The James Webb Space Telescope keeps challenging our models of the universe, seeing farther away than ever before. Now it’s discovered “impossibly” gigantic galaxies that contain more mass than was thought to exist in the whole universe at that time.

The James Webb Space Telescope has been used to confirm the existence of an exoplanet for the first time. Known as LHS 475 b, this Earth-sized world is a cosmic stone’s-throw away and is likely the first of many planet discoveries by Webb.

The James Webb Space Telescope is probing greater depths of space and time than other observatories. Now it's discovered galaxies with a structure like our own Milky Way 11 billion light-years away, challenging our understanding of galaxy formation.

In 2022, decades of work finally came to fruition as the James Webb Space Telescope focused its powerful eyes on the universe. From distant galaxies to our nearby neighbors, let’s look back at some of the most impressive images captured so far.

The James Webb Space Telescope has provided the most detailed look at an exoplanet atmosphere ever. Studying data from four instruments astronomers compiled a complete molecular and chemical profile of the planet, including signs of active chemistry.

The James Webb Space Telescope has snapped some incredible images in its short career, but this new one is a doozy. The spacecraft has now taken images of the iconic Pillars of Creation, revealing new details and giving a peek behind the cloudy curtain.

The James Webb Space Telescope has snapped its first direct images of an exoplanet. With its uniquely powerful instruments, Webb captures details that other observatories miss, which will help us understand these distant worlds better.

The James Webb Space Telescope has clearly detected carbon dioxide in the atmosphere of an exoplanet for the first time. The find marks a milestone for the telescope’s goal of analyzing the air of distant planets to aid the search for alien life.

The James Webb Space Telescope keeps breaking its own records for peering deeper into space and time. It's now detected a galaxy candidate about 35 billion light-years from Earth, which if confirmed would make it the most distant galaxy ever found.

James Webb Space Telescope's historic first images showed a galaxy cluster billions of light-years away, but now it’s turned its sights on something much closer to home. NASA has released infrared images of Jupiter used to test Webb's instruments.

If you’ve seen the first images from the James Webb Space Telescope this week, you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help this new telescope make discoveries?

By now you’ve no doubt seen the first batch of images from NASA’s powerful new James Webb Space Telescope. But the scope of the achievement is hard to appreciate without context, so here they are side-by-side with Hubble’s views of the same regions.
