The Tarantula Nebula as a template for extragalactic star forming
  regions from VLT/MUSE and HST/STIS
  We present VLT/MUSE observations of NGC 2070, the dominant ionizing nebula of
30 Doradus in the LMC, plus HST/STIS spectroscopy of its central star cluster
R136. Integral Field Spectroscopy (MUSE) and pseudo IFS (STIS) together
provides a complete census of all massive stars within the central 30x30
parsec^2 of the Tarantula. We discuss the integrated far-UV spectrum of R136,
of particular interest for UV studies of young extragalactic star clusters.
Strong HeII 1640 emission at very early ages (1-2 Myr) from very massive stars
cannot be reproduced by current population synthesis models, even those
incorporating binary evolution and very massive stars. A nebular analysis of
the integrated MUSE dataset implies an age of ~4.5 Myr for NGC 2070. Wolf-Rayet
features provide alternative age diagnostics, with the primary contribution to
the integrated Wolf-Rayet bumps arising from R140 rather than the more numerous
H-rich WN stars in R136. Caution should be used when interpreting spatially
extended observations of extragalactic star-forming regions.
