NASA's Chandra X-ray Observatory has accumulated a vast repository of cosmic recordings that defy replication. The newly updated "Chandra Source Catalog" (CSC) contains over 400,000 unique celestial sources and 1.3 million individual detections in X-ray light, offering scientists unparalleled access to data gleaned from more than 22 years of observations.
The CSC is a treasure trove of information that spans precise positions on the sky to details about the energy spectra detected by Chandra's advanced technology. This wealth of data enables researchers using other telescopes – including NASA's James Webb and Hubble Space Telescopes – to combine X-ray observations with insights from other types of light.
A striking example of the catalog's capabilities is a recent image of the Galactic Center, which reveals over 3,300 individual sources emitting X-rays within a span of just 60 light-years across. This representation is the result of 86 combined observations and represents an incredible three million seconds of Chandra observing time.
The CSC has also been sonified – or translated into sound – to provide an immersive experience for those familiar with astronomical data. The sonification encompasses 22 years of Chandra observations, capturing the repeat X-ray sightings over time through distinct notes.
A recent visual representation, similar to a map showing the Earth's geography, displays the core of the Milky Way galaxy at its center and the Galactic plane as a horizontal line across the middle. Each detection is represented by a circle whose size corresponds to the number of detections in that location over time. A year counter appears at the top of the frame, with an additional message "and beyond" indicating that Chandra continues to collect observations.
The CSC can be accessed through the NASA Chandra website. The mission is managed by NASA's Marshall Space Flight Center, while the Smithsonian Astrophysical Observatory's Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.
