描述NGC 7293.jpg	Iridescent Glory of Nearby Helix Nebula. About the Object Object Name: Helix Nebula, NGC 7293 Object Description: Planetary Nebula Position (J2000): R.A. 22h 29m 48.20s Dec. -20° 49' 26.0" Constellation: Aquarius Distance: About 650 light-years (200 parsecs) Dimensions: The image is roughly 27 arcminutes (5.1 light-years or 1.6 parsecs) across. About the Data Data Description: Hubble data have been superimposed onto ground-based data taken by Travis Rector (NRAO) at the 0.9 meter telescope located on Kitt Peak, Tucson, AZ (NOAO/AURA/NSF). The HST data are from proposal 9700. Processed images may be obtained from the Helix MAST web site. The Hubble Helix Team includes M. Meixner, H.E. Bond, G. Chapman (STScI), Y.-H. Chu (U. Illinois, Urbana-Champaign), P. Cox (Institut d'Astrophysique Spatiale, France), W. Crothers, L.M. Frattare, R.Gilliland (STScI), M. Guerrero R. Gruendl (U. Illinois, Urbana-Champaign), F.
