left of the Moon as they climb into good view, before midnight. The planet looks like a bright star.


  • Double Double

    Epsilon Lyrae, a famous double-double star system, stands high in the east as darkness falls this month, in Lyra, the harp. If you have sharp eyesight, you might see Epsilon Lyrae as two stars. A telescope reveals four stars, which form two pairs.


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).
