The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy , the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [ 1 ] [ 3 ] and contains several hundred million stars. [ 5 ]
This makes it feasible to use them as indicators of distance. Recently, they have been used to give direct distance estimates to the Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC), Andromeda Galaxy and Triangulum Galaxy. Eclipsing binaries offer a direct method to gauge the distance to galaxies to a new improved 5% level of accuracy ...
The Large Magellanic Cloud is of type SBm, while the Small Magellanic Cloud is an irregular (Im). The different elements of the classification scheme are combined — in the order in which they are listed — to give the complete classification of a galaxy.
A similar five-day cepheid variable in the Small Magellanic cloud she found to be about one ten-thousandth as bright as our five-day Delta Cepheus. Using the inverse-square law, she calculated that the Small Magellanic cloud was 100 times as far away as Delta Cepheus, thus having discovered a way to calculate the distance to another galaxy.
The Large Magellanic Cloud and its neighbour and relative, the Small Magellanic Cloud, are conspicuous objects in the southern hemisphere, looking like separated pieces of the Milky Way to the naked eye. Roughly 21° apart in the night sky, the true distance between them is roughly 75,000 light-years.
The Large Magellanic Cloud is considered a satellite galaxy of the sprawling Milky Way, as is another galaxy called the Small Magellanic Cloud. Both are smaller than our galaxy and offer different ...
The Large Magellanic Cloud is a satellite galaxy of the Milky Way, as is another nearby galaxy called the Small Magellanic Cloud. Both are smaller than our galaxy and offer different galactic ...
The discovery of a faint spiral structure [17] in the Large Magellanic Cloud led de Vaucouleurs to further divide the irregular galaxies into those that, like the LMC, show some evidence for spiral structure (these are given the symbol Sm) and those that have no obvious structure, such as the Small Magellanic Cloud (denoted Im). In the extended ...
