Magellanic Irregular galaxy has star
formation in clumps all across its center. The picture shows
the 2 cm radio emission, measured at the
Very Large Array;
the bright knots are probably super-star clusters.
The star formation in the northern section has a form of an
arc around a hole. There is a very bright UV source in the
hole which may have created the hole, by blowing out the
gas, and triggered star formation in the arc by compressing
and heating the gas there.
