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.

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).

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.

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.

View the First Images Gallery where the James Webb Space Telescope's first color images and spectroscopic data showcase the telescope's full capabilities.

Aug 22, 2024 · The James Webb Space Telescope is not in orbit around the Earth, like the Hubble Space Telescope is – it actually orbits the Sun, 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2. What is special about this orbit is that it lets the telescope stay in line with the Earth as it moves ...
