Comet
Holmes, discovered by English amateur astronomer Edwin
Holmes in November 1892, was making a quiet return to the inner solar
system
until October 24, 2007.
A dramatic eruption occurred, sending out vast amounts of dust and
gas
from the icy nucleus. The comet increased from approximately 18
to 2.5
magnitude; a factor of about one million! The nucleus is hidden
deep
within the star-like point in the center of the fuzzy coma seen
here.
Below and to the right of the nucleus is a fan-shaped feature -
possibly a jet
emanating from the comet's surface. At the time, the comet was
located
between the orbits of Mars and Jupiter so no tail was visible. |
