Giant 30-meter Telescope will look 13 Billion light years away 2

The Thirty Meter Telescope (TMT) will be the world’s most advanced and capable ground-based optical, will give it nine times the collecting area of the largest optical telescopes in use today. Will help scientists see some 13 billion light years away into the early years of the universe.

The Thirty Meter Telescope operating in wavelengths ranging from the ultraviolet to the mid-infrared, will be built at the summit of Hawaii’s Mauna Kea volcano, at the estimated cost of $1 billion.

The 30-meter aperture permits the telescope to focus more sharply than smaller telescopes by using the power of diffraction of light. The large aperture also collects more light than smaller scopes, allowing images of fainter objects. TMT will therefore reach further and see more clearly than previous telescopes by a factor of 10 to 100 depending on the observation.

In addition to providing nine times the collecting area of the current largest optical/infrared telescopes (the 10-meter Keck Telescopes), TMT will be used with adaptive optics systems to allow diffraction-limited performance, i.e., the best that the optics of the system can theoretically provide. This will provide unparalleled high-sensitivity spatial resolution more than 12 times sharper than what is achieved by the Hubble Space Telescope. For many applications, diffraction-limited observations give gains in sensitivity that scale like the diameter of the mirror to the fourth power, so this increase in size has major implications.



  • Observing capability in either a classical or service mode, which are both based on an efficient queue-based observing approach
  • Fully integrated adaptive optics (AO) telescope with multi-instrument Nasmyth mounted suite, which gives observational flexibility to enable rapid changes responsive to targets of opportunity and weather conditions
  • Extensive use of remote observing and eavesdropping capabilities in classical and service queue modes
