The James Webb Space Telescope it is the largest, most powerful and most complex in the world of space sciences. It cost about $ 10 billion and was billed by NASA as the tool that will solve the mysteries of our solar system, look beyond distant worlds around other stars, and explore the mysterious structures and origins of our universe and our place in it.
The James Webb Space Telescope is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency, and joins existing major observatories such as NASA’s Hubble Space Telescope and the Observatory NASA Space Chandra X-ray.
As a hallmark, Webb offers scientists “eyes” from infrared vision through the visible and ultraviolet part of the X-ray spectrum. A new era for the study of the cosmos.

“We are introducing humanity to a revolutionary new view of the cosmos from the James Webb Space Telescope – a view the world has never seen before,” said NASA Administrator Bill Nelson.
“These images, including the deepest infrared view of our universe ever taken, show us how Webb is will help uncover the answers to questions we don’t yet know how to ask; questions that will help us better understand our universe and humanity’s place within it, ”said Nelson.
Webb’s earliest observations tell the story of the hidden universe through every phase of cosmic history: from nearby exoplanets to more distant observable galaxies in the early universe.
“This is a unique and historic momentsaid Thomas Zurbuchen, associate administrator for the leadership of the science mission. “It took decades of willpower and perseverance to get here and I am immensely proud of the Webb team. These early images show us all we can achieve when we come together behind a common goal: solving the cosmic mysteries that connect us all. This is a dazzling glimpse of insights yet to come ”.

when it was launched into space
The James Webb Space Telescope was launched on December 25, 2021, aboard an Ariane 5 rocket, from the European spaceport in French Guiana, South America. After completing a complex sequence of deployment in space, Webb underwent months of commissioning during which his mirrors were aligned, his instruments calibrated to their space environment and prepared for scientific investigation.
Webb’s first observations were selected by a group of representatives from NASA, ESA, CSA and the Space Telescope Science Institute (STScl). These observations reveal the capabilities of Webb’s four cutting-edge scientific instruments.
The release of the first Webb images and spectra marks the beginning of his scientific operations, in which astronomers around the world will have the opportunity to observe everything from objects within our solar system to the early universe, using all of them. and four Webb tools.
