Glenn Chaple's observing basics: A ring and a triangle
August 2004: It's time for another edition of Professor Chaple's pop multiple-choice astroquiz.
Greetings all you seekers of astronomical knowledge. It's time for another edition of Professor Chaple's pop multiple-choice astroquiz: Is a triangle a three-sided geometric figure? A musical percussion instrument? Or, is a triangle Vega, Altair, and Deneb? If you answered "yes" to either of the first two, you're wrong — at least from an astronomical viewpoint. "Vega, Altair, and Deneb" is the right answer. These three bright stars make up the Summer Triangle, which currently is visible in the evening sky. Traversed by the Milky Way, the Summer Triangle is rich with telescopic treats, some of which are easy targets for the beginner.
