Therefore in looking through the luminous stuff that forms a comet's tail astronomers might well expect to see the stars displaced, but not a sign of this appears. It is difficult to imagine, therefore, what the tail can be made of.
Indeed, previously to the appearance of Olber's method, about the close of the last century, it furnished the easiest and most expeditious process hitherto devised, for calculating the parabolic elements of a comet's orbit. Invariable plane of the solar system.
Which was all very well, and yet as he turned Comet's head toward the Poison Hole ranch the blood was still hot on his brow, his thoughts were still busy with Winifred Waverly and the enigma she was to him, while his mind, still touched with the opiate of the loveliness of her, was filled with the picture she made in the moment of her flaming accusation.
Each of the planets solicits the comet to depart from its track, and though the amount of these attractions may be insignificant in comparison with the supreme controlling force of the sun, yet the departure from the ellipse is quite sufficient to produce appreciable irregularities in the comet's movement.
For owing to the great difference in the distances from the earth of the origin and extremity of such vast effluxes, the light proceeding from their various parts is transmitted to our eyes in notably different intervals of time. Consequently a luminous undulation, even though propagated instantaneously from end to end of a comet's tail, would appear to us to occupy many minutes in its progress.
Sometimes he lay in the shade a long time and thoughtfully gazed into the distance, dreaming as serious-minded youths dream the world over. But all Comet's dreams were centred in fields of broomstraw where birds lay hid and in the thrillings his nose told him there.
In the chapter on the sun we had to imagine something of the same kind to account for the corona, and the corona and the comet's tails may be really akin to each other, and could perhaps be explained in the same way. Now we come to a stranger fact still. Some comets go right through the sun's corona, and yet do not seem to be influenced by it in the smallest degree.
It consisted of stripes of different colors, starting from a point at the middle of the structure and widening toward the four sides. Her feet were tucked away under a bank of plum color sprinkled with salt; up her back ran a sort of comet's tail of puddled green. Over her shoulder and descending toward her chin, flowed a broadening delta of well-beaten egg. She was thankful for these colors.
The windows of the dark bungalows, one after another, leapt out, squares of ruddy brightness that flared and flickered and became steadily bright. Dark heads appeared looking seaward, a door opened, and sent out a brief lane of yellow to mingle and be lost in the comet's brightness. That brought me back to the business in hand.
So enormous are some of these tails that when the comet's head is close to the sun the tail extends far beyond the orbit of the earth. Faster still and faster flies the comet, for as we have seen it is a consequence of the law of gravitation that the nearer planets are to the sun the faster they move in their orbits, and the same rule applies to comets too.
