A shekara ta 2001, lura a X-ray wavelengths da Chandra X-ray Observatory ya bayyana kasancewar gas mai zafi sosai a cikin NGC 6543 tare da zafin jiki na 1.7 × 106 K. Ana tunanin cewa gas mai zafi yana haifar da mummunan hulɗar iska mai sauri tare da kayan da aka fitar a baya. Wannan hulɗar ta ɓoye kumfa na ciki na nebula. Chandra lura sun kuma bayyana tushen tushe a matsayin tauraron tsakiya. Hasken wannan tushe ya faɗaɗa zuwa ɓangaren ɓangaren X-ray, zuwa 0.51.0 keV. Tauraruwar da ke da yawan zafin jiki na hotuna na kimanin 100000 K ba za a yi tsammani ya fitar da karfi a cikin X-ray mai tsanani ba, don haka kasancewarsu wani abu ne na iska mai ban mamaki.
tashin hankali na iska mai sauri tare da kayan da aka fitar da shi a baya
