A New Twist on an Old Nebula (2004)

2004 · Short film · 3 min

Synopsis

*Description*:> A Video News Release explains how the shapes of planetary nebulae are deceiving. Astronomers combined highly detailed images of the Helix Nebula from the Hubble Space Telescope's Advanced Camera for Surveys, with images from the Cerro Tololo Inter-American Observatory in Chile. From these observations, they were able to analyze the data and construct a 3-D model from measurements of the Helix Nebula using ground-based optical and radio telescopes to show the speed and direction of the outflows of material from the nebula. The team found surprises in their data that indicate that the Helix's structure is even more perplexing than originally thought. Technical facts about this news release: 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 690 light-years (213 parsecs) Dimensions: The image is roughly 287 arcminutes (5.6 light-years or 1.7 parsecs) across. About the Data Data Description: 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.
