N'afọ 2001, nchọpụta na X-ray wavelengths site na Chandra X-ray Observatory kpughere ọnụnọ nke gas dị oke ọkụ n'ime NGC 6543 na okpomọkụ nke 1.7 × 106 K. A na-eche na gas na-ekpo ọkụ na-esite na mmeghachi omume siri ike nke ifufe kpakpando ngwa ngwa na ihe a na-achụpụ na mbụ. Mkparịta ụka a emeela ka ụfụfụ dị n'ime nke nebula ahụ. Chandra nchọpụta ekpughekwara isi ihe dị na ọnọdụ nke kpakpando etiti. Akụkụ nke isi iyi a na-agbatị na akụkụ siri ike nke X-ray spectrum, ruo 0.51.0 <unk> keV. A kpakpando na foto nke okpomọkụ nke ihe dị ka 100000 K agaghị atụ anya na ọ ga-esi ike na X-rays, ya mere ọnụnọ ha bụ ihe a na-atụ anya nke ifufe. Ọ nwere ike na-atụ aro ọnụnọ nke okpomọkụ dị elu n'ime diski accretion nke kpakpando anyanwụ.
