only are there many suns in the heavens,
but they are of many colors. The North
Star shines with a pure white light, and
our sun is a dazzling yellow, but there
are other suns which through the tele-
scope appear, blue, green, purple and red.
Sirius, Affair, Deneb and Vega are blush
white; Aldebaran, Betelgeuse and Antar-
es are exceedingly bright red; Arcturus
Is a duller red than the others; Rigel is
blue and Capella is yellow.
The most brilliant effects in coloring
are found among the double stars. These
are stars which appear single to the maxi
ed eye, but on examination by the tele-
scope are found to consist of two or more
stars placed near together. When two so
placed are of different colors the result
is dazzling. In the constellation of the
Southern Cross there is a group which
appears like q piece of magnificent and
stupendous jewelry. Among many white
stars there are five green ones, one green
ish blue and two beautiful red ones A
large white star in one of the northern
consultations is accompanied by one of
rich purple color. In another case a
triple star consists of an orange red sun
with two companions of a bright emer-
aid green. One double star is formed by
a large orange sun with a small blue
companion.
The people who dwell on planets revolv-
ing around double suns of different color
must witness daily what to us would be
an extraordinary spectacle. They may
tryO al
the other purple Two suns may mingle
their rays, blue supn and a red sun
giving a purple light, or a blue sun and
yellow sun giving a green light.
The coloring is supposed to be due to
the condition and composition of the at
mosphere surrounding the stars. A red
star has an atmosphere which stops all
but the red rays of light. These colors
change from time to time Sirius which
is now bluish-white, is well known TO
have been red many hundreds of years
ago. These variations are still going on.
The photo-spectrescope has accomplish
ed wonders in discovering the colors OF
stars and the existence of new ones in
visible to the eye even with the telescope.
A few years ago at the Harvard Obser-
vatory the first photo-spectroscope null
tiple star was discovered UNEXPECTEDLY.
The star Mizar. the middle star of the
handle OF the big dipper. has been called
''nakedeye" double because it has a
visible companion, Alcor. close to it. But
RiccoiI in 1850 discovered with the tele-
scope that Mizar had a telescope double
Mizar seems to have been the first double
star discovered with a telescope. The
apparent distance between Mizar and Al
cor is nearly forty times the distance
that separates components of Mizar. The
telescope shows, too. that there are other
stars between Mizar and Alcor. Two
centuries after the telescope revealed two
stars In Mizar the spectroscope showed
that the brighter Of the components was
itself made up OF two stars. In photo
graphs taken at the Harvard Observa-
tory in 1859 the Kline in the spectrum OF
Mizar appeared double. In other plates
the line was single. in others X was hazy
A close scrutiny Of all the plates showed
that the line was double al intervals OF
ifty-two days. This proved to astrono-
mers that the brighter component OF Mi
Ear was really two stars
