A Milky Way Band
Explanation: Most bright stars in our
Milky Way Galaxy
reside in a disk. Since our
Sun
also resides in this disk, these stars
appear
to us as a
diffuse band
that circles the sky. The
above panorama
of a
northern band
of the
Milky Way's disk
covers 90 degrees and is a digitally created mosaic of several independent exposures. Scrolling right will display the rest of this spectacular picture. Visible are many
bright stars
,
dark dust lanes
,
red emission nebulae
,
blue reflection nebulae
, and
clusters of stars
. In addition to all this matter that we can see,
astronomers
suspect there exists even more
dark matter
that we cannot see.
