Super star cluster
A super star cluster (SSC) is a very massive young open cluster that is thought to be the precursor of a globular cluster. They typically contain a very large number of young, massive stars that ionize a surrounding H II region, similar to our Milky Way's so-called "Ultra dense H II regions (UDHIIs)". An SSC's H II region is in turn surrounded by a cocoon of dust. In many cases, the stars and the H II regions will be invisible to optical observations due to high levels of extinction. As a result, the youngest SSCs are best observed in radio and infrared.
The unique characteristics of SSCs are their large electron densities n_e=10^310^6 cm^ and pressures P/k_b=10^710^ K cm^.〔
