The Magellanic Bridge (MBR) [1] is a stream of neutral Hydrogen (HI) that links the two Magellanic Clouds, [2] with a few known stars inside it. [3] [4] It should not be confused with the Magellanic Stream, which links the Magellanic Clouds to the Milky Way. It was discovered in 1963 by J. V. Hindman et al. [5]

There is a continuous stream of stars throughout the Bridge linking the Large Magellanic Cloud (LMC) with the Small Magellanic Cloud (SMC). This stellar bridge is of greater concentration in the western part, representing bright young stars that don't travel very far in their short lifetimes, born from primordial-like gas in Star Formation Regions that have been pulled and become unbound ("tidally stripped") [6] from the weaker gravitational field of the SMC. There are two major density clumps, one near the SMC, the other midway between the galaxies, referred to as the OGLE Island . [1]
