The James Webb Space Telescope is nearing completion of the first phase of the months-long process of aligning the observatory’s primary mirror using the Near Infrared Camera (NIRCam) instrument.

A look at the James Webb Space Telescope, its mission and the incredible technological challenge this mission presents. The Webb is now in the final stages of testing in the U.S. before being shipped to French Guiana ahead of its expected launch from there at the end of October, 2021.

We don’t yet know what the James Webb Space Telescope will uncover. Will we get answers? Will we have more questions? One thing’s certain: The story of us is a never-ending quest for knowledge.

Astronomers are combing through fresh data from the James Webb Space Telescope in a never-ending quest to find ever-more-distant galaxies. However, the observatory is still studying a variety of objects, from insanely detailed images of Jupiter to the most distant known star.

A star nursery 1,350 light years away toward the equatorial constellation of Orion has been captured for the first time by NASA. The Orion Nebula is a region that is similar to the region where the Solar System originated 4.5 billion years ago. Since the Orion nebula's newborn stars are being forme...

Watch the launch of the James Webb Space Telescope—the most powerful space telescope ever made. This mission is scheduled to lift off at 7:20 a.m. EST (12:20 UTC), Dec. 25, 2021, aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana. With revolutionary technology, Webb will observe a pa

Jupiter has a lot going on, with massive storms, intense winds, auroras, and severe temperature and pressure extremes. The James Webb Space Telescope of NASA has now taken fresh images of the planet. Webb's Jupiter observations will provide scientists with much more information about Jupiter's inner...

Astronomers using the James Webb Space Telescope have discovered a galaxy that could make us revise our cosmology models. It's a galaxy named CEERS-1749, which could be the farthest galaxy to date. Astronomers have nicknamed this galaxy Schrodinger's galaxy because it could be at two places at once....

The first image from the James Webb Space Telescope was released at an event led by President Biden, Vice President Harris and NASA officials. Mr. Biden said the telescope, the most powerful ever built, "symbolizes the relentless spirit of American ingenuity." Watch the event here.

A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe.

SpaceX launched the European Space Agency’s Euclid observatory toward its ultimate destination 1.5 million kilometers away, the Webb Space Telescope’s neighborhood.
