Radio: Yesterday’s Episode

Stargazing

  • Deneb

    Deneb, the bright star that marks the tail of the swan, is far bigger, heavier, and brighter than the Sun. It stands a third of the way up the northeastern sky at nightfall, at the left end of the “cross” that outlines the swan’s body and wings.


  • Full Moon

    The Moon is full today at 6:56 p.m. CDT. The full Moon of June is known as the Flower Moon, Strawberry Moon, Rose Moon, or Honey Moon. It’s also called the Short-Night Moon, because it is in view for less time than any other full Moon of the year.


  • Tarazed

    Tarazed, the second-brightest star of Aquila, the eagle, is a small fraction the age of the Sun, but because it’s more massive it has puffed up to become a red giant. It is low in the east at nightfall, close above brighter Altair.


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).

From Canals to Poppy Seeds and Leopard Spots

by Damond Benningfield

Twin Viking landers touched down on Mars 50 years ago, and one of their experiments found evidence of life, which was quickly discounted.  But the debate continues, and we’ll review the Viking findings along with other claims of possible life on the Red Planet.  We’ll also tell you how planetariums are adapting to the ages of the Internet and social media.
