His first survey of a complete prominence, pictured in, and not simply intersected by, the slit of his spectroscope, was obtained July 1, 1869. Shortly afterwards the plan was successfully adopted by the whole band of investigators. A difference in kind was very soon perceived to separate these objects into two well-marked classes.
When the spectroscope was in its infancy it was suggested that possibly some difference might be found in the rays reflected from living matter, especially from vegetation, that might enable us to distinguish them from rays reflected by matter not endowed with life. But this hope has not been realized, nor does it seem possible to realize it.
Take two germ cells, one of a plant, another of an animal; no man by microscope or by chemical analysis, or by the magic power of the spectroscope, can detect the slightest difference between them, yet the one infallibly develops into a plant and the other into an animal.
The owner of this charming place was a pioneer in the application of the spectroscope to the analysis of the light of the heavenly bodies, and after nearly forty years of work in this field, is still pursuing his researches. The charm of sentiment is added to the cold atmosphere of science by the collaboration of Lady Huggins. Almost at the beginning of his work Mr.
During the past fifteen years the art of measuring the speed with which a star is approaching us or receding from us has been brought to a wonderful degree of perfection. The instrument with which this was first done was the spectroscope; it is now replaced with another of the same general kind, called the spectrograph.
Seaton picked out a distant star in their course and observed it through the spectroscope. Since it was found to contain copper in notable amounts, all agreed that its planets probably also contained copper. "Don't know whether we can stop that soon or not," remarked Seaton as he set the levers, "but we may as well have something to shoot at.
In the course of an hour the light passed on ahead, and ultimately it disappeared in the remote horizon. The nature of this phenomenon Nordenskiöld is unable to explain; and unfortunately he had not the opportunity of examining it with the spectroscope.
Does it consist of nothing but isolated particles, or is there a solid nucleus, the attraction of which tends to keep the mass together? No one yet knows. The spectroscope, if we interpret its indications in the usual way, tells us that a comet is simply a mass of hydrocarbon vapor, shining by its own light. But there must be something wrong in this interpretation.
In the new science of psycho-analysis he has already begun the work of bringing an infinity of subconsciousness into the light of day; it may be that in the evidence of telepathy which the psychic researchers are accumulating, he is beginning to grope his way into a universal consciousness, which may come to include the joys and griefs of the inhabitants of Mars, and of the dark stars which the spectroscope and the telescope are disclosing.
It was not, of course, much use applying this method to the planets, for we know that the light which comes from them to us is only reflected sunlight, and this, indeed, was proved by means of the spectroscope. But the stars shine by their own light, and this opened up a wide field for inquiry.
