Big Bang can be regarded as the final observational frontier in
assembling a coherent picture of cosmic history. During this period early
stars and galaxies formed and the Universe became bathed in ultraviolet
light for the first time. Sometime during this period hydrogen in the
medium inbetween galaxies also transitioned from a neutral gas to one that
was fully ionized. How and when did this `cosmic reionization’ occur
and were early star-forming galaxies the primary agents?  Recent
measures by ESA's Planck satellite suggest that reionization was a rapid
process occurring later than originally envisaged. This development raises
the exciting prospect that we may be able to directly observe the
first galaxies. Deep exposures with the Hubble Space Telescope
have provided the primary evidence that star-forming galaxies were
present during the relevant period. Detailed spectroscopy of these
galaxies is now required to address these important questions. I will
review the rapid progress being made in this area with current facilities,
and the prospects with upcoming ones, including the James Webb Space
Telescope due for launch in 2018 and extremely large
ground-based telescopes now under construction.  <span></span></span></i></p>
