"We should hardly be willing to bind ourselves to
a program which exacted so much routine work for so long."
E. S. Holden, commenting on the possibility of astronomers at Lick
observatory engaging in the Carte du Ciel project
These images, as well as those on the
following page, are products of the new astronomy. Note how different
they are from the conception of astronomy represented by the Carte
du Ciel project, both in substance and variety. For example, the image
on the right is a set of spectra taken from a star. The ability to
record astral spectra gave the new astronomers the opportunity to
learn the elements of which the star consisted.
