3. http://www.psrd.hawaii.edu/Aug10/gas-dust-Oisotopes.html New View of Gas and Dust in the Solar Nebula Refractory inclusions (left) condensed from gas of solar composition with O- isotopes similar to the Sun (see Genesis data point). FUN inclusions (right) represent equilibration between solar gas and 16 O- poor primordial dust. Freshly-synthesized dust relatively rich in 17 O and 18 O may have been added to the molecular cloud in which the Sun formed.
