1.mm/submm photons are the most abundant photons in the spectrum of most spiral galaxies – 40% of the Milky Way Galaxy

2.After the 3K cosmic background radiation, mm/submm photons carry most of the energy in the Universe

3.Unique science can be done at mm/sub-mm wavelengths because of the sensitivity to thermal emission from dust and molecular lines

4.Probe of cool gas and dust in:
I. Proto-planetary disks
II. Star formation in our Galaxy
III.Star formation at high-redshift
