This gas cell is a key component of a compact wakefield laser accelerator developed at The University of Texas at Austin. Inside, an extremely powerful laser strikes helium gas, heats it into a plasma and creates waves that kick electrons from the gas out in a high-energy electron beam.

The second- and fourth-most distant galaxies ever seen (UNCOVER z-13 and UNCOVER z-12) have been confirmed using the James Webb Space Telescope’s Near-Infrared Camera (NIRCam). The galaxies are located in Pandora’s Cluster (Abell 2744), show here as near-infrared wavelengths of light that have been translated to visible-light colors. The scale of the main cluster image is labelled in arcseconds, which is a measure of angular distance in the sky. The circles on the black-and-white images, showing the galaxies in the NIRCam-F277W filter band onboard JWST, indicate an aperture size of 0.32 arcsec.

Panchromatic view of MACS0416, a galaxy cluster about 4.3 billion light-years from Earth. The image was created by combining infrared observations from NASA’s James Webb Space Telescope with visible-light data from NASA’s Hubble Space Telescope. The resulting prismatic panorama of blues and reds give clues to the distances of the galaxies.
