Stargaze the Summer Triangle

 As the balmy season approaches, it's the perfect time to discuss the renowned Summer Triangle. Essentially, it's an asterism, a cluster of stars forming a geometric shape - in this instance, a triangle. The stars making up this triangle are Vega from the Lyra constellation, Deneb from the Swan constellation, and Altair from the Aquila constellation. This is often compared with its winter counterpart, composed of Betelgeuse from Orion, Procyon from Cane Minor, and Sirius from Cane Major. Let's delve into how to spot it.

As soon as the twilight fades following sunset, the Summer Triangle comes into clear view in the northeastern sky. Vega, the brightest star of the summer sky, is the first to appear. Shortly after, Deneb, the tail of the Swan, becomes noticeable further down on the left, while Altair almost simultaneously emerges on the right. With time, even in light-polluted skies, these three stars will progressively shine brighter, offering a mesmerizing display throughout July, August, and partially into September. Wishing you successful observations and clear skies.
