Pioneer 10 becomes the first object to leave the solar system...
...process begins when solar UV damages basal cells near the surface of the skin, causing them to swell. The pain and redness, which appear a few hours after exposure, are caused by the dilation of blood vessels in the damaged area. The ensuing tan is the body's desperate effort to save its skin from further injury. Tiny granules of melanin, a brownish pigment made in specialized skin cells, rise to the surface in response to UV radiation and act as sunlight deflectors. Over the years, however, the beachgoer pays for this glamorous natural shield. The buildup of melanin...
Like most comets, I-A-A contains molecules of ammonia and nitrogen, along with water, presumed building blocks of the solar system. But another satellite, the International Ultraviolet Explorer, also found surprising indications of sulfur molecules. Said University of Maryland Astronomer Michael A'Hearn: "The sulfur may be one of the few things we see that actually reside in the comet's nucleus." The most stunning observational feat came when the big, 1,000-ft. radio telescope in Arecibo, PR., managed to bounce radar waves off the fleeting object and perhaps settled the old argument over whether cometary...
Ellis said speakers will discuss such topics as water pollution, hazardous waste and solar energy, and that tables will be set up where environmental groups can distribute literature...
...miles in an orbit that carries it from pole to pole, IRAS roughly follows the line on the earth's surface where day meets night. Along this pathway, the telescope can always face 90° away from the sun, yet catch rays of sunlight on its solar panels to make electricity to power itself...
