The deepest view of the universe ever taken, captured in less than a day
In July 2022, humanity turned its deepest eye yet toward the beginning of time. President Biden unveiled the first images from the James Webb Space Telescope — a machine decades in the making — revealing thousands of ancient galaxies that no instrument had ever been able to find. In a single infrared frame, light that had traveled billions of years finally arrived, offering not just a picture of the cosmos, but a mirror held up to our own capacity for wonder and long patience.
- A telescope billions of dollars in the making delivered its first image — and it surpassed every expectation, showing thousands of galaxies in a single frame captured in less than a day.
- The image of galaxy cluster SMACS 0723 used gravitational lensing to bend and magnify light from objects so distant and ancient they had been invisible to every previous telescope in history.
- President Biden, Vice President Harris, and NASA leadership framed the moment as a triumph of American science and engineering, carefully staging the reveal to maximize its global impact.
- Four more targets — a stellar nursery, a dying star's gas cloud, a distant exoplanet, and a gravitationally entangled galaxy group — were queued for release the following day, each promising to rewrite a different chapter of cosmic understanding.
- Webb's infrared vision cuts through the dust and fog that blocked older telescopes, opening an entirely new window onto the universe's earliest and most obscured structures.
On a Monday in July, President Biden stood before the nation to unveil the first images from the James Webb Space Telescope — humanity's deepest look yet into the early universe. The inaugural image centered on SMACS 0723, a galaxy cluster whose immense gravity bends and magnifies light from objects far behind it. Through this phenomenon, known as gravitational lensing, Webb revealed thousands of galaxies, some so ancient and faint that no telescope in history had detected them. The entire image had been captured in less than a day.
Vice President Kamala Harris, who chairs the National Space Council, called Webb one of humanity's great engineering achievements. NASA administrator Bill Nelson described it simply as the deepest view of the universe ever taken. The unveiling was carefully staged: a first image on Monday, followed by a full release event on Tuesday, July 12, with opening remarks, a live broadcast, and a news conference.
Four additional cosmic targets were already announced. The Carina Nebula, a stellar nursery 7,600 light-years away, would show stars being born. The exoplanet WASP-96b, 1,150 light-years distant, would offer new atmospheric data. The Southern Ring Nebula would reveal a dying star shedding its outer layers. And Stephan's Quintet — five galaxies locked in gravitational interaction since their discovery in 1787 — would illuminate how galaxies shape and reshape one another over millions of years.
What made all of this possible was Webb's infrared vision. Unlike its predecessors, the telescope sees through the dust clouds and cosmic fog that hide the universe's oldest structures. After decades of development and billions of dollars invested, Webb had arrived — and in its first weeks, it was already changing what we thought we could see.
On a Monday in July, President Biden stood before the nation and called it a historic moment. He was about to release the first images ever captured by the James Webb Space Telescope—a machine that had taken humanity's deepest look into the early universe. The pictures showed something that had never been seen before: thousands of galaxies, some so old and faint that no telescope in history had been able to find them.
The inaugural image focused on a region called SMACS 0723, a massive cluster of galaxies that acts like a cosmic lens. The gravity of these clusters bends light from objects far behind them, magnifying what would otherwise be invisible. This phenomenon, called gravitational lensing, allowed Webb to peer deeper into space and further back in time than any instrument before it. In a single frame, the telescope revealed galaxies that existed when the universe was still young, their light having traveled billions of years to reach us.
Biden spoke of American scientific leadership and the power of the technology at work. Vice President Kamala Harris, who chairs the National Space Council, called the telescope one of humanity's great engineering achievements. NASA administrator Bill Nelson described the image as the deepest view of the universe ever taken. What made the accomplishment even more striking was the speed: the entire image had been captured in less than a day of observation.
The unveiling was carefully choreographed. The first image dropped on Monday, but NASA had scheduled a full release event for Tuesday, July 12. Opening remarks would begin at 9:45 a.m. Eastern time, with the image broadcast starting at 10:30 a.m., followed by a news conference at 12:30 p.m. The agency had already teased what was coming: four additional targets that would reshape how we understand the cosmos.
The Carina Nebula, located 7,600 light-years away, is a stellar nursery where stars are born. It ranks among the largest and brightest nebulae visible in the sky, home to stars far more massive than our sun. WASP-96b, discovered in 2014 and sitting 1,150 light-years from Earth, is an exoplanet with half Jupiter's mass that orbits its star every 3.4 days. The Southern Ring Nebula, also known as the Eight-Burst, lies 2,000 light-years away and shows an expanding cloud of gas surrounding a dying star.
Perhaps most intriguing was Stephan's Quintet, a compact group of five galaxies first identified in 1787 and located 290 million light-years away in the constellation Pegasus. Four of the five galaxies in this group are locked in what NASA described as a cosmic dance of repeated close encounters, their gravitational interactions playing out across millions of years. Webb's view would reveal the mechanics of how galaxies interact and shape one another.
The release of these images marked a turning point. For decades, astronomers had relied on telescopes that could only see visible light. Webb operates in the infrared spectrum, allowing it to penetrate dust clouds and see through the cosmic fog that obscures the oldest galaxies. The telescope had cost billions of dollars and taken years to develop and launch. Now, in its first weeks of operation, it was delivering on its promise to fundamentally change how we see the universe.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that these galaxies are so old and faint?
Because they're showing us the universe as it was only a few hundred million years after the Big Bang. We've never seen that far back before. These aren't just pretty pictures—they're evidence of how the first galaxies formed.
And the gravitational lensing—that's not a flaw in the image, it's actually helping us see more?
Exactly. Those massive galaxy clusters in front act like a magnifying glass. Without them, we couldn't see the faintest galaxies at all. Nature is doing the heavy lifting for us.
Why did it take less than a day to capture something this deep?
Webb is extraordinarily sensitive. It collects infrared light that other telescopes can't detect. In just a few hours of staring at one small patch of sky, it gathers enough photons to build an image of thousands of galaxies.
What changes now that we have these images?
We can start answering questions we've had for decades. How did the first galaxies form? How quickly did they grow? What was the universe like in its infancy? These images are the beginning of those answers.
Is this the end of what Webb will show us, or just the start?
Just the start. This is one region of sky. Webb will spend years observing different parts of the universe, different types of objects. We're looking at the opening chapter of a very long book.
