NASA recently released the deepest and sharpest infrared image of our universe. The image is a cluster of galaxies names SMACS 0723. The cluster shows the presence of thousands of galaxies.
This image shows the Galaxy cluster SMACS 0723 as it believed to be 4.6 billion years old, with many other galaxies in front and behind this cluster.
Scientists believed that this universe is formed around 13.7 billion years ago.
This web's NIR cam has brought distant galaxies into sharp, they have very small tiny and faint structure that have never seen before that, including tha star cluster which can be seen in this picture.
The powerful gravitational field of a galaxy cluster can bend the light ray from more distant galaxies as you seen in this image. The starts look so brighter with shorter wavelength.
The web highlights the dust as the dust is the major ingredient for star formation and ultimately life itself. Blue galaxies contain little dust and also contains stars. The red object in this field contains more thick layers of dust. Green galaxies shows the presence of hydrocarbons and other chemical compounds their. These data will be helpful for the researchers to understand the formation of galaxies, how they grow and their merging with each other.
How we are looking back ??
Scientists believe that light from these galaxies took billions of years to reach us. As we are viewing the lights we are viewing back as we are seeing the youngest galaxies. This web is designed to observe the light which was stretched by the expansion of the universe. As soon as more images will come scientists will learn more about galaxies, messes, ages, histories and the composition of this universe.
What is a james web telescope?
It is a space telescope which can conduct infrared astronomy. It is greatly improved, it can provide infrared resolution and can view sensitive objects that are may be too old, faint or distant. It is Advanced than the Hubble telescope.
Cost:
It costs 10 Billion dollars.
Launched date:
It is launched at December 25, 2021.
What is the mission of James web telescope?
Scientists want to know about the formation of our universe. They also wanted to find the first galaxy that is formed is the early universe. This is why the telescope has been formed it can see deeply into the universe, opening up a new era of the cosmology.
Why it is named James web Telescope?
The name of this telescope was named after james E. Webb. He was the administrator of the NASA from February 1961 to October 1968. A tribute to him as he done a great job in this field.
How long does James web telescope can travel?
James web telescope covers most of the distance. It has already completed 80 percent of the distance according to NASA's tracker.
Who designed the James web telescope?
Bay area scientists now feeling proud on the formation of James web telescope. It was developed at Lockheed Martin in palo Alto.
What is the difference between Hubble's telescope and James web telescope?
James web telescope mirror is three times largest than Hubble's telescope. Hubble's captures the pictures at visible and ultraviolet light, but the James web telescope capture the universe in infrared spectrum. James web telescope can capture the image in less time while Hubble's telescope took more time usually weeks. James web telescope is at long distance from the orbit of earth while Hubble is much closer to orbit of earth.
What is a Galaxy?
Galaxy may be defined as the bound system if stars. It contains gases, dust and dark matter. The word galaxy is derived from the Greek language literally meaning the milky. As the name is assigned The milky way.
