No. Look harder, wmw. Try Wikipedia.
And you have misquoted the HubbleSite quotation. It should be:30 Doradus, located in the heart of the Tarantula nebula, is the brightest star-forming region in our galactic neighborhood.
That number 30 is there because it is (or was) the 30th brightest object in the constellation Dorado (as determined by the naked eye or by primitive telescopes). The brightest star in that constellation is Alpha Doradus, then comes Beta Doradus, then Gamma, Delta, etc. Doradus.
In de.wikipedia, start with 30 Doradus, then Schwertfisch (Sternbild)
EDIT: from http://en.wikipedia.org/wiki/Dorado
Even though the name Dorado is not Latin but Portuguese, astronomers give it the Latin genitive form Doradus
when naming its stars; they are treating it (like the adjacent constellation Argo Navis) as if it were a feminine proper name of Greek origin ending in -ō (like Io
), names that have a genitive ending in -ūs
