Text from APOD: Irregular galaxy NGC 55 is thought to be
similar to the Large Magellanic Cloud (LMC). But while the LMC is about 180,000 light-years away and is a well
known satellite of our own Milky Way Galaxy, NGC 55 is more like 6 million light-years distant and is a member of
the Sculptor Galaxy Group. Classified as an irregular galaxy, in deep exposures the LMC itself resembles a barred
disk galaxy. However, spanning about 50,000 light-years, NGC 55 is seen nearly edge-on, presenting a flattened,
narrow profile in contrast with our face-on view of the LMC. Just as large star forming regions create emission
nebulae in the LMC, NGC 55 is also seen to be producing new stars. This gorgeous galaxy portrait highlights a
bright core, telltale pinkish emission regions, and young blue star clusters in NGC 55.
