JWST

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.

The James Webb Space Telescope has sustained a micrometeoroid impact to one of its mirror segments. While larger than the impacts anticipated during ground testing, the telescope should still be able to perform the tasks it was designed for.

The James Webb Space Telescope has snapped its first in-focus image. With this milestone, the telescope is now set to meet or even exceed its original science goals. It was also recently spotted by another spacecraft in the area.

The James Webb Space Telescope has taken its first images of space. What looks like a smeared starfield is actually the same star snapped 18 times, as the mirror segments try to align to focus on the star. The craft also took a selfie of its mirrors.

A new study has projected that a future NASA telescope could be capable of discovering up to 1,400 new worlds. The orbital telescope, which has been nicknamed WFIRST, will build on the legacy of earlier missions to answer fundamental questions surrounding the nature of the universe.
