Small Magellanic Cloud

(move the mouse over thumbnails - please be patient until image downloads)

At a distance of about 200,000 light-years, the Small Magellanic Cloud (SMC) is one of the Milky Way's nearest neighbors. It is also one of the most distant objects that can be seen with the naked eye. Located in the constellation of Tucana, it appears as a hazy, light patch in the night sky about 3 degrees across. It looks like a detached piece of the Milky Way. SMC is a dwarf irregular galaxy, which has a diameter of about 7,000 light-years and contains several hundred million stars. The total mass of SMC is approximately 7 billion times the mass of the Sun. Some astronomers speculate that the SMC was once a barred spiral galaxy that was disrupted by the Milky Way to become somewhat irregular. It contains a central bar structure.
Several star clusters and H II regions could be seen on this image. For reference, please chech the annotated map.
The brightest and biggest object whithin SMC is NCC 346. Deeper image of the central part of the SMC can be found here.
