Imagine friends! you are inside a dark room with nothing but a pinhole to view the outside world, how would you feel. That’s what humans have been feeling while trying to peer at the heavens through our previous telescopes so far. Now we have a huge window opened before us. This is possible because of the launch of latest advanced telescope by NASA the James Webb. This is the most advanced telescope yet and the pictures are jaw dropping.
The James Webb Space Telescope is the world's premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
Our view of the universe just expanded: The first image from Nasa’s new space telescope unveiled is brimming with galaxies and offers the deepest look of the cosmos ever captured. NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far.

The cosmic cliffs of a stellar nursery, a quintet of galaxies bound in a celestial dance: the James Webb Space Telescope released its next wave of images , heralding a new era of astronomy.
The Carina Nebula is one of the first targets of the James Webb Space Telescope.
Webb’s image is approximately the size of a grain of sand held at arm’s length, a tiny sliver of the vast universe. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying more distant galaxies, including some seen when the universe was less than a billion years old. This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks. And this is only the beginning. Researchers will continue to use Webb to take longer exposures, revealing more of our vast universe.
This image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, with many more galaxies in front of and behind the cluster. Much more about this cluster will be revealed as researchers begin digging into Webb’s data. This field was also imaged by Webb’s Mid-Infrared Instrument (MIRI), which observes mid-infrared light.
Webb’s NIRCam has brought distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.
Light from these galaxies took billions of years to reach us. We are looking back in time to within a billion years after the big bang when viewing the youngest galaxies in this field. The light was stretched by the expansion of the universe to infrared wavelengths that Webb was designed to observe. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions.
Other features include the prominent arcs in this field. The powerful gravitational field of a galaxy cluster can bend the light rays from more distant galaxies behind it, just as a magnifying glass bends and warps images. Stars are also captured with prominent diffraction spikes, as they appear brighter at shorter wavelengths.
Webb’s MIRI image offers a kaleidoscope of colors and highlights where the dust is – a major ingredient for star formation, and ultimately life itself. Blue galaxies contain stars, but very little dust. The red objects in this field are enshrouded in thick layers of dust. Green galaxies are populated with hydrocarbons and other chemical compounds. Researchers will be able to use data like these to understand how galaxies form, grow, and merge with each other, and in some cases why they stop forming stars altogether.

This is the Butterfly Nebula... it's the remains of an exploded star. Its "wings" are made of the super-heated guts of the dead star, and are more than 2 LIGHT YEARS across!!!Boom!
"Each will give humanity a view of the universe that we've never seen.
astronomy emphasises that while we appreciate the enormity of the universe, we also need to appreciate just how delicate earth’s own atmosphere is. We are speaking amidst intense heat waves across Europe , US and other parts of the world . As we explore universe we must understand how rare n precious Earth’s atmosphere, which enables life , is .
