Seen from the northern latitudes, the three brilliant stars of the Summer TriangleVega, Deneb and Altair – are actually out for at least part of the night every night of the year. Right now, the Summer Triangle shines in the eastern sky at and before dawn.

Around May Day, the Summer Triangle rises into the eastern sky by midnight, and when the June solstice comes rolling around, the Summer Triangle adorns the eastern sky at evening dusk. Because the Summer Triangle is out all night long during a Northern Hemisphere summer, this great big triangle of stars serves as a well-known fixture for the summer sky.

On a clear, dark night, the luminescent band of stars that we call the Milky Way passes right through signpost Summer Triangle.
