Find Vega and the Summer Triangle
Vega is the brightest star in Lyra, the Lyre. On clear northern summer evenings look for a brilliant, blue-white star high in the sky. Together with Deneb in Cygnus and Altair in Aquila it forms the Summer Triangle, a recognisable pattern spanning three constellations.
A former pole star
Earth’s rotation axis changes direction slowly over thousands of years. As a result, the northern celestial pole does not always point toward the same star. Long before Polaris held its present role, Vega lay much nearer the pole and served as a northern pole star.
Why astronomers study it
Vega has played an important role in the history of stellar photometry, the measurement of a star’s brightness. It has also been studied for the material around it. The star’s brightness and location make it useful to observers learning to compare objects in the sky.
Enjoy the view
You do not need a telescope to see Vega. Choose a dark, safe location away from direct glare, let your eyes adjust, and use a current star chart for your location. Visibility depends on weather, season, latitude and light pollution.
