This Week’s Sky at a Glance, 2019 June 8 – 15 ~by Curt Nason

With turkey vultures becoming more prominent in the province, you might be interested in knowing a vulture once flew with the swan and the eagle in the sky. The bright star Vega can be seen high in the east in the late evening. Vega’s constellation is Lyra the Lyre or Harp, with the main part of the instrument being formed by a parallelogram of stars. If you point a telescope between the two brighter stars of the parallelogram, opposite Vega, you might notice a fat, blurry star. A moderate-sized telescope will show it as a smoke ring or doughnut. This is the Ring Nebula or M57, the remnants of a Sun-sized star that puffed off its layers of gas when it ran out of nuclear fuel. Near Vega is the star Epsilon Lyrae, a dimmer but naked-eye star that binoculars will show as two stars.

In mythology, the lyre was made from a tortoise shell by the Roman god Mercury, who gave it to Apollo. It was mastered by Apollo’s son Orpheus, who soothed all around him when he played. After his bride was killed tragically on their wedding night, he spurned the advances of the many young ladies vying for his attention. They schemed revenge, screaming loudly so as not to be affected by his music, and then beat him to death and tossed the lyre into the river. Zeus sent a vulture to retrieve the lyre and had it placed in the sky to commemorate Orpheus and his music. Star maps from a few centuries ago depicted the lyre in the talons of the vulture.
