Explanation:
Is the only thing unusual about this nebula its shape? Pictured above is
the IC 2220 - the Toby Jug Nebula - a
reflection nebula surrounding a
normal
red giant
star.
Reflection nebulae shine by light reflected from
the central star(s). This nebula appears to have been created from the
current phase of mass-loss from the central star. Normal
gas and
dust
compose the nebula. The nebula's peculiar but photogenic
"bi-polar,
bi-conical" shape, however, continue to make it a popular object of study.
