Researchers Submit Record Number of Ambitious Proposals for Webb's Fifth Year of Science
November 12, 2025Illustration of the James Webb Space Telescope at the right with its gold, hexagon-shaped primary mirror and multi-layer sunshield. At left is a representation of part of its 18 primary mirror segments, which takes up about two-thirds of the view. Each segment is outlined in yellow and contains a different Webb image, artist’s concept, or spectrum (graph). The images display dying stars puffing off layers of gas and dust, spiral galaxies, planets, and deep fields of space spattered with fuzzy white galaxies. Three yellow, orange, and red wavy lines appear atop everything else, running left to right. The backdrop shows filaments of red gas and dust, white and blue stars, and distant galaxies, all against the black background of space. -
'Coast' Through the Cosmos with Webb at Dulles International Airport
November 06, 2025Closeup of Dulles airport hallway shows a large-scale James Webb Space Telescope image on the left, which takes up half of the view. Text on the image reads, Where Stars Form, Serpens Nebula: Star-Forming Region. The image shows a young star-forming region that is filled with wispy orange, red, and blue layers of gas and dust. The center is filled with mostly blue gas. Small points of light are sprinkled across the field. Beyond this in the same hall are several additional large-scale Webb images, each showing unique, colorful cosmic objects. -
Aging White Dwarf Still Consuming Its Planetary System
October 22, 2025At image center is a small, white star against a gray background. It is surrounded by a large translucent disk with rings and gaps that extends from upper left to lower right. In the foreground, irregular chunky rocks are floating in space along the bottom of the frame. A stream of material extends from lower right toward the central star. The words, artist's concept are at lower left.
