Feedback from massive stars plays a critical role in the evolution of theUniverse by driving powerful outflows from galaxies that enrich theintergalactic medium and regulate star formation. An important source ofoutflows may be the most numerous galaxies in the Universe: dwarf galaxies.With small gravitational potential wells, these galaxies easily lose theirstar-forming material in the presence of intense stellar feedback. Here, weshow that the nearby dwarf galaxy, the Small Magellanic Cloud (SMC), has atomichydrogen outflows extending at least 2 kiloparsecs (kpc) from the star-formingbar of the galaxy. The outflows are cold, $T<400~{\rm K}$, and may have formedduring a period of active star formation $25 - 60$ million years (Myr) ago. Thetotal mass of atomic gas in the outflow is $\sim 10^7$ solar masses, ${\rmM_{\odot}}$, or $\sim 3$% of the total atomic gas of the galaxy. The inferredmass flux in atomic gas alone, $\dot{M}_{HI}\sim 0.2 - 1.0~{\rmM_{\odot}~yr^{-1}}$, is up to an order of magnitude greater than the starformation rate. We suggest that most of the observed outflow will be strippedfrom the SMC through its interaction with its companion, the Large MagellanicCloud (LMC), and the Milky Way, feeding the Magellanic Stream of hydrogenencircling the Milky Way.
