| | ESA Science & Technology: Cat's Eye Nebula in Stunning Detail [heic0414] |
 | | Although the rings may be the key to explaining the final 'gasp' of the dying central star, the mystery behind the Cat's Eye Nebula's nested 'Russian doll' structure remains largely unsolved. |
 | | However, Romano Corradi (Isaac Newton Group of Telescopes, Spain) and collaborators, in a paper published in the European journal Astronomy and Astrophysics in April 2004, have instead shown that the formation of these rings is likely to be the rule rather than the exception. |
 | | The group of astronomers involved in the April 2004, Astronomy and Astrophysics paper are: R.L.M. Corradi (Isaac Newton Group of Telescopes, Spain), P. Sanchez-Blazquez (Universidad Complutense, Spain), G. Mellema (Foundation for Research in Astronomy, The Netherlands), C. Giammanco (Instituto de Astrofisica de Canarias, Spain) and H.E. Schwarz (Cerro Tololo Inter-American Observatory, Chile). |
