2. Star-forming regions: Orion region and others. Figure 6.10 illustrates an IR image
of the Orion Nebula, taken as the first-light image in December 1998 by IR
camera at the Cassegrain focus.
3. The Milky Way and the Local Group: The structure of our Galaxy, Andromeda
Galaxy, and the associated dozens of dwarf galaxies are observed, along with the
activities of their nuclei.
4. Realm of galaxies: the diversity of galaxies in shapes and sizes, active galaxies
and active nuclei of galaxies, dynamical structure of colliding galaxies and
mergers.
5. Distant galaxies with high redshift z making use of Subaru prime focus camera
(Supreme-Cam) and spectrograph (FMOS).
Figure 6.11 demonstrates the most distant galaxy (red object in enlarged picture)
in October 2007. The redshift of this galaxy is z ¼ 7, which means it lies about
13 billion light-years away.
