Most Advanced and Expensive Telescope in the World

The Most Advanced and Expensive Telescope in the World

The James Webb Space Telescope (JWST) is the most advanced and most expensive telescope ever built. It is a joint project between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). It has often been referred to as the 'successor' to the Hubble Space Telescope, which was launched in 1990.

The JWST is named after James E. Webb, who served as the second administrator of NASA from 1961 to 1968. It is designed to be the successor to the Hubble Space Telescope and is expected to be able to observe some of the earliest galaxies in the universe, study the formation of stars and planetary systems, and search for signs of life on exoplanets.

Here are some key facts about the James Webb Space Telescope:

  • The JWST has a 6.5-meter primary mirror, which is over 100 times more powerful than the Hubble's.

  • Unlike the Hubble, which observes primarily in visible and ultraviolet light, the JWST will observe primarily in the infrared part of the spectrum. This will allow it to see through clouds of gas and dust that can obscure visible light.

  • The JWST will be placed in a special orbit around the Sun called the second Lagrange point (L2), which is located approximately 1.5 million kilometers from Earth. From this vantage point, the telescope will have a clear view of the entire sky.

  • The construction and development of the JWST has been a complex and challenging process, with delays and cost overruns. The final cost of the project is estimated to be around $10 billion.

  • The JWST is expected to operate for at least 10 years, and its data will be used by astronomers around the world to answer some of the biggest questions about the universe.
