But when we launch in idea into infinite space, and contemplate
the systems without number that fill it; here indeed we have a subject
truly worthy of the DEITY! Whoever supposes the fixed stars placed in a
concave sphere, as they appear to us, must have a narrow and contracted
idea of the SUPREME BEING; for one star appears large and another small,
because one is immensely distant from us in comparison of another.
Through Dr. Herschell’s large telescope many fixed stars appear double:
the Polar star is double; (but they are only stars at different distances
from us appearing nearly in the same line) some appear like a topaz,
others azure, others red; all are round, and many as perfectly defined
as a shilling is on black cloth. By telescopes we formerly could see
three times the number we can by the naked eye; and now, telescopes
having received further improvement, in the most crouded part of the
milky way, 116,000 have passed before the instrument in a quarter of an
hour. The Nebula of Andromeda must be composed of the united lustre of
many millions of stars. Agreeably to this, Dr. Herschell has noticed
single nebulous stars surrounded with a faint equable whiteness; such as
a system of Planets viewed at that distance from us might be supposed
to give: others he has seen, which have the appearance of yet unformed
systems. And there are, we may presume, points of view, in the immensity
of the Universe, in which all the fixed stars, accessible to the eye
or telescope from this station of ours, and all the inconceivable
space, through which they extend, vanish into a _nebula_, and almost an
indiscernible point. Such is the order and greatness of that Empire,
which these Discoveries, the farther they are pursued, must for ever
more and more present to our increasing admiration. Such the relation of
parts so astonishingly remote! Such the unity of intelligence, power,
and preserving goodness which pervades the whole! And why may not stars
be so remote, that their light may not have reached the Earth even since
the creation! We know that light takes more time in travelling from
the nearest stars to us, than we in making a West India voyage, (which
is usually performed in six weeks) a sound would not arrive to us from
thence in 50,000 years, nor a cannon-ball in a much longer time. The
Sun’s light could not therefore reach the fixed stars, and be reflected
back again with their lustre; of course they shine by their own light—if
so, they shine as our Sun, and consequently are Suns themselves.—Now,
as a principal of uniformity runs through the variety of nature, it is
reasonable to conclude these Suns to be centres of systems like ours;
and destined for the same noble purposes, viz. that of giving light,
heat, and vegetation, to various worlds that revolve round them, but
which are too remote for discovery, even with our best telescopes!
This idea is infinitely too great for the human mind; or indeed for
