NASA's Chandra X-ray Observatory has amassed a staggering "back catalog" of cosmic recordings that are impossible to replicate. The observatory's data, spanning nearly two decades, have been compiled into the Chandra Source Catalog (CSC), a vast repository of X-ray information.
The CSC contains over 400,000 unique compact and extended sources, as well as more than 1.3 million individual detections in X-ray light. This treasure trove of data allows scientists to combine Chandra's X-ray observations with information from other types of light, such as visible and infrared radiation.
One striking example of the CSC's wealth is a new image of the Galactic Center, the region around the supermassive black hole at the center of the Milky Way galaxy. The image spans just 60 light-years across and features over 3,300 individual sources that emit X-rays, detected during 86 observations spanning three million seconds.
To help visualize this vast dataset, NASA has released a sonification β a translation of astronomical data into sound. This new representation encompasses 22 years of Chandra observations across the sky and offers a unique glimpse into the mission's history.
In the sonification, each detection is represented by a note that changes over time to reflect repeat observations. The resulting soundscape provides an immersive experience, mapping out the distribution of X-ray sources across the galaxy.
The CSC can be accessed online at https://cxc.cfa.harvard.edu/csc/, offering scientists and the public alike a wealth of information about Chandra's cosmic recordings. NASA's Marshall Space Flight Center manages the observatory's program, while the Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science operations.
