What is a FITS file?

FITS files store images, tables, and metadata in a structured, extensible manner. The format is platform-independent and widely used in scientific communities, especially astronomy, for preserving the fidelity of data.

Its capability to store complex scientific data makes it invaluable for researchers who need precise, reliable information. FITS is not user-friendly for casual use.
