Mine's bigger than yours

Article Abstract:

The Japanese National Astronomical Laboratory will be launching a new telescope in Hawaii. The telescope includes the biggest mirror used in telescopes world wide, which has been made thin in order to tackle some of the problems associated with size. The telescope will be able to detect objects far enough away to have occurred during the infancy of the universe. There may also be more information on dark matter obtainable from this new telescope.
