Explanation:
Comet Garradd continues to brighten as it drifts across the northern sky.
Last week the comet, visible with binoculars and discernable by its
green coma,
passed nearly in front of globular cluster M71.
M71 was once thought to be
an open cluster, but is now known to be an older
globular cluster
containing over 10,000 stars.
The photogenic duo was captured with a standard digital camera in a 10-minute, wide-angle
exposure toward the northern constellation of the Arrow (Sagitta).
The stars
Sham (Alpha Sagittae),
Beta Sagittae,
Gamma Sagittae, and
the
double star
Delta Sagitta are
all visible in a
diagonal band running down from the upper left.
Comet C/2009 P1 (Garradd), will
remain visible in northern skies for months and will reach its closest approach
to the Sun in December.
