Look up at night during July and August in the northern mid-latitudes and almost directly overhead a really bright star is visible, that is Vega – brightest star in the constellation of Lyra.
Look 34 degrees to the Southeast from Vega and you will find Altair – brightest star in Aquila.
Look 38 degrees North of Altair and you will spot Deneb – the brightest star in Cygnus .
These 3 stars make up what is known as the Summer Triangle. It is visible in the eastern sky in the predawn hours of early Spring, almost the entire night in summer, and in the western sky in the early evenings of late Fall and early Winter.
Both Deneb and Vega were Pole Stars at one time due to Earth’s 26,000 year wobble also known as precession and both will be again, Deneb in the year 9800 CE and Vega in the year 14000 CE.
