... Colors of Stars Astronomers measure the brightness of stars at three colors of light: The "U" band at 360 nm The "B" band at 440 nm The "V" band at 540 nm The "color index" of a star is defined as the magnitude in the B filter, minus the magnitude in the V filter. Color Index = B-V, where B an ...

Aquarius (constellation)
Aquarius is a constellation of the zodiac, situated between Capricornus and Pisces. Its name is Latin for ""water-carrier"" or ""cup-carrier"", and its symbol is 20px (Unicode ♒), a representation of water.Aquarius is one of the oldest of the recognized constellations along the zodiac (the sun's apparent path). It was one of the 48 constellations listed by the 2nd century AD astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river.
