Radio: Yesterday’s Episode


  • Moon and Saturn

    Saturn stands near the Moon the next few mornings. The Sun’s second-largest planet looks like a bright star. It will stand well to the left of the Moon at dawn tomorrow, but much closer to the Moon on Thursday.

  • Morning Planets

    Three planets are in view at dawn. Saturn is half way up the southeastern sky and looks like a bright golden star. Mars is due east and shines just as brightly as Saturn. Brilliant Jupiter stands to the lower left of Mars.

  • Tarazed

    Altair, the brightest star of the eagle, is one of the 12 brightest stars in the night sky. But Tarazed, a fainter star that appears just above it as night falls, is actually about 200 times brighter. It looks fainter only because it’s about 35 times farther away.

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).
