... The human eye has a “retina” to sense the presence of light. The retina has “rods” to sense the amount of “visible” light and “cones” to sense particular color (blue, green, red). If you have excellent color vision and light sensitivity, you may be able to see that the stars Betelgeuse and Rigel in ...

In fact, their lower limit in practice will normally be much larger, since a collapsing star will stop at the white dwarf stage if its mass is less than the Chandrasekh ...

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.
