A Tale of Comet Holmes


A beautiful blue ion tail
has become visible in deep telescopic images of
Comet Holmes.

Pointing generally away from the Sun and also planet Earth,
the comet's ion
is seriously
by our extreme viewing angle.

Still, enthusiastic comet watchers
have remarked that on the whole, the compact but tentacled appearance
suggests a jellyfish or even a cosmic

stunning view
of the comet's greenish coma and blue tail
was recorded on November 4 in clear skies near Budapest, Hungary.

The colors are caused by
molecules in
the tenuous gas, like C2 (green) and CO+ (blue),
fluorescing in sunlight.

In a more recent development,
the dramatic inset
is a deep image from L'Aquila, Italy on November 8,
showing the ion tail
disconnecting from the comet.
