The Large Magellanic Cloud (LMC) is a dwarf galaxy and satellite galaxy of the Milky Way. [7] At a distance of around 50 kiloparsecs (163,000 light-years), [2] [8] [9] [10] the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (c. 16 kiloparsecs (52,000 light-years) away) and the possible dwarf irregular galaxy called the Canis Major Overdensity.
At the immense distance to the LMC, the parallax method is beyond the limits of current technology. Most estimates assume that R136 is at the same distance as the Large Magellanic Cloud. The most accurate distance to the LMC is 49.97 kpc, derived from a comparison of the angular and linear dimensions of eclipsing binary stars. [3]
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.
A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). ... The Large Magellanic Cloud is a satellite galaxy of the Milky Way, as is another nearby galaxy ...
An optical counterpart to NGC 5204 X-1 was discovered in 2001 using the X-ray data from Chandra and a series of observations in the visible spectrum from the Hubble Space Telescope. With an apparent magnitude of 19.7 despite a distance of more than 14 million light-years, which corresponds to an absolute magnitude of -8.7, it is most likely a ...
Ohnaka’s team used the Very Large Telescope Interferometer to study the star in 2005 and 2007, ... WOH G64 is one of the largest and most luminous stars in the Large Magellanic Cloud, and if it ...
In the night sky, R136 appears as a 10th magnitude object at the core of the NGC 2070 cluster embedded in the Tarantula Nebula in the Large Magellanic Cloud. [13] It required a 3.6 metre telescope to detect R136a as a component of R136 in 1979, [ 8 ] and resolving R136a to detect R136a1 requires a space telescope or sophisticated techniques ...
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 ...
