The James Webb Space Telescope

See a stunning new view of Neptune’s rings and oddball moon Triton from the James Webb Space Telescope

The James Webb Space Telescope’s snapshots of a giant world orbiting another star show that the observatory is performing even better than expected and that its best exoplanet images are yet to come

The James Webb Space Telescope’s first images of the distant universe shocked astronomers. Is the discovery of unimaginably distant galaxies a mirage or a revolution?

Scientific American co-presents a discussion about the past, present and future of the James Webb Space Telescope

Webb sees through dust and gas into regions out of reach of optical telescopes such as Hubble, revealing new galaxy views

Astronomers and the public alike are delighting in the glittering depths of the universe revealed by the James Webb Space Telescope

Deep-field images of “empty” regions of the sky from JWST and other space telescopes are revealing more of the universe than we ever thought possible

Breathtaking pictures that include the deepest-ever infrared view of ancient galaxies offer a preview of the spectacular science in store for the most powerful space observatory in history

Decades of work, $10 billion in spending and nearly 14 billion years of cosmic history have brought us to this moment: the first science from the largest and most powerful observatory ever built.

A new galaxy-packed picture from the James Webb Space Telescope offers a chance to rekindle our wonder about the universe

Jane Rigby, Webb’s operations project scientist, discusses how NASA plans to wring as much science as possible from the $10-billion observatory

Space agency officials promise to deliver geology results from worlds dozens of light-years away

E-mailed exchanges show the space agency’s internal struggle to address pleas to change the controversial name of its latest, greatest observatory

With its mirrors now focused, the observatory’s science instruments are now being readied for work

The ambitious observatory has arrived at its home—near a gravitationally stable spot called L2—for a premier view of the universe

The observatory’s unprecedented infrared measurements might at last bridge a growing rift between astronomers over how fast the universe is expanding

The observatory has flawlessly unfurled its mirrors and sunshield—although more steps are needed before the science can begin

The successful unfurling of the five-layered, tennis court-sized assemblage is a major milestone for the new observatory

NASA’s James Webb Space Telescope will travel to a special spot where the gravity from Earth and the sun is balanced

After years of delay, the most ambitious observatory ever built has at last left Earth. It now faces a high-stakes series of deployments in deep space

The long-delayed successor to the Hubble Space Telescope is set to take flight in December

The observatory must complete about 50 major deployments after liftoff

Before it can study the first stars and galaxies, the observatory must endure a sea voyage, a rocket launch and an all-or-nothing deployment sequence in deep space

From more than 1,000 proposals, the scientists that hoped to perform the observatory’s historic first studies now know their fate
