The Milky Way is one of the many galaxies in the universe and the Sun is
one of the 100 billion stars it has in it. The Milky Way is so big in
size that it takes light about 100 thousand years to travel from end to
end. It tends to look patchy because in some parts of the galaxy the
stars are closer to each other,
as a result of
which those parts tend to shine out brighter than the others, in other
parts dark nebulae block out the light thus giving a patchy effect.
Galaxies are of elliptical, irregular and spiral types, the Milky Way is
a spiral type of galaxy. It has a curved arm of stars which radiate
from a glowing center. The brightest part of the Milky Way is in the
constellation called Sagittarius. The Sun and its family are
approximately 30,000 light years from the center of the Milky Way. The
nearest galaxy to our own is the Magellanic cloud which is about
1,50,000 light years away.
