Convert PNG to FITS

The Portable Network Graphics (PNG) file extension, established in 1996, serves as a widely-used raster graphics format that supports lossless data compression. Initially developed as a superior, patent-free replacement for the GIF format, PNG is prevalent in the IT industry for web design, digital photography, and complex graphics due to its capability to handle detailed images with transparent backgrounds and its extensive color range. Known for maintaining high-quality visuals without increasing file size significantly, PNG remains an indispensable tool in professional digital imaging and web development.

The FITS (Flexible Image Transport System) file extension is widely utilized in the field of astronomy for storing, transmitting, and manipulating scientific data and images. Originating in the late 1970s, FITS was developed by NASA and the International Astronomical Union (IAU) to standardize the format for astronomical data. Its primary use is to archive astronomical images, spectral data, and other multidimensional data arrays, enabling efficient data interchange among scientists and astronomers. FITS files are known for their ability to store metadata and large datasets, making them essential for detailed scientific analysis and long-term preservation in research environments.
