North is to the right.
NGC 1907 is an
open star cluster in the constellation Auriga. At a distance of
about 4500 light-years, the cluster contains about 30 stars. At the
right, is the open cluster M38 at a distance of about 4000 ly. At
the bottom left is the nebula IC 417 and above is NGC 1931. These
two emission nebulae are about 7,000 light-years distant.
Surrounding everything is a portion of the
Taurus Molecular Cloud. This cloud is in the foreground, at a
distance of only 430 light-years. The Taurus cloud is a stellar
nursery for newly formed stars. |
