New Era of Space Exploration Begins: NASA releases first images of the universe from James Webb Telescope

The James Webb Space Tele­scope began releas­ing a new wave of cos­mic images on Tues­day, begin­ning a new era of space exploration.

NASA admin­is­tra­tor Bill Nel­son said every image is a new dis­cov­ery, adding, “Each will give human­i­ty a view of the uni­verse that we’ve nev­er seen before”.

On Mon­day, Webb revealed the clear­est image to date of the ear­ly uni­verse, going back 13.1 bil­lion years.

The most pow­er­ful space tele­scope ever built, the James Webb Tele­scope is designed to look far­ther into the cos­mos than ever before. And, the tele­scope has now start­ed to car­ry out its respon­si­bil­i­ty successfully.

First five images released on Tuesday

In one of the five images released on Tues­day, we see water vapor in the atmos­phere of a far­away gas plan­et. The spec­troscopy — an analy­sis of light that reveals detailed infor­ma­tion — was of plan­et WASP-96 b. The exo­plan­et was dis­cov­ered in 2014. Near­ly 1,150 light-years from Earth, WASP-96 b is about half the mass of Jupiter and zips around its star in just 3.4 days.

Con­struct­ed from almost 1,000 sep­a­rate image files, anoth­er image shows Stephan’s Quin­tet, a visu­al group­ing of five galax­ies, as observed from the Webb Telescope. 

The Webb tele­scope also revealed nev­er-before-seen details of Stephan’s Quin­tet, in which four in five galax­ies expe­ri­ence repeat­ed close encoun­ters, which pro­vide insights into how ear­ly galax­ies formed at the start of the universe.

Like­wise, the Webb image of Cari­na Neb­u­la, a stel­lar nurs­ery, famous for its tow­er­ing pil­lars that include “Mys­tic Moun­tain,” a three-light-year-tall cos­mic pin­na­cle cap­tured in an icon­ic image by Hub­ble, also bewil­dered behold­ers with its grand star-form­ing beauty.

The image has pre­sent­ed an unprece­dent­ed detail of the “moun­tains” and “val­leys” of a star-form­ing region called NGC 3324 in the Cari­na Neb­u­la, dubbed the “Cos­mic Cliffs,” 7,600 light years away.

In the begin­ning, the White House on Mon­day released a stun­ning shot that was over­flow­ing with thou­sands of galax­ies and fea­tures some of the faintest objects observed.

The image, known as Web­b’s First Deep Field, shows the galaxy clus­ter SMACS 0723, which acts as a grav­i­ta­tion­al lens, bend­ing light from more dis­tant galax­ies behind it towards the obser­va­to­ry, in a cos­mic mag­ni­fi­ca­tion effect.

The Webb Space Tele­scope has also revealed details of the South­ern Ring plan­e­tary neb­u­la that were pre­vi­ous­ly hid­den from astronomers. Plan­e­tary neb­u­lae are the shells of gas and dust eject­ed from dying stars.

How these images are set to change the course of understanding about the universe and the galaxies across the universe:
  • The astronomers expect a tor­rent of knowl­edge from the James Webb tele­scope, which has infrared fre­quen­cies that are not vis­i­ble to the human eye, but are extreme­ly rich in infor­ma­tion about the build­ing blocks of the universe.
  • Johns-Krull said in an inter­view that the tele­scope will also be a par­tic­u­lar­ly pow­er­ful source to look at plan­ets around oth­er stars.
  • Accord­ing to Johns-Krull, the tele­scope also opens many pos­si­bil­i­ties of find­ing a plan­et that sup­ports life, and knowl­edge about how galax­ies are formed.
  • NASA had ear­li­er said that with Webb’s obser­va­tions, researchers would be able to tell us about the make­up and com­po­si­tion of indi­vid­ual galax­ies in the ear­ly uni­verse for the first time.

The James Webb Tele­scope, which is orbit­ing the Sun at a dis­tance of a mil­lion miles (1.6 mil­lion kilo­me­ters) from Earth, in a region of space called the sec­ond Lagrange point, was launched in Decem­ber 2021 from French Guiana on an Ari­ane 5 rocket.

The total project cost is esti­mat­ed at $10 bil­lion, mak­ing it one of the most expen­sive sci­en­tif­ic plat­forms ever built, com­pa­ra­ble to the Large Hadron Col­lid­er at CERN.

Made up of 18 gold-coat­ed mir­ror seg­ments, Web­b’s pri­ma­ry mir­ror is over 21 feet (6.5 meters) wide.

How James Webb telescope images change understanding of the universe?

Images cap­tured by the James Webb Tele­scope are expect­ed to change our under­stand­ing of the uni­verse — and it has now start­ed with the first five high-res­o­lu­tion images in ‘microscopic’(in the uni­ver­sal scale) details.

It reveals the ear­li­est galax­ies, the birth of stars and even water vapor in the atmos­phere of a far­away gassy planet.

With the first five images released on Tues­day, the James Webb tele­scope has already start­ed to change our under­stand­ing about the uni­verse and also help us in find­ing rela­tion­ships between ear­ly uni­vers­es and plan­ets and star formation.

James Webb telescope images will change the human understanding of the universe in the following ways:
  • Astronomers say we have begun see­ing the uni­verse in wave­lengths we have nev­er seen before.
  • By observ­ing things like star and plan­et for­ma­tion and when galax­ies first formed, that can tell us a lot about how galax­ies formed.
  • Anoth­er major pur­pose of James Webb tele­scope is pro­vid­ing a detailed pic­ture of the ear­ly universe.
  • By observ­ing these uni­vers­es, astronomers will be able to exam­ine how galax­ies formed and how they evolved.
  • The James Webb Tele­scope will have a pow­er­ful infrared vision. This vision will also be able to study plan­ets that are orbit­ing oth­er stars.
  • Astronomers look at the James Webb Tele­scope’s image as a “new cam­era”. This tele­scope has a large mir­ror, so it can see things much more clear­ly than oth­er telescopes.
  • The James Webb tele­scope will reveal hun­dreds of mys­ter­ies of the uni­verse, includ­ing search for extrater­res­tri­als.
  • The image that was released on Tues­day shows the Pio­neer galax­ies, the galax­ies that formed in the first few hun­dred mil­lion years after the Big Bang.

The James Webb Tele­scope has final­ly opened a new win­dow to the uni­verse and with its suc­cess, let’s hope that our future gen­er­a­tions would be able to mine Gems, trav­el­ling far and wide in the universe.
