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.
