On July 12, the world received its first look at the full capabilities of NASA’s (Washington, D.C., U.S.) James Webb Space Telescope (JWST), a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency). Shown above are some of the telescope’s first full-color images and spectroscopic data, which uncover a collection of cosmic features elusive until now. The full set .

“Today, we present humanity with a groundbreaking new view of the cosmos from the James Webb Space Telescope — a view the world has never seen before,” NASA Administrator Bill Nelson says. “These images, including the deepest infrared view of our universe that has ever been taken, show us how Webb will help to uncover the answers to questions we don’t even yet know to ask; questions that will help us better understand our universe and humanity’s place within it.”

NASA explores the unknown in space for the benefit of all, and Webb’s first observations tell the story of the hidden universe through every phase of cosmic history — from neighboring planets outside our solar system, known as exoplanets, to the most distant observable galaxies in the early universe. 

“This is a singular and historic moment,” Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate, adds. “It took decades of drive and perseverance to get us here, and I am immensely proud of the Webb team. These first images show us how much we can accomplish when we come together behind a shared goal, to solve the cosmic mysteries that connect us all. It’s a stunning glimpse of the insights yet to come.”

Webb’s first observations were selected by a group of representatives from NASA, ESA, CSA and the Space Telescope Science Institute (Baltimore, Md., U.S.). They reveal the capabilities of all four of Webb’s state-of-the-art :

• SMACS 0723: Webb has reportedly delivered the deepest and sharpest infrared image of the distant universe so far — and in only 12.5 hours. For a person standing on Earth looking up, the field of view for this new image, a color composite of multiple exposures each about two hours long, is approximately the size of a grain of sand held at arm’s length. This deep field uses a lensing galaxy cluster to find some of the most distant galaxies ever detected, according to NASA. This image only scratches the surface of Webb’s capabilities.
• WASP-96b (spectrum): Webb’s detailed observation of this hot, puffy planet outside our solar system reveals the clear signature of water, along with evidence of haze and clouds that previous studies of this planet did not detect. With Webb’s first detection of water in the atmosphere of an exoplanet, it will now set out to study hundreds of other systems to understand what  are made of.
• Southern Ring Nebula: This planetary nebula, an expanding cloud of gas that surrounds a dying star, is approximately 2,000 light years away. Here, Webb’s infrared eyes bring a second dying star into full view for the first time. From birth to death as a planetary nebula, Webb can explore the expelling shells of dust and gas of aging stars that may one day become a new star or planet.
• Stephan’s Quintet: Webb’s view of this compact group of galaxies, located in the constellation Pegasus, pierced through the shroud of dust surrounding the center of one galaxy, to reveal the velocity and composition of the gas near its supermassive black hole. Now, scientists can get a rare look, in detail, at how interacting galaxies are triggering star formation in each other and how the gas in these galaxies is being disturbed.
• Carina Nebula: Webb’s look at the “Cosmic Cliffs” in the Carina Nebula unveils the earliest, rapid phases of star formation that were previously hidden. Looking at this star-forming region in the southern constellation Carina, as well as others like it, Webb can see newly forming stars and study the gas and dust that made them.

The release of Webb’s first images and spectra kicks off the beginning of , where astronomers around the world will have their chance to observe anything from objects within our solar system to the early universe using Webb’s four instruments.

The James Webb Space Telescope launched Dec. 25, 2021 on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America. After completing a complex deployment sequence in space, Webb underwent months of commissioning where its mirrors were aligned, and its instruments were calibrated to its space environment and prepared for science.
