After several delays this telescope is planned to start operation in 2027. If this goal can be achieved the Thirty Metre Telescope (TMT) will be the one of the new generation of Extremely Large Telescopes (telescopes with more than 20 metres of aperture). With its diameter of 30 metres there are a lot of observations that can be made, such as seeing the first stars and galaxies in the universe, resolving galaxies within 33 million light years into single stars, exoplanet discovery and characterisation and much more.
