  Some few hundred million years after the big bang the Universe was
illuminated by the first stars and galaxies thereby bringing an end to the
cosmological dark ages. Since the installation of WFC3 on the Hubble Space
Telescope our ability to probe this critical period of the Universe's history
has dramatically changed with thousands of objects now identified within the
first billion years of the Universe's history. Our understanding of this period
of the Universe's history will further grow thanks to both the Atacama Large
millimetre/sub-millimetre Array and the James Webb Space Telescope.
