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.
The JPEG XL (JXL) file extension, is a next-generation image format developed by the Joint Photographic Experts Group, combining Google's PIK and Cloudinary's FUIF formats. It supports both lossy and lossless compression, offering up to 60% better compression efficiency compared to traditional JPEG, while maintaining high image quality. Standardized in 2021, JPEG XL is designed for web delivery, professional photography, and digital printing, supporting ultra-high-resolution images, wide color gamuts, and advanced features like progressive decoding and multiple layers.
