STAR COLORS:

Stars’ true colors

depend on surface

temperature. Hot

stars glow blue; slight-

ly cooler ones, white;

intermediate stars (like

the Sun), yellow; followed

by orange and, ulti mately, red.

Fainter stars can’t excite our eyes’

color receptors, and so appear white

without optical aid.

HOW TO USE THIS MAP: This map portrays

the sky as seen near 30° south latitude.

Located inside the border are the four

directions: north, south, east, and

west. To find stars, hold the map

overhead and orient it so a

direction label matches the

direction you’re facing.

The stars above the

map’s horizon now

match what’s

in the sky.
