Cold HI ejected into the Magellanic Stream
  We report the direct detection of cold HI gas in a cloud ejected from the
Small Magellanic Cloud (SMC) towards the Magellanic Stream. The cloud is part
of a fragmented shell of HI gas on the outskirts of the SMC. This is the second
direct detection of cold HI associated with the Magellanic Stream using
absorption. The cold gas was detected using 21-cm HI absorption-line
observations with the Australia Telescope Compact Array (ATCA) towards the
extra-galactic source PMN J0029$-$7228. We find a spin (excitation) temperature
for the gas of $68 \pm 20$ K. We suggest that breaking super shells from the
Magellanic Clouds may be a source of cold gas to supply the rest of the
Magellanic Stream.
