Explanation:
Vega is a bright blue star 25 light years away. Vega is the brightest star in the Summer Triangle, a group of stars easily visible
summer evenings in the northern hemisphere. The name
Vega derives from Arabic origins, and means "stone eagle."
4,000 years ago, however, Vega
was known by some as "Ma'at" -
one example of ancient human
astronomical knowledge and language. 14,000 years ago, Vega, not
Polaris, was the
north star. Vega is the fifth brightest star in the night sky, and has a diameter
almost three times that of our Sun.
Life
bearing planets, rich in liquid water,
could possibly exist around Vega. The
above picture,
taken in January, finds Vega, the
Summer Triangle, and
Comet Hale-Bopp high above
Victoria,
British Columbia, Canada.
