WORLDS ILLUMINED BY TWO SUNS.
tAstronOmy has shown that many OF the
donhle stars which stud the heavens are really
svstems of worlds lit up with two suns emitting
Inherently colored rays of light, and revolving
around their common centre Oh gravity ne
ferring to the planets which must DC connected
with such system, Mr.. W. DOOerck remarks IN
Nature: When we reflect upon the complicated
nature of the orbits which the planets and comets
describe round our sun, we get some idea or
how remarkable must be the nature OF those
curves that planets describe round double
suns. Perhaps the same comets that dlsap-
near TO our gaze, leaving the sphere OF at
traction of the sun, are attracted, and for
fine become members of those wonderful
svstems Our mathematics do not suffice for
solving the problems that are suggested,
but il is not unlikely that, unless situated very
close 10 one or other of the suns-sO close that
the other appears not much larger than star,
though comparable in brightness TO the nearest
sun-tbe planets are whlTled out in the cold
space bv the gravitational influence of the
other sur, as very likely many minor planet
was elected from the solar system under the
influence of Jupiter.
What must be the nature of those worlds
Illuminated by two different suns, one yellow
and another purple Now rises the one, and
all is clothed in yellow; now the other, and
ulumined from complementary sources, every
object appears in its natural color. Then sets
the yellow sun, and what must be the diversit
of the effects as it approaches the horizon And
behold nature pnts on purple maDue'
Then also the sun sets, and in the darkness
Of night, though there is seldom night where
there are two suns, the starry heavens are seen
muoh the same there as here, except perhaps
for moons rejecting light from the differently
colored suns. Not only the play OF color must
there be more varied than mere, put phen0n-
ena of which We have not the falntest. idea,
must be produced also through the action OF
heat, electricity, and magnetism. Indeed,
upon subjects like these science gives no
information, and we may therefore give our
fancy free reins.
