First deep space images from James Webb Space Telescope released
Friday, July 15, 2022
The image, named Hubble Space Telescope, the predecessor to James Webb., shows thousands of galaxies in the galaxy cluster, about 4.6 billion light-years away from Earth. However, the area shown by the image is only a small portion of the sky. The blended image (at left) resulted from the stitching together of numerous smaller images obtained at multiple wavelengths with far greater depth than achieved by the
The telescope entered its current orbit around the L2from January 24, about 1,500,000 kilometers (932,057 mi) from , on the opposite side of Earth from the . This followed a month-long journey that began in late December 2021, following years of delays and several cost overruns. For its expected five- to ten-year service life, it is intended to study the most distant, and therefore the earliest formed after the .
During its journey, dubbed "30 days of terror" by, the telescope successfully unfurled its 21 feet (6 m) wide mirror, deployed its and cooled down to below 50 degrees as it traveled to the L2 Lagrange point.
L2 is a secure location for spacecraft where the gravitational pull of the Sun and the Earth is balanced. Full scientific operations will involve thirteen teams of scientists. The primary mission is to find the most distant and earliest galaxies formed after the Big Bang to help study the origins of the. The nominal mission time is five years, with a goal of ten. The location of its orbit is very different to the Hubble Space Telescope, which orbits much closer to Earth. James Webb's instruments face away from the Sun, giving a greater clarity to the images it will obtain compared to Hubble.

The United States National Aeronautics and Space Administration (NASA) began project development in 1996, planning for a launch in 2007 at a cost of USD550 million. After NASA contracted Northrop Grumman to build the telescope, mission managers estimated a 2010 launch would cost between one and 3.5 billion USD. Redesigns to reduce technical requirements pushed launch plans to 2013 for an estimated cost of USD4.5 billion. The US Congress ordered a project review in 2010 which delayed the launch again to 2015.
Due to an estimated cost of USD6.5 billion, the COVID-19 pandemic pushed the launch date to 2021.proposed canceling the telescope altogether in 2011. After a plan was made for a 2018 launch at a cost of USD8.8 billion, technical errors found in the telescope and the subsequent
