The objects are all at various distances set against the black background of space. Most galaxies appear as tiny fuzzy ovals in white, orange, or red. A slightly larger, very bright, light blue spiral galaxy is at center. To its immediate left and right are two large bright pink splotches representing X-rays. The right pink area has a rounded nose facing right, where it is darker pink, and fades to the left as a triangular shape. This is referred to as the Bullet. To the far left and far right, next to the pink regions, are two blue regions representing dark matter mass. The left blue region is a large, long oval at an angle. The blue region at right is a far smaller oval.\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" loading=\"eager\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png 11235w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=300,126 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=768,322 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=1024,430 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=1536,644 1536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=2048,859 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=400,168 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=600,252 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=900,378 900w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=1200,503 1200w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2025\/09\/54624223606-8a775fd547-o.png?resize=2000,839 2000w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\">\n<div class=\"hds-credits\">NASA, ESA, CSA, STScI, CXC<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n<p>This image released on June 30, 2025, combines data from NASA\u2019s James Webb Space Telescope and NASA\u2019s Chandra X-ray Observatory to visualize dark matter.
