  Magellanic Cloud
The Large Magellanic Cloud and the Small Magellanic Cloud, are conspicuous objects in the southern hemisphere.
The Large Magellanic Cloud, in the constellations of Dorado and Mensa, at its distance of 179,000 light years, is the second nearest external galaxy.

 The Small Magellanic Cloud, SMC
Irregular Galaxy SMC, the Small Magellanic Cloud (NGC 292) in Tucana
Like its larger apparent neighbor, the Large Magellanic Cloud, the Small Magellanic Cloud was certainly known to the ancient southerners, and was probably mentioned by Amerigo Vespucci in a letter written during his third voyage about 1503-4, but became known to us only when Magellan went on his journey around the world, in 1519.
The main body of the Small Magellanic Cloud has been assigned NGC 292 in Dreyer's catalog, which is now sometimes used for this galaxy.

 The Large Magellanic Cloud, LMC
The Large Magellanic Cloud, together with its apparent neighbor and relative, the Small Magellanic Cloud, are conspicuous objects in the southern hemisphere, looking like separated pieces of the Milky Way for the naked eye.
The Large Magellanic Cloud, at its distance of 179,000 light years, was longly considered the nearest external galaxy, until in 1994, the Sagittarius Dwarf Elliptical Galaxy was discovered at only about 80,000 light years.
On February 24, 1987, supernova 1987A occurred in the Large Magellanic Cloud, which was the nearest observed supernova since Keplers, which occured before the invention of the telescope.

 Vogelstrausskluft | Small Magellanic Cloud
Like its sister, the Large Magellanic Cloud, the Small Magellanic Cloud as well is a galaxy, the second closest to our earth.
The reason for the fusion of the two galaxies and the deformation of the object could be a collision with the Large Magellanic Cloud in the past and the neighbourhood to our much larger Milky Way.
An indication for that assumption is the Magellanic Stream, a stream of gas caused by gravitation forces, that connects these three galaxies.

 Leavitt Note
Fifty-nine of the variables in the Small Magellanic Cloud were measured in 1904, using a provisional scale of magnitudes, and the periods of seventeen of them were published in H.A. 60, No. 4, Table VI.
The faintness of the variables in the Magellanic Clouds seems to preclude the study of their spectra, with our present facilities.
It is hoped that a systematic study of the light changes of all the variables, nearly two thousand in number, in the two Magellanic Clouds may soon be undertaken at this Observatory.

 The Small Magellanic Cloud   (Site not responding. Last check: 2007-11-04)
The Small Magellanic Cloud (SMC) is the second nearest galaxy to the Milky Way, (the LMC being the nearest) and is at the distance of about 240,000 light years, quite close enough for it to be resolved into individual stars on this colour picture made from plates taken on the UK Schmidt Telescope.
The shape of the SMC defies description and it is therefore classified as an 'irregular' galaxy.
Since the SMC is the least massive of the three it is the most likely member of this interacting trio to be seriously distorted by the encounter.

 Small Magellanic Cloud (Star Fleet Universe) - Wikipedia, the free encyclopedia
The Small Magellanic Cloud is relevant to the wider Star Fleet Universe not merely due to its own unique attributes, but also to its importance before, during and after the Andromedan War.
The SMC is home to a number of starfaring races, which developed similar propulsion technologies to those of the Milky Way Galaxy, but created a number of unique technologies, such as the use of warp-tuned lasers, distortion generators and a multi-layer shielding system.
However, the Magellanic races were conquered by the Andromedans as part of their eventual plans to conquer the Milky Way Galaxy.

 Young supernova remnants not dusty enough, according to UC Berkeley astronomers
The discrepancy presents a challenge to scientists trying to understand the origins of stars in the early universe, because dust produced primarily from exploding stars is believed to seed the formation of new-generation stars.
Because supernovae in the Small Magellanic Cloud experience conditions similar to those we expect for early galaxies, this is a unique test of dust formation in the early universe."
Because of this, however, "the dust content and the abundance of heavy elements in the Small Magellanic Cloud are much lower than in our galaxy," she said, "while the interstellar radiation field from stars is more intense than in the Milky Way galaxy.
