It spans just about 60 light-years across, which is a veritable pinprick on the entire sky. The underlying image contains lower-, medium-, and higher-energy X-rays in red, green, and blue respectively. The annotations on the image show where Chandra has detected over 3,300 individual sources in this field of view over a 22-year timeframe.\t\t\t\t\t\t<\/div>\n<p>\t\t\t\t\t\t<!-- File List --><\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<p>Within the CSC, there is a wealth of information gleaned from the Chandra observations \u2014 from precise positions on the sky to information about the the X-ray energies detected. This allows scientists using other telescopes \u2014 both on the ground and in space including NASA\u2019s James Webb and Hubble Space Telescopes \u2014 to combine this unique X-ray data with information from other types of light.<\/p>\n<p>The richness of the Chandra Source Catalog is illustrated in a new image of the Galactic Center, the region around the supermassive black hole at the center of the Milky Way galaxy called Sagittarius A*. In this image that spans just about 60&nbsp;<a href=\"https:\/\/chandra.si.edu\/photo\/cosmic_distance.html\" rel=\"noopener\">light-years<\/a>&nbsp;across, a veritable pinprick on the entire sky, Chandra has detected over 3,300 individual sources that emit X-rays. This image is the sum of 86 observations added together, representing over three million seconds of Chandra observing time.<\/p>\n<p>Another new representation of the vast scope of the Chanda Source Catalog is found in a just-released sonification, the translation of astronomical data into sound. This sonification encompasses the new map that includes 22 years of Chandra observations across the sky, beginning from its launch through its observations in 2021. Because many X-ray sources have been observed multiple times over the life of the Chandra mission, this sonification represents those repeat X-ray sightings over time through different notes.<\/p>\n<div id=\"\" class=\"width-full maxw-full margin-left-auto margin-right-auto hds-media-align-inline hds-module wp-block-nasa-blocks-video\">\n<div class=\"hds-cover-wrapper width-full maxw-full flex-column\">\n<div class=\"hds-video-container width-full embed-container\"><video title=\"Chandra Source Catalog Sonification\" id=\"nasa-plus-C9zbc\" class=\"video-js video-player vjs-fluid width-full\" data-setup='{\"controls\":true,\"preload\":\"auto\",\"plugins\":{\"mux\":{\"debug\":false,\"data\":{\"env_key\":\"91nns8oppqdfqc44lgo4b1gni\",\"player_name\":\"www.nasa.gov Player\",\"video_name\":\"Chandra Source Catalog Sonification\"}}}}'  ><source src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2026\/01\/csc-sonification.mp4\" type=\"video\/mp4\"><p class=\"vjs-no-js\">To view this video please enable JavaScript, and consider upgrading to a web browser that<br \/>\n\t\t\t\t\t<a href=\"https:\/\/videojs.com\/html5-video-support\/\"  rel=\"noopener\">supports HTML5 video<\/a><\/p><\/video><\/div>\n<\/div>\n<div class=\"hds-media-caption hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\">\n<div>Chandra Source Catalog Sonification.<\/div>\n<\/div>\n<div class=\"hds-credits\">\n<div>NASA\/CXC\/SAO\/K.Arcand, SYSTEM Sounds (M.

A circle appears at the position of each detection and the size of the circle is determined by the number of detections in that location over time. A year counter appears at the top of the frame. Since Chandra continues to be fully operational, the text changes to \u201c\u2026 and beyond\u201d after 2021 as the telescope continues to collect observations. During the video, a collage of images produced by Chandra fades in as a background.

The image is dominated by burnt orange, deep gold and blue hues, with a sprinkling of rich green. The area looks both intricate and full, with a dense population of tiny dots, along with larger clumps and diffuse areas and nebulous areas peeking through.<\/p>\n<p>At the center of the image, there is a bright, lumpy area in pale gold showing the intense X-ray radiation emanating from the Sagittarius A* black hole. In the surrounding area, there are more smaller lumps layered throughout, feathering out to a large almost butterfly shape filling much of the screen. The image appears textured, like dozens of blue and orange glow worms are paused in their wriggling.<\/p>\n<p>The image offers an unprecedented view of lobes of hot gas extending for a dozen light years on either side of the black hole. These lobes provide evidence for powerful eruptions occurring several times over the last ten thousand years. The image also contains several mysterious X-ray filaments, some of which may be huge magnetic structures interacting with streams of energetic electrons produced by rapidly spinning neutron stars. Such features are known as pulsar wind nebulas. Chandra has detected over 3,300 individual sources that emit X-rays in this field of view. This image is the sum of 86 observations added together, representing over three million seconds of Chandra observing time.<\/p>\n<h2 class=\"wp-block-heading\">News Media
