  • A James Webb Space Telescope deep field image showing hundreds of distant galaxies scattered across a black background in a range of shapes — spirals, ellipticals, and elongated streaks — in colors from white and blue to orange and red. A large, detailed barred spiral galaxy with a bright white core and faint blue spiral arms dominates the center-left of the frame. Several foreground stars display the distinctive six-pointed diffraction spikes characteristic of JWST imagery.

    JWST studies a supernova near the dawn of time

  • A dense web of thin blue-purple filaments spans the entire frame, threading through deep red and maroon voids to converge on a blazing central cluster of orange, yellow, and white gas. Scattered across the field, smaller orange and gold clumps glow at the intersections of the filaments. The overall effect resembles a three-dimensional cosmic spiderweb
    Cosmology, Features

    Untangling the cosmic web

  • A grid of eight distinct square panels are arranged in two rows of four against a black background. Each panel shows a bright, yellowish-orange core surrounded by thin, glowing blue rings or partial arcs that encircle the central light. Text labels containing long strings of numbers appear at the bottom of each square panel, with a larger informational title section situated underneath the entire grid.

    June 9, 1988: First image of an Einstein ring

  • A 360-degree panoramic view of the Milky Way galaxy stretching horizontally across the frame as a bright, glowing band of stars and dust. The galactic center is visible near the middle, dense with warm orange and brown dust lanes and bright star clusters. The surrounding sky is deep black, dotted with individual stars and a few faint nebulae and satellite galaxies visible in the lower portion of the image.
