The Cat's Eye Nebula
Explanation: Three thousand light-years away, a dying star throws off shells of glowing gas.
This image
from the
Hubble Space Telescope
reveals the
Cat's Eye Nebula
to be one of the most
complex
planetary nebulae
known.
In fact
, the features seen in the
Cat's Eye
are so complex that astronomers suspect the bright
central object
may actually be a
binary star system
. The term
planetary nebula
, used to describe this general class of objects, is misleading. Although these objects may appear round and planet-like in small telescopes,
high resolution images
reveal them to be
stars surrounded
by cocoons of gas blown off in the late stages of
stellar evolution
