... A) The circle of light will spread out more, and more area means less concentration of light. This can also be demonstrated with a circle drawn on small balloon and then inflated further. c) You have two flashlights, with different luminosities. How can you make them appear equally bright? The brigh ...

... When stars first form out of interstellar gas, they have radii substantially larger than main sequence stars of the same mass. As a result, their centres are too cool to drive nuclear reactions, and they are not in energy equilibrium. They therefore contract over a KelvinHelmholtz timescale. As they ...

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.
