...Sunlight TV Tube. Conventional TV pictures tend to fade out when the light in the room gets too bright. This is because the glowing substance (phosphor) on the face of the picture tube is a reflective powder. In sunlight or other strong light, the reflection gets brighter than the picture and washes the picture...
...long as these "dirty snowballs" stay far enough from the sun, as most of them do, they lead peaceful lives, but a plunge toward the center of the solar system is a wild adventure. As a comet approaches the sun, its surface is warmed by the strengthening sunlight. Layer after layer, the ices turn into gas. Soon the nucleus is surrounded by a rapidly growing cloud, of gas and dust boiled out of the solid nucleus. This cloud, the comet's head, may be many thousands of miles in diameter. It is so transparent that stars show through...
...head grows bigger, some of the fine material is blown out of it by the pressure of sunlight, which has more effect than gravitation on particles of proper size. This fine material forms the tail, which always points away from the sun no matter how the head is moving. It may become many millions of miles long. The light from the head and tail is partly reflected sunlight; the rest of it comes from atoms or molecules made to fluoresce by solar radiation...
...important new technique will be to observe the comet's tail with radio telescopes. If it is really full of peculiar chemical fragments (free radicals), as astronomers suspect, the fragments should be excited by sunlight and made to broadcast on characteristic wave lengths. The Naval Research Laboratory in Washington has turned its 50-ft. radio disk on the comet in the hope of detecting waves from hydroxl (OH) radicals. If astronomers find this odd stuff in comets, they may be able to trace it back into interstellar space. This may lead them, in turn, to new knowledge about what...
Shining in the sunlight that flooded the nave towered the figure that dominated the occasion (opposite). Gentle and merciful, yet awesome in its serene majesty, the figure stands 16 ft. tall, high above the floor of the nave, resting against a concrete cylinder that houses the echo organ and at the apex of a concrete parabolic arch that springs from the ground and spans the nave. In the great tradition of Byzantine religious art, the figure is elongated and primitively covered with a boxlike drape. But the head, feet and hands are done with expressive realism, the head forceful...
