Ultra-violet measurements, like these, are important because ultra-violet rays from the sun occasionally interfere with earth's radio communications, and the energy from these invisible light waves supplies much of the solar heat that determines the earth's weather. Astronomers use slight, variations in the sun's ultra-violet spectrum as clues to the chemical and physical reactions goingon at various depths in the sun. By comparing satellite measurements of invisible radiation with earth-bound records of the sun's visible light, scientists should be able to predict some of these reactions and their effects on earth...

...bright mirrors. "I noticed them in six or eight places," Armstrong explained, "always in the same kind of place-at the bottom of a crater." Last week Cornell Astronomer Thomas Gold offered a dramatic explanation. The moon, he says, may have been scorched by a huge flare-up of heat and light within the solar system...

...surface despite the moon's constant bombardment by micrometeorites and solar particles, Gold calculates that the event was relatively recent-perhaps less than 30,000 years ago. It probably lasted only ten to 100 seconds. The small craters show the effect of the blast because they are natural heat traps. What was the origin of this fiery outburst, which Gold figures was 100 times more powerful than ordinary sunlight? Writing in the current issue of Science, Gold speculates that it came from the sun itself, possibly as the result of a collision with a large comet...

Picking tritons is illegal, but the law can't be policed. There are other, quite legal, ways in which we are steadily bringing about the end of the world. Just for an example, there's the Greenhouse Effect gone wild. Our heavy industry, oil heat, and combustion in general are putting too much CO2 into our air. CO2 in our atmosphere absorbs ultraviolet radiation from the sun (reflected off the earth) as heat. This is called the Greenhouse Effect. It was important in the evolution of the earth into a life-supporting planet. The world is getting hotter and hotter...

...appeal was not to take the heat off universities, especially in the areas where change inside the university will make a real difference. Nader himself has been one of the main agitators in the national law school reform movement. The point was that students who want to beat the system have to stop playing by the system's rules. Student bodies might get ROTC off the campus, and that might make a chink in ROTC, which might cut into the war effort. But maybe things would be quicker and more effective if the bodies worked on the Defense Department...
