James Webb telescope takes super sharp view of early cosmos


James Webb telescope takes super sharp view of early cosmos: The very first picture to be taken with the brand new James Webb Space Telescope in full colour has been released, and it does not fail to impress.

It is believed that this image is the deepest and most detailed infrared view of the Universe that has ever been captured. It contains light from galaxies that has travelled many billions of years to reach us.

During a briefing at the White House, US Vice President Joe Biden was presented with the image.

On Tuesday, NASA is planning to hold a global presentation during which they will reveal additional first-look images taken by James Webb.

President Biden made the remark that “these images are going to remind the world that America can do big things, and remind the American people, especially our children, that there’s nothing beyond our capacity.” “These images are going to remind the world that America can do big things,”

“We are able to see opportunities that no one else has ever seen before. We have the ability to travel to locations that have never been explored before.”

Following in the footsteps of the illustrious Hubble Space Telescope is the ten billion dollar James Webb Space Telescope (JWST), which was successfully launched on December 25 of last year.

It is designed to carry out a wide variety of observations of the sky, but it has primarily two objectives. One objective is to capture images of the very first stars to shine in the Universe more than 13.5 billion years ago, and the other objective is to investigate distant planets to determine whether or not they might support life.

The picture that was revealed in front of President Biden highlights Webb’s capabilities to pursue the first of these goals.

You are looking at a galaxy cluster located in the constellation Volans, which is located in the Southern Hemisphere, and it is known by the cumbersome name of SMACS 0723.

In reality, the distance to the cluster is not nearly as great as one might think; it is “only” about 4.6 billion light-years away. However, due to the enormous mass of this cluster, the light emitted by objects that are located an extremely significant distance away has been bent and amplified.

This is a gravitational effect, which can be thought of as the astronomical version of a zoom lens for a telescope.

Webb, with its 6.5-meter-wide golden mirror and super-sensitive infrared instruments, was able to detect in this picture the distorted shape (the red arcs) of galaxies that existed only 600 million years after the Big Bang. This was accomplished by analysing the light emitted by the early universe (the Universe is 13.8 billion years old).

Additionally, it is even more wonderful than that. According to the quality of the data produced by Webb, scientists are able to deduce that the telescope is sensing space much further away than even the most distant object depicted in this image.

As a direct result of this, it’s entirely feasible that this viewing field of the cosmos is the deepest one that’s ever been acquired.

“The speed of light is approximately 186,000 miles per second. And the light that you are witnessing emanating from one of those minuscule specks has been travelling for more than thirteen billion years “said Nasa administrator Bill Nelson.

“And just so you know, this is only the first picture; there are many more that came before this one. They have retraced their steps approximately 13.5 billion years back in time. Given that the age of the universe is estimated to be 13.8 billion years, you are effectively going back to the beginning of time.”

On Tuesday, additional colour imagery from Webb will be made available for public consumption by NASA and its international partners, the space agencies of Europe and Canada.

One of the topics that will be talked about will have some bearing on the other overarching goal, which is the investigation of planets that are not in our Solar System.

Webb conducted research on the atmosphere of the giant planet WASP-96 b, which is located more than one thousand light-years away from Earth. It will provide us with information regarding the chemical make-up of that atmosphere.

WASP-96 b has an orbit that is way too close to its parent star for there to be any chance of there being life there. However, one day it is hoped that Webb will discover a planet that has gases in its air that are comparable to those that shroud the Earth. This would be a tantalising prospect that might hint at the presence of life.

In the past, producing this kind of result required Hubble to stare at the sky for an extended period of time. After only 12.5 hours of observations, Webb was able to determine what its super-deep objects were.

The experts working for NASA are certain that the Webb space telescope will live up to its potential.

Dr. Amber Straughn, a deputy project scientist, commented on the further release that took place on Tuesday, saying, “I have seen the first images, and they are spectacular.”

“Simply taken as images, they are incredible in and of themselves. What excites me the most, however, are the hints of the detailed scientific work that we will be able to do with them “she mentioned it to BBC News.

Dr. Eric Smith, who is the programme scientist for the James Webb Space Telescope project, expressed his belief that the general public understands the importance of the new telescope.

“I believe that the design of Webb, as well as the way that Webb appears, is a large part of the reason why the general public is so interested in this mission. It has the appearance of a time machine from the distant future.”
