CHAPTER VI

THE SYSTEM OF THE STARS

The first step towards our knowledge of the starry heavens was made

when the unknown and forgotten astronomers of 2700 B.C. arranged the

stars into constellations, for it was the first step towards

distinguishing one star from another. When one star began to be known

as "the star in the eye of the Bull," and another as "the star in the

shoulder of the Giant," the heavens ceased to display an indiscriminate

crowd of twinkling lights; each star began to possess individuality.

The next step was taken when Hipparchus made his catalogue of stars

(129 B.C.), not only giving its name to each star, but measuring and

fixing its place--a catalogue represented to us by that of Claudius

Ptolemy (A.D. 137).

The third step was taken when BRADLEY, the third Astronomer Royal,

made, at Greenwich, a catalogue of more than 3000 star-places

determined with the telescope.

A century later ARGELANDER made the great Bonn Zone catalogue of

330,000 stars, and now a great photographic catalogue and chart of the

entire heavens have been arranged between eighteen observatories of

different countries. This great chart when complete will probably

present 30 millions of stars in position and brightness.

{82}

The question naturally arises, "Why so many stars? What conceivable

use can be served by catalogues of 30 millions or even of 3000 stars?"

And so far as strictly practical purposes are concerned, the answer

must be that there is none. Thus MASKELYNE, the fifth Astronomer

Royal, restricted his observations to some thirty-six stars, which were

all that he needed for his _Nautical Almanac_, and these, with perhaps

a few additions, would be sufficient for all purely practical ends.

But there is in man a restless, resistless passion for knowledge--for

knowledge for its own sake--that is always compelling him to answer the

challenge of the unknown. The secret hid behind the hills, or across

the seas, has drawn the explorer in all ages; and the secret hid behind

the stars has been a magnet not less powerful. So catalogues of stars

have been made, and made again, and enlarged and repeated; instruments

of ever-increasing delicacy have been built in order to determine the

positions of stars, and observations have been made with

ever-increasing care and refinement. It is knowledge for its own sake

that is longed for, knowledge that can only be won by infinite patience

and care.

The chief instrument used in making a star catalogue is called a

transit circle; two great stone pillars are set up, each carrying one

end of an axis, and the axis carries a telescope. The telescope can

turn round like a wheel, in one direction only; it points due north or

due south. A circle carefully divided into degrees and fractions of a

degree is attached to the telescope.

In the course of the twenty-four hours every star above the horizon of

the observatory must come at least once within the range of this

telescope, and at that moment the observer points the telescope to the

{83} star, and notes the time by his clock when the star crossed the

spider's threads, which are fitted in the focus of his eye-piece. He

also notes the angle at which the telescope was inclined to the horizon

by reading the divisions of his circle. For by these two--the time

when the star passed before the telescope and the angle at which the

telescope was inclined--he is able to fix the position of the star.

"But why should catalogues be repeated? When once the position of a

star has been observed, why trouble to observe it again? Will not the

record serve in perpetuity?"

The answers to these questions have been given by star catalogues

themselves, or have come out in the process of making them. The Earth

rotates on its axis and revolves round the Sun. But that axis also has

a rolling motion of its own, and gives rise to an apparent motion of

the stars called +Precession+. Hipparchus discovered this effect while

at work on his catalogue, and our knowledge of the amount of Precession

enables us to fix the date when the constellations were designed.

Similarly, Bradley discovered two further apparent motions of the

stars--+Aberration+ and +Nutation+. Of these, the first arises from

the fact that the light coming from the stars moves with an

inconceivable speed, but does not cross from star to Earth instantly;

it takes an appreciable, even a long, time to make the journey. But

the Earth is travelling round the Sun, and therefore continually

changing its direction of motion, and in consequence there is an

apparent change in the direction in which the star is seen. The change

is very small, for though the Earth moves 18-½ miles in a second, light

travels 10,000 times as fast. Stars therefore are deflected from their

true positions by Aberration, by {84} an extreme amount of 20.47" of

arc, that being the angle shown by an object that is slightly more

distant than 10,000 times its diameter.

The axis of the Earth not only rolls on itself, but it does so with a

slight staggering, nodding motion, due to the attractions of the Sun

and Moon, known as +Nutation+. And the axis does not remain fixed in

the solid substance of the Earth, but moves about irregularly in an

area of about 60 feet in diameter. The positions of the north and

south poles are therefore not precisely fixed, but move, producing what

is known as the +Variation of Latitude+. Then star-places have to be

corrected for the effect of our own atmosphere, _i.e._ refraction, and

for errors of the instruments by which their places are determined.

And when all these have been allowed for, the result stands out that

different stars have real movement of their own--their +Proper Motions+.

