Description of object:
The Small Magellanic Cloud (SMC) is an irregular
dwarf galaxy, possibly gravitationally bound to the Milky Way. Because of its
nearness to the Milky Way, it therefore belongs to the local group. The
distance to the solar system is about 200,000 light years and the SMC contains
about 5 billion suns. It has the NGC number 292.
Our wide angle image shows (right) the large globular
cluster NGC 104 (Type III), also known as 47 Tucanae. It is easily visible with
the naked eye. 47 Tucanae is the second brightest globular cluster after Omega
Centauri. It is located about 17,000 light years away from the solar system and
is therefore not part of the Magellanic Cloud. At the top of the image there is
NGC 362, also a globular cluster of type III. With a distance of about 27,000
light-years from the solar system NGC 362 is not part of the small Magellanic
Cloud either.
The two brightest
objects within the Magellanic Cloud are (left) NGC 395, an open star cluster
and (right) NGC 346, a diffuse nebula. Even to the naked eye the Small
Magellanic Cloud is a prominent feature of the southern night sky. |
