A series of measures from sixty-two similar images gave the distance and position-angle of its companion with about the same accuracy attainable by ordinary micrometrical operations; and the method and upshot of these novel experiments were described in three papers remarkably forecasting the purposes to be served by stellar photography. The sacrifice was recompensed by conspicuous success.
The distance of Antares, though not very accurately known, is probably not far from 350 light-years. We may thus form a new picture of the two branches of the temperature curve, long since suggested by Lockyer, on very different grounds, as the outline of stellar life. On the ascending side are the giants, of vast dimensions and more diffuse than the air we breathe.
Thou art the Lord of all, thou art Omnipresent, thou art the Soul of all things, and thou art the active power pervading everything! The rulers of the several worlds, those worlds themselves, the stellar conjunctions, the ten points of the horizon, the firmament, the moon, and the sun, are all established in thee! Thou art the Supreme lord of all creatures, celestial or human!
You have to treat your count as being true beforehand, the moment you come to treat the matter at all. Our stellar attributes must always be called true, then; yet none the less are they genuine additions made by our intellect to the world of fact.
We know that the coloured flames seen around the sun during total solar eclipse consist of glowing hydrogen, and of glowing matter giving a line so near the sodium line that in the case of a stellar spectrum it would, probably, not be possible to distinguish one from the other.
But it is not the scientific mystery of heredity which awakens within us those human fears that lie so much deeper than the mere animal fear; for heredity alone could no more achieve this result than could the scientific mystery of a dreaded disease, a stellar or marine phenomenon.
Another important result of the Allegheny work was the abolition of the anomalous notion of the "temperature of space," fixed by Pouillet at -140° C. For space in itself can have no temperature, and stellar radiation is a negligible quantity.
They went into the Biltmore a Biltmore alive with girls mostly from the West and South, the stellar débutantes of many cities gathered for the dance of a famous fraternity of a famous university. But to Gordon they were faces in a dream.
A red star, in Russell's scheme of stellar evolution, is a cooler sun, vast in volume and far more tenuous than atmospheric air when in the initial period of the "giant" stage, but compressed and denser than water in the "dwarf" stage, into which our sun has already entered as it gradually approaches the last phases of its existence.
In recent times what we may regard as a new branch of astronomical science is being developed, showing a tendency towards unity of structure throughout the whole domain of the stars. This is what we now call the science of stellar statistics. The very conception of such a science might almost appall us by its immensity.
