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

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, distant, or faint for the Hubble Space Telescope. [9] This enables investigations across many fields of astronomy and cosmology, …

2025年1月21日 · NASA’s James Webb Space Telescope has revealed details of the Southern Ring planetary nebula that were previously hidden from astronomers.... NASA’s James Webb …

2025年1月24日 · 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.

2025年1月14日 · The telescope will be able to capture images of some of the first galaxies ever formed. It will also be able to observe objects in our solar system from Mars outward, look inside dust clouds to see where new stars and planets are forming and examine the atmospheres of planets orbiting other stars.

2024年8月22日 · NASA’s James Webb Space Telescope, or Webb, emerged from Chamber A at NASA’s Johnson Space Center in Houston on Dec. 1, 2017. With unprecedented infrared sensitivity, it will peer back in time over 13.5 billion years to see the first galaxies born after the Big Bang. Webb is the largest telescope ever placed in space.

2024年8月22日 · The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity.

2024年8月22日 · The James Webb Space Telescope, also called Webb or JWST, is a large, space-based observatory, optimized for infrared wavelengths, which complements and extends the discoveries of the Hubble Space Telescope.

Webb launched on the sun-facing side of the Earth and travels on a slightly curved path so Webb's "distance travelled" is greater than its altitude. Webb passing the Moon's altitude is a good example of the difference, when Webb reached the altitude (a) of the Moon at a time of launch + ~2.5 days, Webb had already travelled a distance (d ...

The James Webb Space Telescope (sometimes called JWST or Webb) is a large infrared telescope with a 6.5-meter primary mirror. The telescope was launched on an Ariane 5 rocket from French Guiana in December 2021.
