Summary

Description

A "God's view" map of Milky Way as seen from far Galactic North (in Coma Berenices). The yellow dot represents the position of Sun. The spiral arms are colored differently in order to highlight what structure belongs to which arm. H II regions are marked as dots colored in the same color as their spiral arm. They come in three sizes, measured by the excitation parameter U:

  1. small - U > 200 pc cm−2
  2. medium - 200 > U > 110 pc cm−2
  3. large - 110 > U > 70 pc cm−2
