Consider the following statements about Thirty Meter Telescope (TMT):
1. It is designed for observations from near-ultraviolet to mid-infrared.
2. It will explore the nature of extrasolar planets.
3. Its images will be 12 times sharper than the James Webb Space Telescope.
Which of the statements given above is/are correct?
(a) 3 only
(b) 1 and 2 only
(c) 1 and 3 only
(d) 1, 2 and 3
Explanation Statement 1 is correct: The TMT is designed for near-ultraviolet to mid-infrared (0.31 to 28 μm wavelengths) observations, featuring adaptive optics to assist in correcting image blur.
Statement 2 is correct: The TMT will help astronomers study the nature of extrasolar planets, including their atmospheres, composition, and the possibility of life by analyzing their light spectrum.
Statement 3 is not correct: TMT builds on a rich heritage of technical innovation and scientific exploration in astronomy, and represents a huge leap in capability. TMT will have more light gathering power than the largest 10 existing ground-based telescopes combined, and its images will be 12 times sharper than those from the Hubble Space Telescope and more than four times sharper than those from the James Webb Space Telescope.
