Webb data used to map dark matter across a 0.54 sq. degree field in Sextans

NASA’s James Webb Space Telescope observed a 0.54 square degree region in the constellation Sextans and, using those data, researchers produced a dark matter map overlaid on an image containing nearly 800,000 galaxies. The map shows dark matter in blue, with brighter blue indicating higher dark matter

Webb captures detailed structures and chemistry in the Helix Nebula

NASA’s James Webb Space Telescope has produced a high-resolution near-infrared image of a portion of the Helix Nebula that highlights comet-like knots, fierce stellar winds and layers of gas being shed by a dying star. Webb’s NIRCam image shows pillar-like features with extended tails tracing the inner edge
