Very interesting article, but can you please stop refering to James Webb telescope as "NASA's James Webb Space Telescope"?
It was built by a consortium of space agencies and research centers all around the world, including European Space Agency, Japan, Canada and many others.
Using its Near-Infrared Camera (NIRCam), NASA's James Webb Space Telescope peered into a region for a total of about 255 hours. This exceptionally long observation allowed astronomers to trace dark matter by studying how its gravity distorts and influences the light from distant galaxies.
