Discover the science mission of NASA’s James Webb Space Telescope (JWST), from exoplanet atmospheres to the first light in the universe—and more!

Jan 24, 2025 · The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system.

The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, …

Mar 7, 2024 · Taken during instrument calibration, this image helped test Webb’s ability to dig up galactic “fossils.” Ancient galaxies are so far that as space expands, their light has stretched into infrared wavelengths — Webb’s specialty.

What is the James Webb Space Telescope looking at now? Where is this target in the sky? When is the next observation happening? How is Webb collecting the data? Who is leading the investigation? Why are scientists interested in this target?

The James Webb Space Telescope (sometimes called Webb or JWST) is a large infrared telescope with a 6.5-meter primary mirror. Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide.

Jan 24, 2025 · In December 2022, less than six months after commencing science operations, NASA’s James Webb Space Telescope revealed something never seen before: numerous red objects that appear small on the sky, which scientists soon called “little red dots” (LRDs).

Aug 22, 2024 · A brief overview of the James Webb Space Telescope mission from its construction, launch, and complex unfolding, to the incredible science it achieves.

3 days ago · The James Webb Space Telescope (JWST) is an observatory that uses infrared light to capture images of the way the universe looked approximately 200 million years after the big bang. Currently, the James Webb Space Telescope is the largest telescope orbiting in space with 18 mirror segments and totaling approximately 6,200 kg in mass.

Nov 20, 2023 · The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain.
