This bridge of gas is a star-forming site. ==X-ray sources== No X-rays above background were detected from either Cloud during the September 20, 1966, Nike-Tomahawk rocket flight nor that of two days later.
The LMC was not detected in the X-ray range 8–80 keV. Another was launched from same atoll at 11:32 UTC on October 29, 1968, to scan the LMC for X-rays.
An X-ray astronomy instrument was carried aboard a Thor missile launched from the same atoll on September 24, 1970, at 12:54 UTC and altitudes above , to search for the Small Magellanic Cloud and to extend observation of the LMC.
However, in 1986, Caldwell and Coulson found that field Cepheid variables in the northeast lie closer to the Milky Way than those in the southwest.
The light echoes of supernova 1987A are also geometric measurements, without any stellar models or assumptions. In 2006, the Cepheid absolute luminosity was re-calibrated using Cepheid variables in the galaxy Messier 106 that cover a range of metallicities.
Supernova 1987a—the nearest supernova in recent years—was in the Large Magellanic Cloud.
From 2001 to 2002 this inclined geometry was confirmed by the same means, by core helium-burning red clump stars, and by the tip of the red giant branch.

This distance has been confirmed by other authors. By cross-correlating different measurement methods, one can bound the distance; the residual errors are now less than the estimated size parameters of the LMC. The results of a study using late-type eclipsing binaries to determine the distance more accurately was published in the scientific journal Nature in March 2013.
In 2014, measurements from the Hubble Space Telescope made it possible to determine a rotation period of 250 million years. The LMC was long considered to be a planar galaxy that could be assumed to lie at a single distance from the Solar System.
