  Using Spitzer Space Telescope and Hubble Space Telescope observations of the
superbubble N51D, we have identified three young stellar objects (YSOs) in dust
globules, and made the first detection of a Herbig-Haro object outside the
Galaxy. The spectral energy distributions of these YSOs suggest young massive
stars with disk, envelope, and outflow cavities. The interstellar conditions
are used to assess whether the star formation was spontaneous or induced by
external pressure.
