A new dawn has begun to look into the deep, deep, deep cosmos.
Scientists have released the first long-awaited full-color scientific images captured by the James Webb Space Telescope, the most powerful instrument of its kind ever built. The colossal telescope orbits about a million miles from Earth and is positioned to look at some of the first galaxies and stars ever born. Looking at these objects means looking back in time billions of years, because this ancient light takes so long to reach us (or, more precisely, to reach the $ 10 billion Webb telescope).
This first batch of unprecedented images includes views of some of the most distant galaxies, a giant star nursery, and colossal cosmic clouds. It also offers a unique view of a giant planet beyond our solar system. (Memes aren’t bad either.)
“Webb’s mission is open to business today,” NASA astronomer Michelle Thaller said in the image presented Tuesday morning. “And that’s just the beginning. The best is yet to come …”

The Webb Telescope is the successor to the legendary Hubble Space Telescope, which has captured unprecedented stellar views for more than three decades. But the Webb telescope, with a gold mirror more than two and a half times larger than Hubble’s, has the ability to see much fainter objects and will look through thick, previously impenetrable cosmic dust clouds.
Take a look at five of the most anticipated space images ever.
SMACS 0723
Webb saw a population of “extremely distant” galaxies in this image. Foreground galaxies distort light and help magnify these distant objects.
The light from these galaxies has been traveling for billions of years, explained NASA administrator Bill Nelson. Specifically, you are looking at the SMACS 0723 galaxy cluster as it appeared about 4.6 billion years ago. Behind, however, are older galaxies.
“This first image from NASA’s James Webb Space Telescope is the deepest, sharpest infrared image in the distant universe to date. Known as Webb’s first deep field, this image from the SMACS 0723 galaxy cluster is full of detail.” , explains NASA in a statement. “Thousands of galaxies, including the faintest objects ever observed in the infrared, have appeared in Webb’s sight for the first time. This part of the immense universe covers a piece of sky about the size of a grain of sand. that someone has at arm’s length. on the ground “.
NASA calls this image “Webb’s first deep field.” It is an image of the galaxy cluster “SMACS 0723”. The mass of galaxies distorts and increases the galaxies furthest from the bottom. Credits: NASA / ESA / CSA / STScI
Spectrum of WASP-96 exoplanets b
Some of the most impressive observations from the Webb telescope will not come from any beautiful image. Using instruments called spectrometers, Webb can find out what the atmospheres of distant alien worlds are made of. (There may be a trillion or more exoplanets in our Milky Way galaxy alone.) Some planets, for example, may contain water, methane, and carbon dioxide, which could mean they are habitable worlds.
Webb’s first gas spectrum on an exoplanet comes from WASP-96 b, known as “Hot Jupiter”. It is a high-temperature gas giant that zooms around its star at tremendous speeds, taking only 3.4 days in a single orbit.
“NASA’s James Webb Space Telescope has captured the different signature of water, along with evidence of clouds and fog, in the atmosphere surrounding a giant planet of hot, inflated gas orbiting a distant Sun-like star.” , NASA explained. “The observation, which reveals the presence of gas-specific molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyze atmospheres in hundreds of light years away “.

The southern ring nebula
The southern ring nebula is a type of object called a “planetary nebula.” These are living shells of gas and dust ejected into space by a dying star. This well-known planetary nebula is about 2,000 light-years from us.
“Some stars keep the best for last,” NASA wrote. “The faintest star in the center of this scene has been sending rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that this star is covered in dust. “.

Stephan’s Quintet
The Stephan quintet is a well-known group of galaxies about 290 million light-years away. Four of them are relatively close to each other, “stuck in a cosmic dance of repeated close encounters,” NASA said.
“With its powerful infrared vision and extremely high space resolution, Webb shows details never seen before in this group of galaxies,” NASA explained. “Bright clusters of millions of young stars and starburst regions of fresh star births appreciate the image. Gas tails, dust and stars are removed from several of the galaxies due to gravitational interactions.”

The Carina Nebula
Nebulae are some of the most dazzling regions of space. They are giant clouds of dust and gas, like those formed after the explosion of a giant star. They are fertile ground for new stars to form. Webb captured a vision of the colossal Carina Nebula, located about 7,600 light-years away, a place where large stars have already formed.

“This landscape of bright star-stained ‘mountains’ and ‘valleys’ is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula,” NASA wrote. “Captured in infrared light by NASA’s new James Webb space telescope, this image reveals for the first time previously invisible areas of star birth.” The highest “peaks” you see here are about seven light-years high, the space agency added.
The observatory of deep space
The Webb telescope, a collaboration between NASA, the European Space Agency and the Canadian Space Agency, is designed to make unprecedented discoveries. “With this telescope, it’s very hard not to break records,” Thomas Zurbuchen, an astrophysicist and associate administrator at NASA for the agency’s Scientific Mission Management, said recently at a news conference.

Here’s how Webb will achieve incomparable things:
-
Giant Mirror: Webb’s light-capturing mirror is more than 21 feet in diameter. This is more than two and a half times larger than the mirror of the Hubble Space Telescope. Capturing more light allows Webb to see more distant ancient objects. The telescope will look at the stars and galaxies that formed more than 13 billion years ago, just a few hundred million years after the Big Bang.
“Let’s see the first stars and galaxies that formed,” Jean Creighton, astronomer and director of the Manfred Olson Planetarium at the University of Wisconsin-Milwaukee, told Mashable.
-
Infrared view: Unlike Hubble, which sees much of the light that is visible to us, Webb is primarily an infrared telescope, that is, it sees light in the infrared spectrum. This allows us to see the universe much more. Infrared has longer wavelengths than visible light, so light waves slide more efficiently through cosmic clouds; light does not collide as often or scatter through these densely packed particles. Ultimately, Webb’s infrared vision can penetrate sites that Hubble can’t.
“Raise the veil,” Creighton said.

Looking at distant exoplanets: the Webb telescope it carries specialized equipment, called spectrometers, which will revolutionize our understanding of these distant worlds. Instruments can decipher which molecules (such as water, carbon dioxide, and methane) exist in the atmospheres of distant exoplanets, whether they are gas giants or smaller rocky worlds. Webb will examine the exoplanets of the Milky Way. Who knows what we will find.
“We could learn things we never thought about,” Mercedes Lopez-Morales, an exoplanet researcher and astrophysicist at the Center for Astrophysics-Harvard & Smithsonian, told Mashable.
