The James Webb Space Telescope: Reveals a New Era in Astronomy
The James Webb Space Telescope, also known as JWST or Webb, will have a 6.5-meter primary mirror and be a sizable infrared telescope. In 2021, an Ariane 5 rocket will launch the telescope from French Guiana.
The Webb telescope, which will be used by hundreds of astronomers throughout the world, will be the best observatory in the coming ten years. It will investigate every stage of the evolution of our solar system, from the earliest bright glimmers after the Big Bang to the formation of solar systems capable of supporting life on Earth-like planets. The "Next Generation Space Telescope" (NGST), formerly known as the "Webb Telescope," was renamed in September 2002 in honour of a former NASA administrator, James Webb.
The National explores five unique characteristics of the James Webb Space Telescope. The telescope will enable us to observe the universe between 100 and 250 million years after its creation. The galaxy cluster is seen in the first photograph from the telescope, which was unveiled on July 12. The light used to create this image has travelled for more than 13 billion years. Although Hubble had already photographed this region, James Webb's observations reveal the galaxy cluster in astonishing detail. According to NASA, it intends to explore the last 13.5 billion years in order to make new discoveries. The telescope will be able to pick out an object's heat source by picking up infrared light.
The cameras on the space observatory are so sensitive that they can detect a bumblebee's heat signature. The mirror of a telescope aids in reflecting light into its cameras. The observatory will capture more light, the better the mirror. JWST contains 18 primary hexagonal mirrors, which, when combined, resemble a honeycomb. Its circumference is 6.5 meters in total. The mirror is 100 times more powerful and six times larger in area than Hubble's. The mirror is coated with a small layer of gold to enhance infrared light reflection.
JWST can observe farther distances than Hubble since it is situated much farther from the Earth and in a different orbit.
The telescope orbits the Sun as opposed to the Earth. Although it is parallel to Earth, it is 1.5 million kilometres away and four times farther away than the Moon. A Lagrange point is where this location in space is located. In order to protect the mirror from the sun, it is maintained at a temperature of minus 233 C. It is covered in a five-layer sun shield the size of a tennis court that dilutes the host star's heat by a factor of more than a million. Studying the atmospheres of exoplanets, or planets outside the Solar System, is one of the telescope's principal goals. It will search for oxygen in planets' atmospheres in faraway galaxies.
