...located by its radio waves, then confirmed visually at the Kitt Peak National Observatory near Tucson, appearing as a faint, fuzzy object. A computer-enhanced photograph shows the galaxy as a brightly colored, amoeba-shaped mass. Next, the scientists determined the distance of the galaxy by taking an optical spectrum that revealed what one team member, Kenneth Chambers of Johns Hopkins University, calls cosmic fingerprints -- emission lines with sharp features characteristic of hydrogen and carbon. In distant galaxies, these lines occur at much redder wavelengths than those emitted by the same elements on earth; this so-called red shift, believed...
Because the suspected planets are lost in the glare of the stars they orbit, they could not actually be seen. Instead, the astronomers analyzed the shifts of light in the spectrum associated with a star as it moves. A shift toward red means the source is moving away from the observer, toward blue that it is moving toward him. By carefully measuring these color shifts, astronomers detected a characteristic wobble in the motion of the stars that could be caused by the gravitational pull of a nearby orbiting body...
...broad spectrum of scholars see no compelling intellectual reason to reject large portions of the Gospels, and find new inspiration in the lessons of Jewish studies and archaeology. For them, no single image of Jesus will do. These thinkers see Jesus as both apocalyptic prophet and reforming sage, as purifier of Judaism and builder of a new order. Advocates range from hard-line Fundamentalists and moderate Evangelicals, who all along have deemed the Gospels historically trustworthy, to moderate liberals who use higher criticism but have become skeptical about skepticism...
...other end of the political spectrum is Carlos Morton, 40, a didactic, polemical, yet often fiercely funny Texan. Born in Chicago, Morton spoke only Spanish until age five, then adopted English. Frequently uprooted to such places as Panama and Ecuador because his father was a career military man, he now teaches at Laredo Junior College, a few blocks from the Mexican border...
