Description
ARN (Astronomical Research Network) is a file type used to store astronomical data and information. It is typically used by professional astronomers and research institutions to store data related to celestial bodies, space phenomena, and other astronomical topics. ARN files are commonly used for research and educational purposes.
A JPEG file is an image saved in a compressed graphic format standardized by the Joint Photographic Experts Group (JPEG). It supports up to 24-bit color and is compressed using lossy compression, which may noticeably reduce the image quality if high amounts of compression are used. JPEG files are commonly used for storing digital photos and web graphics.
