Astronomy - February 2014

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.
