BSL Astronomy Glossary - vega - definition

Definition: Vega is the brightest star in the constellation of Lyra, the harp. It is one of the three bright stars that make up the star pattern, the Summer Triangle. The Summer Triangle is easily located in southern skies during the summer months and each of the three bright stars that make up this star pattern belongs to a different constellation: the star Altair in the constellation of Aquila, the star Deneb in the constellation of Cygnus and, thirdly, Vega in the constellation of Lyra. When the artist’s impressions are added in the video, Vega can be seen lying at the head of the harp.
