Comment |
North is to the
top.
This beautiful
structure is in the Taurus molecular cloud. It is about 450
light-years away towards the constellation Taurus, in the Orion Arm
of our Milky Way galaxy.
Various dark nebulae accent the diagonal dust lane. The image
has two prominent dark regions that Edward Barnard identified and
photographed in 1905. At the upper-right is B211 and at the
lower-left is B216.
As one of the closest molecular clouds, this
region is an ideal place to study the formation of stars.
