Shells of ancient supernovas [ http://antwrp.gsfc.nasa.gov/apod/supernova_remnants.html ], cocoons surrounding newborn stars [ http://antwrp.gsfc.nasa.gov/apod/ap961017.html ], and specks from distant quasars [ http://antwrp.gsfc.nasa.gov/apod/ap981211.html ] highlight this tremendous vista toward the constellation [ http://www.astro.wisc.edu/~dolan/constellations/extra/constellations.html ] of Cygnus [ http://www.astronomical.org/constellations/cyg.html ]. The representative color image [ http://www.ras.ucalgary.ca/CGPS/gallery/vistas/cygnus/ ] covers about 10 degrees across on the sky but is only a small part of the Canadian Galactic Plane Survey [ http://www.ras.ucalgary.ca/CGPS/ ] in radio light [ http://www.qrg.ils.nwu.edu/projects/vss/docs/Communications/2-more-about-radio-waves.html ]. Diffuse bands of ionized [ http://csep10.phys.utk.edu/astr162/lect/light/ionization.html ] gas flow though a dominating region of star formation [ http://archive.ncsa.uiuc.edu/Cyberia/Bima/StarForm.html ], located about 6000 light-years [ http://chandra.harvard.edu/photo/cosmic_distance.html ] away. Two prominent supernova shells [ http://antwrp.gsfc.nasa.gov/apod/ap990913.html ] visible include the brown globule [ http://www.ras.ucalgary.ca/CGPS/gallery/vistas/cygnus/cygnusdetails.html ] on the lower left and the white bumpy sphere [ http://www.ras.ucalgary.ca/CGPS/gallery/vistas/cygnus/cygnusdetails.html ] on the upper right. To the left of the brown globule is the entire North America Nebula [ http://antwrp.gsfc.nasa.gov/apod/ap000501.html ]. Prominent stellar cocoons [ http://antwrp.gsfc.nasa.gov/apod/ap010805.html ] are visible throughout the image as bright white knots. Some of these stars will likely generate future supernova shell [ http://antwrp.gsfc.nasa.gov/apod/ap010325.html ]s. Far in the distance, visible here as only red dots, quasars [ http://imagine.gsfc.nasa.gov/docs/ask_astro/quasar.html ] glow.
