Bill Nye's Red Book / New Edition

by Bill Nye

Astronomers say that the tails of all comets are turned from the sun. I do not know why they do this, whether it is etiquette among them or just a mere habit.

A later writer on astronomy said that the substance of the nebulosity and the tail is of almost inconceivable tenuity. He said this and then death came to his relief. Another writer says of the comet and its tail that "the curvature of the latter and the acceleration of the periodic time in the case of Encke's comet indicate their being affected by a resisting medium which has never been observed to have the slightest influence on the planetary periods."

I do not fully agree with the eminent authority, though he may be right. Much fear has been the result of the comet's appearance ever since the world began, and it is as good a thing to worry about as anything I know of. If we could get close to a comet without frightening it away, we would find that we could walk through it anywhere as we could through the glare of a torchlight procession. We should so live that we will not be ashamed to look a comet in the eye, however. Let us pay up our newspaper subscription and lead such lives that when the comet strikes we will be ready.

Some worry a good deal about the chances for a big comet to plow into the sun some dark, rainy night, and thus bust up the whole universe. I wish that was all I had to worry about. If any respectable man will agree to pay my taxes and funeral expenses, I will agree to do his worrying about the comet's crashing into the bosom of the sun and knocking its daylights out.

THE SUN.

This luminous body is 92,000,000 miles from the earth, though there have been mornings this winter when it seemed to me that it was further than that. A railway train going at the rate of 40 miles per hour would be 263 years going there, to say nothing of stopping for fuel or water, or stopping on side tracks to wait for freight trains to pass. Several years ago it was discovered that a slight error had been made in the calculations of the sun's distance from the earth, and, owing to a misplaced logarithm, or something of that kind, a mistake of 3,000,000 miles was made in the result. People cannot be too careful in such matters. Supposing that, on the strength of the information contained in the old timetable, a man should start out with only provisions sufficient to take him 89,000,000 miles and should then find that 3,000,000 miles still stretched out ahead of him. He would then have to buy fresh figs of the train boy in order to sustain life. Think of buying nice fresh figs on a train that had been en route 250 years!

Imagine a train boy starting out at ten years of age, and perishing at the age of 60 years with only one-fifth of his journey accomplished. Think of five train boys, one after the other, dying of old age on the way, and the train at last pulling slowly into the depot with not a living thing on board except the worms in the "nice eating apples!"

The sun cannot be examined through an ordinary telescope with impunity. Only one man ever tried that, and he is now wearing a glass eye that cost him $9.

If you examine the sun through an ordinary solar microscope, you discover that it has a curdled or mottled appearance, as though suffering from biliousness. It is also marked here and there by long streaks of light, called faculae, which look like foam flecks below a cataract. The spots on the sun vary from minute pores the size of an ordinary school district to spots 100,000 miles in diameter, visible to the nude eye. The center of these spot's is as black as a brunette cat, and is called the umbra, so called because is resembles an umbrella. The next circle is less dark, and called the penumbra, because it so closely resembles the penumbra.
