Doha was founded in the 1820s as an offshoot of Al Bidda. It was officially declared as the nation's capital in 1971, when Qatar gained independence from being a British Protectorate. As the commercial capital of Qatar and one of the emergent financial centers in the Middle East, Doha is considered a beta-level global city by the Globalization and World Cities Research Network. Doha accommodates Education City, an area dedicated to education and research; Hamad Medical City, an Hamad Medical Corporation administrative area of medical care which includes Hamad General Hospital, Heart Hospital, Women's Wellness and Research Center and Qatar Rehabilitation Institute as well as a number of specialty clinics and support infrastructure.

Vega is the brightest star in the northern constellation of Lyra. It has the Bayer designation α Lyrae, which is Latinised to Alpha Lyrae and abbreviated Alpha Lyr or α Lyr. This star is relatively close at only 25 light-years from the Sun, and, together with Arcturus and Sirius, one of the most luminous stars in the Sun's neighborhood. It is the fifth-brightest star in the night sky, and the second-brightest star in the northern celestial hemisphere, after Arcturus.
Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the Sun". Vega was the northern pole star around 12,000 BC and will be so again around the year 13,727, when its declination will be +86° 14′. Vega was the first star other than the Sun to be photographed and the first to have its spectrum recorded. It was one of the first stars whose distance was estimated through parallax measurements. Vega has functioned as the baseline for calibrating the photometric brightness scale and was one of the stars used to define the zero point for the UBV photometric system.
