Vega

Brightest star in the constellation Lyra and the fifth-brightest star in the night sky. It is a blue-white star, about 25 light years from the Sun, with a true luminosity 50 times that of the Sun.

In 1983 the Infrared Astronomy Satellite (IRAS) discovered a ring of dust around Vega, possibly a disc from which a planetary system is forming.

As a result of precession (the slow wobble of the Earth on its axis), Vega will become the north polar star about AD 14,000. The name Vega is from Arabic indicating the eagle depicted as carrying the lyre. First-magnitude Vega was the first star to be photographed (Bond and Whipple, 1850) and to have its spectrum recorded photographically (Draper, 1872).
