SUMMARY
The Chandra X-ray Observatory's ACIS CCD chip has a field of view of approximately 17 arcminutes by 17 arcminutes. When considering the size of the Moon's disc, approximately 30 ACIS CCD chips can fit across it. If an X-ray source fills a single CCD at a distance of 500 parsecs, the object measures about 1.5 kilometers across. This calculation is essential for understanding the scale of astronomical objects observed by Chandra.
PREREQUISITES
