Shadow of moon on earth
Earth from space
Global radar view of the surface of Venus from
Magellan radar imaging between 1990–1994
Jupiter
Uranus
Enhanced-color view of part of Conamara
Chaos, showing ice rafts up to 10 km (6
mi) across. White areas are ejecta from
the crater Pwyll
Europa (one of Jupiter’s moons)
Craggy, 250 m high peaks and smooth
plates are jumbled together in a close-up
of Conamara Chaos
The craters Gula and
Achelous (bottom), in the
grooved terrain of Ganymede,
with ejecta "pedestals" and
ramparts.
Ganymede (one of Jupiter’s moons)
The detection of very high
temperature volcanism--hotter than
any terrestrial lavas currently
erupting--is one of the most
spectacular discoveries by the
Galileo mission at Io. The images
show curtains of lava fountains
erupting on the surface. They were
taken by the Galileo spacecraft on
11/26/99. The active region is
approximately 25 kilometers long
(15.5 miles) and 1 km (.6 mile) high.
Io (one of Jupiter’s moons)

plains, illustrating the

Halley's Comet,
is the bestknown of the
short-period
comets and is
visible from
Earth every 75–
76 years. Next
visit 2061.
Vesta, minor-planet designation 4 Vesta, is one of
the largest asteroids in the Solar System, with a
mean diameter of 525 kilometres.
Crab Nebula
In the constellation of
Taurus, a star is
exploding. The
explosion began with
a supernova almost a
thousand years ago,
and the resulting Crab
Nebula is continuing
to expand at more
than 1,000 km per
second. It is home to a
powerful pulsar.
OPTICAL
The Horsehead Nebula is a dark nebula in the constellation
Orion. The nebula is located just to the south of the star
Alnitak, which is farthest east on Orion's Belt, and is part of
the much larger Orion Molecular Cloud Complex.
Horsehead
The Orion Nebula is a diffuse nebula
situated south of Orion's Belt in the
constellation of Orion. It is one of the
brightest nebulae, and is visible to
the naked eye in the night sky.
The Cat's Eye Nebula (NGC 6543,
Caldwell 6) is a planetary nebula
in the constellation of Draco
