Cat's Eye Nebula (Ngc 6543) Cats May Have Nine Lives, But This Star Only Has One And Here It Is Caught In Its Death Throes, Causing This Ejection Of Glowing Gases Into Outer Space Over A Thousand Years Ago.
A planetary nebula is the glowing gas ejected during the final stages of evolution of a star similar in mass to our sun. The cat’s eye nebula is expanding at a speed of 16.4 km/s. Ngc 6334 lies near the diffuse nebula ngc 6357, popularly known as the war and peace nebula, which also contains a.

To inform younger students about energy and environment, science, chemistry, english culture and english language, with accompanying images, interviews and videos. The cat’s eye nebula consists mainly of hydrogen and helium, with smaller quantities of heavier elements. The hst images seem to indicate that the central star is actually a binary system and that the nebula we see today is actually the result of at least two separate events.
