The lowest stage of incandescence is the familiar one of red heat. As it gains intensity, the quicker vibrations come in, and an optical balance of sensation is established at white heat. The final term of blue heat, as we now know, is attained by the photosphere.
He watches the snows that gather around the poles of Mars; he is on the lookout for the expected comet at the moment when its faint stain of diffused light first shows itself; he analyzes the ray that comes from the sun's photosphere; he measures the rings of Saturn; he counts his asteroids to see that none are missing, as the shepherd counts the sheep in his flock.
Had the ship been other than an engineless wreck, falling through a hundred and fifty million miles of emptiness into the flaming photosphere of a sun, everything would have seemed quite normal, including the errand Baird and Diane were upon, and the fact that they held hands self-consciously as they went about it. They skirted the bulkhead of the main air tank.
Whereas the above hypothesis is that the liquid film already exists beneath the visible photosphere, and that extinction cannot result until, in the course of further aggregation, the gaseous nucleus has become so much reduced, and the shell so much thickened, that the escape of the heat generated is greatly retarded.... M. Faye's hypothesis appears to be espoused by him, partly because it affords an explanation of the spots, which are considered as openings in the photosphere, exposing the comparatively non-luminous gases filling the interior.
The light of the nucleus would give us a continuous spectrum, like that of the Drummond light; but having to pass through the photosphere, as Kirchhoff's beam passed through the sodium flame, those rays of the nucleus which the photosphere emit are absorbed, and shaded lines, corresponding to the rays absorbed, occur in the spectrum.
These "dead points" are the limits of each electric field, which "create", we say in electrical work, opposing fields beyond them. Each one of these planets has its laya centre inside the sun's photosphere. Each planet has a line of solar energy with its "field" of solar energy not only a wireless telegraph, but a wireless lighting, heating, and life-giving system.
Here, then, was an action analogous to that which, as above suggested, happens around a sun-spot, where the masses of illuminated vapour constituting the photosphere are drawn towards the vortex of the cyclone, and simultaneously elongated into striæ: so forming the penumbra. At the same time there was furnished an answer to the chief objection to the cyclonic theory of solar spots.
The fact that the photosphere, except when broken by the so-called spots, lies like a great smooth sea, with no parts which lie above the general line, shows that it has a very different structure from the envelope which lies upon it. If they were both vaporous, there would be a gradation between them.
Applying this theory to a ``nova, like that of 1866 in the ``Northern Crown, which had been visible as a small star before the outbreak, and which afterward resumed its former aspect, we should have to assume that a yet shining sun had been approached by a dark body whose attraction temporarily burst open its photosphere.
