STELLAR CLASSIFICATIONS: TYPE “O” STARS
... The one biggest plus to “M” class stars is that they live a very long time. 56 billion years on average. With lifespans more than 5 times that of the sun, there’s plenty of time for life to evolve around a star such as this. Color: These stars appear orange-red in the visible spectrum, but emit most ...

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.
