N180B in the Large Magellanic Cloud
N180B is an active region of star formation in the irregular galaxy, the Large Magellanic Cloud (LMC). Residing only 160,000 light-years away, the LMC is one of the nearest galaxy neighbors to our own Milky Way.
This particular region within the LMC contains some of the brightest clusters of stars known to exist. These clusters are known as "OB associations" because they contain stars of class O and class B, two of the brightest and hottest classes of stars. Class O stars can be more than a million times brighter than our Sun.
