Elias 2-27 Dust and 13CO and C18O emissions composite image

Multiple molecular tracers helped scientists to better understand the gases present in the disk surrounding Elias 2-27. Visible in this composite are the 0.87mm dust continuum data (blue), C18O emission (yellow), and 13CO emission (red). Credit: Teresa Paneque-Carreño/ Bill Saxton, NRAO/AUI/NSF
