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.
[11] [12] In the 1756 star map of the French astronomer Lacaille, they are designated as le Grand Nuage and le Petit Nuage ("the Large Cloud" and "the Small Cloud"). [ 13 ] [ 14 ] John Herschel studied the Magellanic Clouds from South Africa, writing an 1847 report detailing 919 objects in the Large Magellanic Cloud and 244 objects in the Small ...
These observations show that most of the gas was stripped from the Small Magellanic Cloud about two billion years ago— but surprisingly, a second region of the stream was formed more recently from the Large Magellanic Cloud. The pink circles to the right mark the location of the Small and Large Magellanic Clouds. Date and time of data generation
The ratio between the black hole Schwarzschild radius and the observer distance to it is 1:9. Of note is the gravitational lensing effect known as an Einstein ring, which produces a set of two fairly bright and large but highly distorted images of the Cloud as compared to its actual angular size.
LMC X-1 is the first X-ray source detected in the Large Magellanic Cloud. [4] It was discovered in 1969, using data from an instrument carried by a Sandia Terrier-Sandhawk sounding rocket, launched from the Johnston Atoll on October 29, 1968. [5] [6] LMC X-1 is a persistently luminous X-ray binary. [4]
The Magellanic Stream is a stream of high-velocity clouds of gas extending from the Large and Small Magellanic Clouds over 100° through the Galactic south pole of the Milky Way. The stream contains a gaseous feature dubbed the leading arm . [ 1 ]
NGC 2210 is a globular cluster located in the Large Magellanic Cloud, in the constellation Dorado. It is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. It was first discovered by astronomer John Herschel on January 31, 1835. [1]
The Large and Small Magellanic Clouds are the largest satellite galaxies of the Milky Way and, unlike the rest of the satellite galaxies, are still actively forming stars — and at a rapid pace. The depth of these survey data can be appreciated by the number of stars visible in the outer regions of the galaxy, as seen in the lower part of the ...
