“In 1963 astronomers were astounded to discover that certain faint, star-like objects have very large redshifts. The large redshifts imply that these objects, now known as quasars (QUASi-stellAR objects), lie near the edge of the observable Universe. To be visible at such extreme distances of billions of light years, they must emit tremendous amounts of energy. Where does the energy come from? In the most widely accepted model, a quasar is the bright nucleus of an active galaxy powered by a central, supermassive black hole."

“Pictured above is a total solar eclipse, with the Sun's corona, clearly visible surrounding the Moon. This picture is a composite of differently exposed photos of an eclipse that occurred on July 11, 1991. Today there will be another total eclipse of the Sun, the last until March 1997. The path of today's total eclipse will begin in the Middle East, move though southern China, and end in the Pacific Ocean south of the Marshall Islands. Those only near the path will see a partial solar eclipse. NASA keeps detailed maps of the predicted path of the eclipse."

“Orson Welles became an instant legend on Halloween in 1938 for his radio dramatization of H.G. Wells' "War of the Worlds". Some listeners who did not realize it was a theatrical production were driven to near panic by this fictional account of invaders from Mars. In the story, as in the above Hubble Space Telescope image, Mars was at "opposition", its point of closest approach to the Earth, a distance of some 65 million miles. For the Martians, it was imagined that this was a good time to invade. For astronomers, opposition is a good time to study the red planet and this HST image, represents the clearest view of Mars ever for an Earth telescope. The icy north polar cap is visible at the top of the picture as well as a veil of white clouds along the planet's left edge. The dark markings represent areas where the reddish tinged dust characteristic of the surface has been blown away by the Martian winds."
