Explanation:
Comet Lovejoy, C/2014 Q2, is framed like a cosmic Christmas tree
with starry decorations in this colorful telescopic portrait, snapped
on December 16th.
Its lovely coma is tinted
green by diatomic C2 gas fluorescing in
sunlight.
Discovered in August of this year,
this
Comet Lovejoy is currently
sweeping north through the constellation Columba, heading for Lepus
south of Orion and bright enough to offer
good binocular
views.
Not its first time through the inner Solar System, this Comet Lovejoy
will pass closest to planet Earth on January 7, while
its perihelion (closest point to the Sun) will be on January 30.
Of course, planet Earth's own 2015 perihelion passage is scheduled for
January 4.
A
long period comet,
this Comet Lovejoy should return again ... in
about 8,000 years.
