Our
Milky Way galaxy is about 100,000 light-years across.
Our Earth is located on an outer spiral arm of the galaxy.
In Earth’s Northern Hemisphere,
the Night Sky in December, January and February does not
look as “hazy full of
stars”.
That
is because the Earth is facing out, toward the deep space, and we are gazing through
just
25,000 light-years of stars in that outer spiral arm --- seeing
fewer stars.
In
the summer months, the Earth is facing toward the center of the galaxy.
We are looking across about 75,000
light-years of star-packed space.
That is the distance between us
and the other side of the galaxy. So, the
sky is “hazy full” with billions upon billions of stars.
