James Webb telescope: first images

By daniele

The James Webb Space Telescope (JWST) completed its first mission after submitting a fantastic photo to NASA.On Wednesday, a staff member of the Space Agency released an excellent picture of the stars the telescope took during its alignment operations. The photo shows several galaxies in focus and some distant stars.

At Christmas 2021, with 25 years and over $10 billion, the James Webb Space Telescope (JWST) was finally launched into space on the Ariane 5 rocket in Europe. Even though this self-alignment has not yet been completed, the researchers say they were overwhelmed by the test images already taken by this newborn telescope. “The images are as close to focus as the laws of physics allow,” Web Telescope vice-scientist at the Space Telescope Institute in Baltimore told CNN.

This first image clearly shows the capabilities of James Webb

  • The telescope makes sure it’s working well; this first image is also a clear indication of James Webb’s capabilities.
  • James Webb, 100 times more sensitive than the Hubble Telescope and active in the infrared region, has captured galaxies much further than before.
  • “The Web can look at any point in the sky for 2,000 seconds and get an incredibly deep view. Said, Mr. Rigby. “This is the future. No matter where we look, it’s a deep field. You can see the light of galaxies billions of years ago without sweating.And this process is just beginning.
  • The James Webb is equipped with four scientific instruments, but currently, only one near-infrared camera (NIRCam) is operational. NASA believes that the remaining three devices will be operational in June or July and will be able to start the scientific imaging process.
  • These images can capture early galaxies just a few hundred million years from the Big Bang and may change our understanding of the formation and evolution of galaxies.
