It all begins with the Summer Triangle, external, a bright three-cornered pattern of stars, called Vega, Deneb, and Altair.
The trio gets higher in the sky during the summer months and becomes more and more prominent.
They form what is known as an asterism or noticeable pattern of stars, created from three different constellations – Vega in the constellation Lyra the Harp, Deneb in Cygnus the Swan and Altair in the constellation Aquila the Eagle.
They are best seen rising in the east after sunset, forming a huge triangle overhead.
