Explanation:
It's rare that such different objects are imaged so
close
together.
Such an occasion is
occurring now, though, and was
captured two days ago in combined parallel exposures from the
Canary Islands of
Spain.
On the lower right, surrounded by a
green coma and emanating an unusually
split blue ion tail
diagonally across the frame, is
Comet C/2013 X1 (PanSTARRS).
This giant snowball has been
falling toward our Sun
and brightening since its discovery in 2013.
Although
Comet PannSTARRS is a picturesque target for long-duration exposures of astrophotography,
it is expected to be only barely
visible to the
unaided
eye when it reaches its
peak brightness in the next month.
On the upper left, surrounded by
red-glowing gas, is the also-picturesque
Helix Nebula.
At 700
light
years distant,
the Helix is not only much further away than the comet,
but is expected to retain its appearance for thousands of years.
