Explanation:
Whatever became of
Comet Hale-Bopp?
The brightest
comet in recent years has continued into the outer
Solar System and is now further from the
Sun than
Saturn.
To the surprise of many,
Comet Hale-Bopp is still active,
continuing to spew gas, ice and
dust particles out into space.
Pictured above earlier this month,
Comet Hale-Bopp
can be seen in the
Southern Hemisphere
with a moderate sized-telescope.
The continued activity of
Comet Hale-Bopp
may be due to the large size of its
nucleus - estimated to be about 50 kilometers across.
The unusual dotted appearance of most stars in the
above image
is due to the 14 discrete exposures that were centered on the
comet and not the stars.
