HOW TO USE THIS MAP
This map portrays the sky as seen
near 35° north latitude. Located
inside the border are the cardinal
directions and their intermediate
points. To find stars, hold the map
overhead and orient it so one of
the labels matches the direction
you’re facing. The stars above
the map’s horizon now match
what’s in the sky.

The all-sky map shows
how the sky looks at:
midnight May 1
11 P.M. May 15
10 P.M. May 31
Planets are shown
at midmonth

STAR COLORS
A star’s color depends
on its surface temperature.

-^ The hottest stars shine blue



  • Slightly cooler stars appear white

  • Intermediate stars (like the Sun) glow yellow

  • Lower-temperature stars appear orange

  • The coolest stars glow red

  • Fainter stars can’t excite our eyes’ color
    receptors, so they appear white unless you
    use optical aid to gather more light
