Few objects in the sky have more magnetic personalities than planetary nebulas.    Astronomers have been drawn to the strange objects since early telescopes in    the 1700s revealed them as fuzzy patches of light that resembled the giant planets    of our outer solar system.

Astronomers using NASA's Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.

The Cassini spacecraft's mission to Saturn has revealed a new radiation belt around the ringed planet and found that lightning in its atmosphere is occurring in different patterns than it did when NASA's Voyagers flew by in the early 1980s, scientists said.

People have long gazed at the sky and wondered if there were other worlds&#x2014;Earths&#x2014;in orbit around the distant stars.  Since the 1992 announcement of pulsar planets by Alex Wolszczan, more than 130 giant (Jupiter and Saturn size) planets in orbit about nearby stars have been discovered using ground-based telescopes. In 2007, NASA's Kepler Mission will begin the space-based search for extrasolar planets. Over its planned observing lifetime, Kepler is likely to discover many hundreds of extrasolar planets both large and small. ...
