What are dark energy and dark matter?
How and when did galaxies first assemble?
How universal are the processes of star formation in galaxies?
How do stars evolve, and what is their distribution of masses?
How does star-formation and planetary disk formation depend on environmental conditions?
What is the composition of planets, comets, and minor planets in our Solar System (and beyond)?

What is the large-scale structure of matter in the Universe?
How did galaxies form out of the intergalactic medium?
What types of galactic halos and outflowing winds do star-forming galaxies produce?
How were the chemical elements for life created in massive stars and supernovae?
How do stars and planetary systems form from dust grains in molecular clouds?
What is the composition of planetary atmospheres and comets in our Solar System (and beyond)?
COS Spectroscopy of the Cosmic Web
COS will greatly increase the number of quasar sight lines explored by Hubble.
In just a few days, COS can sample as much of the Universe as all existing STIS observations of quasars have probed!
