ALT A fossilized skeleton of a large prehistoric mammal, paleoparadoxia, is displayed in a suspended running position. The bones are arranged to suggest motion, with the background depicting an aquatic theme.
ALT A complex scientific apparatus featuring metallic components, wires, and attachments is set against a backdrop illuminated with green lighting. An encased fusion fuel target sits in an experimental chamber in SLAC National Accelerator Laboratory’s Sector 10 laser lab. Once the chamber is vacuum-sealed and cooled to extreme temperatures, researchers will image the target with optical laser pulses to reveal critical details about its structure and durability. These insights will help researchers advance target design for future inertial fusion energy processes. (Jacqueline Ramseyer Orrell/SLAC National Accelerator Laboratory)
ALT SLAC scientist Meriame Berboucha mounts a fusion fuel target in an experimental support structure at SLAC National Accelerator Laboratory’s Sector 10 laser lab. Researchers image these targets with optical laser pulses to reveal critical details about their structure and durability to help researchers advance target design for future inertial fusion energy processes.

ALT A person with gloved hands holds two intricate metal laboratory instruments, component parts of scientific equipment, against a blurred background. These experimental support structures hold sand-grain-sized fusion targets bearing deuterium fuel. At SLAC National Accelerator Laboratory’s Sector 10 laser lab, researchers image these targets with optical laser pulses to reveal critical details about their structure and durability to help researchers advance target design for future inertial fusion energy processes.

ALT A modern building with large windows and a red roof features a banner in front of it. The banner reads "Bay Area Light Sources Joint Users' Meeting, 20-25 September, 2026, A First-Ever Collaboration," and includes logos for Advanced Light Source, LCLS, and SSRL. An American flag is visible nearby. Credit: Lara Streiff/SLAC

ALT A dense field of countless pinpoint stars fills the frame against the deep black of space, creating a fine, grainy texture like fine sand spread across a smooth table. Dozens of particularly bright stars in blue, yellow, and orange glitter across the scene like jewels. Wispy, grayish clouds of galactic dust drift across the center and right sides of the image, appearing soft and powder-like against the dark background. Scattered throughout the entire scene are stars and faint objects in shades of blue, yellow, and red. Some appear as sharp, solid points, while others are soft, diffuse smudges. Zooming in reveals that many of these tiny, faint smudges scattered between the stars are actually distant galaxies, varying from smooth, pebble-like blobs to faint, stretched lines.
ALT Golden spiral galaxy with blueish spiral arms in a dense star field. Numerous orange and blue stars dot the dark sky, with a bright bluish star left of center and faint background galaxies scattered throughout.
ALT A wide, panoramic view of a dense field of pinpoint stars filling the entire frame like fine dust. A white square notes a specific galaxy near upper center. Wispy, grayish-brown clouds of galactic cirrus drift across the scene, creating a subtle, patchy texture over the dark background. Several brighter stars stand out, most notably a large, brilliant blue star on the upper right surrounded by a soft glowing halo, along with a few other scattered bright blue and warm orange stars.
