Super star cluster

Super star clusters are huge star clusters of very young large stars. They are thought to be precursors of globular clusters.[1] Their short-lived huge blue stars emit lots of UV radiation which ionises the surrounding gas. Examples are Westerlund 1 and 2 in the Milky Way, and R136 in the Larger Magellanic Cloud. Nearby galaxy NGC 1569 has two SSCs.
