Windows to the Galaxy
The galactic center is totally obscured in the visual
part of the spectrum by the dense dust clouds. Except
for a few "windows" (see below), this dust prevents us
from seeing more than a few thousand parsecs in any
direction in the galactic plane. The dust tends to
clump in clouds associated with the spiral arms (see
section on Spiral Arms). The most famous window
through which we can look to greater distances than
average is in the direction of the globular cluster NGC
6522. The most transparent or homogeneous window
in the galactic equator is toward Puppis, between
galactic longitudes 240°-250° (245° optimum view).
Dust particles are not the only form of obscuring
matter in interstellar space. Many kinds of gas
pervade the space between the stars. The most
abundant gas, Hydrogen, was discovered in the
1950s, when its emission at a radio wavelength of 21