No stars are really "fixed"; the name "+fixed stars+" is a tradition of

a time when observation was too rough to detect that any of the

heavenly bodies other than the planets were in motion. But nothing is

fixed. The Earth on which we stand has many different motions; the

stars are all in headlong flight.

And from this motion of the stars it has been learned that the Sun too

moves. When Copernicus overthrew the Ptolemaic theory and showed that

the Earth moves round the Sun, it was natural that men should be

satisfied to take this as the centre of all things, fixed and

immutable. It is not so. Just as a traveller driving through a wood

sees the trees in front apparently open out and drift rapidly past him

on either hand, and then slowly close together behind him, so Sir

WILLIAM HERSCHEL showed that the stars in one {85} part of the heavens

appear to be opening out, or slowly moving apart, while in the opposite

part there seems to be a slight tendency for them to come together, and

in a belt midway between the two the tendency is for a somewhat quicker

motion toward the second point. And the explanation is the same in the

one case as in the other--the real movement is with the observer. The

Sun with all its planets and smaller attendants is rushing onward,

onward, towards a point near the borders of the constellations Lyra and

Hercules, at the rate of about twelve miles per second.

Part of the Proper Motions of the stars are thus only apparent, being

due to the actual motion of the Sun--the "+Sun's Way+," as it is

called--but part of the Proper Motions belong to the stars themselves;

they are really in motion, and this not in a haphazard, random manner.

For recently KAPTEYN and other workers in the same field have brought

to light the fact of +Star-Drift+, _i.e._ that many of the stars are

travelling in associated companies. This may be illustrated by the

seven bright stars that make up the well-known group of the "Plough,"

or "Charles's Wain," as country people call it. For the two stars of

the seven that are furthest apart in the sky are moving together in one

direction, and the other five in another.

Another result of the close study of the heavens involved in the making

of star catalogues has been the detection of DOUBLE STARS--stars that

not only appear to be near together but are really so. Quite a

distinct and important department of astronomy has arisen dealing with

the continual observation and measurement of these objects. For many

double stars are in motion round each other in obedience to the law of

gravitation, and their orbits have been computed. {86} Some of these

systems contain three or even four members. But in every case the

smaller body shines by its own light; we have no instance in these

double stars of a sun attended by a planet; in each case it is a sun

with a companion sun. The first double star to be observed as such was

one of the seven stars of the Plough. It is the middle star in the

Plough handle, and has a faint star near it that is visible to any

ordinarily good sight.

Star catalogues and the work of preparing them have brought out another

class--VARIABLE STARS. As the places of stars are not fixed, so

neither are their brightnesses, and some change their brightness

quickly, even as seen by the naked eye. One of these is called

+Algol+, _i.e._ the Demon Star, and is in the constellation Perseus.

The ancient Greeks divided all stars visible to the naked eye into six

classes, or "+magnitudes+," according to their brightness, the

brightest stars being said to be of the first magnitude, those not

quite so bright of the second, and so on. Algol is then usually

classed as a star of the second magnitude, and for two days and a half

it retains its brightness unchanged. Then it begins to fade, and for

four and a half hours its brightness declines, until two-thirds of it

has gone. No further change takes place for about twenty minutes,

after which the light begins to increase again, and in another four and

a half hours it is as bright as ever, to go through the same changes

again after another interval of two days and a half.

Algol is a double star, but, unlike those stars that we know under that

name, the companion is dark, but is nearly as large as its sun, and is

very close to it, moving round it in a little less than three days. At

one point of its orbit it comes between Algol and the Earth, {87} and

Algol suffers, from our point of view, a partial eclipse.

There are many other cases of variable stars of this kind in which the

variation is caused by a dark companion moving round the bright star,

and eclipsing it once in each revolution; and the diameters and

distances of some of these have been computed, showing that in some

cases the two stars are almost in contact. In some instances the

companion is a dull but not a dark star; it gives a certain amount of

light. When this is the case there is a fall of light twice in the

period--once when the fainter star partly eclipses the brighter, once

when the brighter star partly eclipses the fainter.

But not all variable stars are of this kind. There is a star in the

constellation Cetus which is sometimes of the second magnitude, at

which brightness it may remain for about a fortnight. Then it will

gradually diminish in brightness for nine or ten weeks, until it is

lost to the unassisted sight, and after six months of invisibility it

reappears and increases during another nine or ten weeks to another

maximum. "Mira," _i.e._ wonderful star, as this variable is called, is

about 1000 times as bright at maximum as at minimum, but some maxima

are fainter than others; neither is the period of variation always the

same. It is clear that variation of this kind cannot be caused by an

eclipse, and though many theories have been suggested, the

"+long-period variables+," of which Mira is the type, as yet remain

without a complete explanation.

