Abstract
We discuss the measurements of deuterium abundances in high redshift quasar absorbers, in the solar system and in the interstellar medium. We present new results that indicate spatial variations of the deuterium abundance in the interstellar medium at the level of similar to 50% over scales possibly as small as similar to 10 pc, and discuss plausible causes for the origin of these variations.
