JWST for Scientists

The James Webb Space Telescope (JWST), NASA's flagship infrared observatory, developed in partnership with ESA and CSA, successfully launched on December 25, 2021. After deploying in space and alignment and calibration of the mirrors and instruments, JWST began science operations in July 2022.

Accessible to the worldwide scientific community, JWST offers scientists the opportunity to observe galaxy evolution, the formation of stars and planets, exoplanetary systems, and our own solar system, in ways never before possible. This website offers scientists information on proposing for time on JWST as well as the capabilities of the observatory's instruments and modes, data analysis tools and software, and news and events.

NASA Webb Pushes Boundaries of Observable Universe Closer to Big Bang

$A wide field of view showing deep space, dotted with many small galaxies and a few foreground stars that display six diffraction spikes.$
NASA Webb Finds Young Sun-Like Star Forging, Spewing Common Crystals

January 21, 2026

$A portion of the Serpens Nebula. A young star-forming region is filled with wispy orange, red, and blue layers of gas and dust. The upper left corner of the image is filled with mostly orange dust, and within that orange dust, there are several small red plumes of gas that extend from the top left to the bottom right at the same angle. At center-left is a larger star that is circled. This star has Webb’s signature diffraction spikes, but along the right also has an arc of white, with the circular edge starting at the center of the star. Mostly blue gas fills the bottom-center. The gas to the right is a darker orange. Small points of light are sprinkled across the field. The brightest sources have extensive eight-pointed diffraction spikes.$
Intricacies of Helix Nebula Revealed With NASA's Webb

January 20, 2026

$A closeup of a small section of the Helix Nebula, an expanding shell of gas and dust. Thousands of orange and gold comet-like pillars stream upward from the bottom, like thin liquid blown up a sheet of glass. These pillars are around the circumference of the arced shell, which forms a partial orange semi-circle at the bottom. The pillars are more numerous and denser at the bottom, and darker red. They fade to orange and then yellow in the arc. In the top two-thirds, they are thinner and more golden, and it’s easier to see the black background of space. Several bright blue stars, some with diffraction spikes, are scattered throughout. A few larger stars are on the right side.$