More remarkable still are the "NEW STARS"--stars that suddenly burst

out into view, and then quickly fade away, as if a beacon out in the

stellar depths had suddenly been fired. One of these suggested to

Hipparchus the need for a catalogue of the {88} stars; another, the

so-called "Pilgrim Star," in the year 1572 was the means of fixing the

attention of Tycho Brahe upon astronomy; a third in 1604 was observed

and fully described by Kepler. The real meaning of these "new," or

"temporary," stars was not understood until the spectroscope was

applied to astronomy. They will therefore be treated in the volume of

this series to be devoted to that subject. It need only be mentioned

here that their appearance is evidently due to some kind of collision

between celestial bodies, producing an enormous and instantaneous

development of light and heat.

These New Stars do not occur in all parts of the heavens. Even a hasty

glance at the sky will show that the stars are not equally scattered,

but that a broad belt apparently made up of an immense number of very

small stars divides them into two parts.

THE MILKY WAY, or GALAXY, as this belt is called, bridges the heavens

at midnight, early in October, like an enormous arch, resting one foot

on the horizon in the east, and the other in the west, and passing

through the "+Zenith+," _i.e._ the point overhead. It is on this belt

of small stars--on the Milky Way--that New Stars are most apt to break

out.

The region of the Milky Way is richer in stars than are the heavens in

general. But it varies itself also in richness in a remarkable degree.

In some places the stars, as seen on some of the wonderful photographs

taken by E. E. BARNARD, seem almost to form a continuous wall; in other

places, close at hand, barren spots appear that look inky black by

contrast. And the +Star Clusters+, stars evidently crowded together,

are frequent in the Milky Way.

And yet again beside the stars the telescope reveals {89} to us the

NEBULÆ. Some of these are the Irregular Nebulæ--wide-stretching,

cloudy, diffused masses of filmy light, like the Great Nebula in Orion.

Others are faint but more defined objects, some of them with small

circular discs, and looking like a very dim Uranus, or even like

Saturn--that is to say, like a planet with a ring round its equator.

This class are therefore known as "+Planetary Nebulæ+," and, when

bright enough to show traces of colour, appear green or greenish blue.

These are, however, comparatively rare. Other of these faint, filmy

objects are known as the "+White Nebulæ+," and are now counted by

thousands. They affect the spiral form. Sometimes the spiral is seen

fully presented; sometimes it is seen edgewise; sometimes more or less

foreshortened, but in general the spiral character can be detected.

And these White Nebulæ appear to shun the Galaxy as much as the

Planetary Nebula; and Star Clusters prefer it; indeed the part of the

northern heavens most remote from the Milky Way is simply crowded with

them.

It can be by no accident or chance that in the vast edifice of the

heavens objects of certain classes should crowd into the belt of the

Milky Way, and other classes avoid it; it points to the whole forming a

single growth, an essential unity. For there is but one belt in the

heavens, like the Milky Way, a belt in which small stars, New Stars,

and Planetary Nebulæ find their favourite home; and that belt encircles

the entire heavens; and similarly that belt is the only region from

which the White Nebulæ appear to be repelled. The Milky Way forms the

foundation, the strong and buttressed wall of the celestial building;

the White Nebulæ close in the roof of its dome.

{90}

And how vast may that structure be--how far is it from wall to wall?

That, as yet, we can only guess. But the stars whose distances we can

measure, the stars whose drifting we can watch, almost infinitely

distant as they are, carry us but a small part of the way. Still, from

little hints gathered here and there, we are able to guess that, though

the nearest star to us is nearly 300,000 times as far as the Sun, yet

we must overpass the distance of that star 1000 times before we shall

have reached the further confines of the Galaxy. Nor is the end in

sight even there.

This is, in briefest outline, the Story of Astronomy. It has led us

from a time when men were acquainted with only a few square miles of

the Earth, and knew nothing of its size and shape, or of its relation

to the moving lights which shone down from above, on to our present

conception of our place in a universe of suns of which the vastness,

glory, and complexity surpass our utmost powers of expression. The

science began in the desire to use Sun, Moon, and stars as timekeepers,

but as the exercise of ordered sight and ordered thought brought

knowledge, knowledge began to be desired, not for any advantage it

might bring, but for its own sake. And the pursuit itself has brought

its own reward in that it has increased men's powers, and made them

keener in observation, clearer in reasoning, surer in inference. The

pursuit indeed knows no ending; the questions to be answered that lie

before us are now more numerous than ever they have been, and the call

of the heavens grows more insistent:
