1. James Webb telescope

 The James Webb Space Telescope (JWST) is a space observatory that was launched into orbit in 2018. It is named after former NASA administrator James E. Webb who led the agency from 1961 to 1968. JWST is designed to observe infrared radiation between 0.6 micrometers and 28 micrometers. This includes light emitted by stars at different stages of their evolution, nebulae, galaxies, and other astronomical objects.

 2. Hubble Space Telescope

 The Hubble Space Telescope (HST), often referred to as simply Hubble, is a space telescope operated by NASA. It was built to replace the earlier but similar Voyager program spacecraft, which were launched in 1977. HST has been used extensively since its launch, including observations of the planets Jupiter and Saturn, comets, supernovas, star clusters, galaxies, and many others.

 3. Kepler Space Telescope

 Kepler is a NASA Discovery-class space telescope launched in 2009. Its mission is to detect Earth-size exoplanets orbiting in the habitable zones of Sun-like stars. It is named after Johannes Kepler, whose laws of planetary motion are based on his 1619 book Harmonice Mundi.

 The James Webb Space Telescope (JWST) is a space observatory being developed by NASA. It will be the successor to Hubble and the first space-based infrared observatory. It is planned for launch in 2018.

     1. James Webb telescope

 The James Webb Space Telescope (JWST) is a space observatory that is being built by NASA. It is planned to launch in 2018. JWST will be able to look back into the early universe between 13 billion and 18 billion years ago. This is over 10 billion years before the Big Bang.

 2. Hubble Space Telescope

 The Hubble Space Telescope was launched into orbit in 1990 and has been working continuously since then. In its lifetime, it has discovered thousands of exoplanets and observed the formation of stars and galaxies.

 3. Kepler Space Telescope

 Kepler was launched in 2009. Its mission is to find planets outside our solar system using the transit method. In other words, Kepler looks at star systems that are similar to our own and watches them for any changes in brightness. If a planet passes in front of the star, it dims the light slightly, but not enough to notice. By measuring these slight dips in brightness, scientists can calculate the size of the planet relative to the size of the star.



   1. James Webb telescope is a space observatory that was launched into orbit in 2018. It is named after the NASA administrator from 1992-1998 who championed its construction. It has a 6.5 meter diameter mirror and is capable of observing objects at infrared wavelengths.

 2. James Webb Telescope's primary mission is to observe the first galaxies formed after the Big Bang. This is done by using the telescope's large mirror to gather light from these distant objects.

 3. The James Webb Space Telescope is expected to launch sometime in 2021. Its launch window opens in 2019 and closes in 2024.

 4. The James Webb Space Observatory cost $8 billion to build and launch. It is the most expensive scientific instrument ever built.

 5. The James Webb Space telescope is the successor to the Hubble Space Telescope. Hubble was launched in 1990 and ceased operations in 2013 due to age related issues.

 6. The James Webb Space Telescopes' mirror is 6.5 meters wide. That is larger than any other optical telescope in existence.
