Each year, NASA's Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data that have been stored in its archive.

The Chandra Data Archive is a sophisticated digital system that ultimately contains all of the data obtained by the telescope since its launch into space in 1999. Chandra's archive is a resource that makes these data available to the scientific community and the general public for years after they were originally obtained.

Each of these six new images also includes data from telescopes covering other parts of the electromagnetic spectrum, such as visible and infrared light. This collection of images represents just a small fraction of the treasures that reside in Chandra's unique X-ray archive.
