STAR COLORS:
Stars’ true colors
depend on surface
temperature. Hot
stars glow blue;
slightly 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.
