WONDERS OF THE UNIVERSE
How many of the images in the following slides can you identify?
Saturn
Mars
Neptune
Mercury
Earth from space
Shadow of moon on earth
Global radar view of the surface of Venus from Magellan radar imaging between 1990–1994
Jupiter
Uranus
Europa (one of Jupiter’s moons)
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
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)
Io (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.

Halley's Comet, is the best-known 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.
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.
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
