Have you ever wondered why the Summer Triangle that wonderful triad of the bright stars Vega, Deneb, and Altair is highest overhead during early evening at this time of year? I know, I know: you can see it in summertime. In early June, it clears the eastern horizon by 10:30 or so. Still, right now it's straight up as darkness falls, and it'll still be in view come early December.What I really like about the Summer Triangle is that it's such a springboard to other sky topics. For starters, the three stars themselves are incredibly interesting. Then the constellations they occupy are straightforward and easy to recognize. And finally they straddle the Milky Way, which I can just barely make out from my home.
I nibble on some of these topics in this month's Sky Tour Podcast. Enjoy!
