...about atmospheric pressure at the Martian surface, the spectrograms were of such high quality that they revealed unexpected absorption lines which had been indistinguishable in spectrograms recorded by less sensitive instruments. After careful analysis, Kaplan concluded that many of the absorption lines could have been caused only by reflected sunlight passing through hydrogen compounds in the Martian atmosphere...
...elsewhere. The pliers only made the arrival possible." In recent years, Rickey's pliers - along with welding torch and sheet-metal cutters - have produced whole families of curiously moving metal sculptures that gambol and gimbal in the wind, slicing segments of time like pendulums or spinning until the sunlight splinters into a spectral blur (see color...
...experiment Pasochoff and Pollack are directing involves "Baily's beads"-- an astronomical metaphor for the tiny glints of sunlight which appear to ring the moon instants before the achievement of a total eclipse. The "beads" can only be observed near the edge of shadow of totality -- either slightly inside it or slightly beyond it -- and present tracking predictions indicate that the Baker-Nunn telescope will be favorably situated for photographing them...
...phenomenon arises when the last rays of sunlight before totality gleam through the valleys and depressions of the mountainous lunar surface, creating, in effect, a "perforated" ring of sunlight about the edge of the moon. By accurately timing the event, the experimenters plan to collate more precise measurements of the moon's diameter...
...form of visible light. Thus, Sun suggests, in a strip less than 100 miles wide alongside the lunar terminator-the line that divides the moon's areas of day and night-the moon emits light of its own, which may be almost as intense as its reflected sunlight...
