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. To the bottom left is the nebula IC 417 and above is NGC
1931. These two emission nebulae are about 7,000 light-years
distant.
In the above image, the "mouse over" view shows 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. |
