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 16O-poor primordial dust. • Freshly-synthesized dust relatively rich in 17O and 18O may have been added to the molecular cloud in which the Sun formed.
