NASA Reveals Webb Telescope’s First Images of Unseen Universe

The dawn of a new era in astronomy has begun as the world gets its first look at the full capabilities of NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and CSA (Canadian Space Agency). All of the telescope’s first full-color images and spectroscopic data, which uncover a collection of cosmic features that have remained elusive until now, released Tuesday, are available at:

“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,” said NASA Administrator Bill Nelson. “These images, including the deepest 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.

“The Webb team’s incredible success is a reflection of what NASA does best. We take dreams and turn them into reality for the benefit of humanity. I can’t wait to see the discoveries that we uncover – the team is just getting started!”

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 exoplanets to the most distant observable galaxies in the early universe.

“This is a singular and historic moment,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “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.” 

“We are elated to celebrate this extraordinary day with the world,” said Greg Robinson, Webb program director at NASA Headquarters. “The beautiful diversity and incredible detail of the Webb telescope’s images and data will have a profound impact on our understanding of the universe and inspire us to dream big.” 

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

• SMACS 0723: Webb has delivered the deepest and sharpest infrared image of the distant universe so far – and in only 12.5 hours. 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. This image only scratches the surface of Webb’s capabilities in studying deep fields and tracing galaxies back to the beginning of cosmic time.
• 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 other planetary atmospheres 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 powerful 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 unprecedented 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.

“Absolutely thrilling!” said John Mather, Webb senior project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The equipment is working perfectly, and nature is full of surprising beauty. Congratulations and thanks to our worldwide teams that made it possible.”

The release of Webb’s first images and spectra kicks off the beginning of Webb’s science operations, 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.

“Today is the start of something truly revolutionary in astronomical research. The universe will never look the same again – it will appear grander, more dynamic, and more detailed than ever before,” said Kenneth Sembach, Director at STScI. “To follow these observations as they were meticulously planned, performed, and processed by our teams for today’s release was an exciting and rewarding experience. I am thrilled that our staff here at STScI are at the heart of enabling and conducting forefront astronomical research with this incredible new observatory.”

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.

The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

NASA Headquarters oversees the mission for the agency’s Science Mission Directorate. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages Webb for the agency and oversees work on the mission performed by the Space Telescope Science Institute, Northrop Grumman, and other mission partners. In addition to Goddard, several NASA centers contributed to the project, including the agency’s Johnson Space Center in Houston, Jet Propulsion Laboratory in Southern California, Marshall Space Flight Center in Huntsville, Alabama, Ames Research Center in California’s Silicon Valley, and others.
