The Magellanic Clouds are small irregular galaxies orbiting our own larger Milky Way spiral galaxy. The Small Magellanic Cloud (SMC), pictured here, is about 250,000 light years away and contains a preponderance of young, hot, blue stars indicating it has undergone a recent period of star formation. There is evidence that the SMC is actually two galaxies superposed to appear as one. The bright blob near the right hand edge of the frame is a globular cluster near the outskirts of the Milky Way.
