    Washington: The powerful next-generation James Webb Space Telescope has released a treasure trove of full-colour images from deepest and sharpest infrared image of the distant universe to date to cosmic cliffs, birthplace of stars, blackhole, dying star's final "performance", as well as the atmosphere of distant planet. The $10 billion Webb telescope, is an international programme led by NASA, European Space Agency and the Canadian Space Agency. The images, taken by Webb's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI), marks the climax of nearly seven months of carefully orchestrated space operations since the telescope launched on December 25, 2021 The first image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Another is a landscape of "mountains" and "valleys" speckled with glittering stars. It is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by Webb, this image reveals for the first time previously invisible areas of star birth. Called the Cosmic Cliffs, Webb's seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest "peaks" in this image are about 7 light-years high. It also sheds light on the process of star formation. In another enormous new image, the telescope reveals never-before-seen details of a group of five galaxies called "Stephan's Quintet". The close proximity of Stephan's Quintet gives astronomers a ringside seat to galactic mergers, interactions "This enor ...
