Saturn
Seen from
Near and
Far
As
Saturn
grows
closer
through
the eyes
of the
Cassini
spacecraft,
set for a
July 1
arrival,
both
Cassini
and the
Earth-orbiting
Hubble
Space
Telescope
snapped
spectacular
pictures
of the
planet and
its
magnificent
rings. For
the first
time,
astronomers
can
compare
views of
equal-sharpness
of Saturn
from two
very
different
perspectives.
The view
from
Hubble,
top, taken
on March
22, 2004,
is so
sharp that
many
individual
Saturnian
ringlets
can be
seen. When
Cassini
returned
its
picture of
Saturn,
bottom, on
May 16, it
was so
close to
the planet
that the
camera
could not
fit the
whole
planet in
its
field-of-view.
Cassini is
still
about 12.4
million
miles away
and only
36 days
from
reaching
Saturn.
The
differences
between
the Hubble
and
Cassini
images are
mainly due
to the
different
sets of
filters
used. |
