About the FTS format

FTS — Flexible Image Transport System (FITS)

FITS (Flexible Image Transport System) is the standard format used in astronomy for storing scientific data, images, and tables. Developed by NASA and the IAU, it is the universal format for telescope observations, space mission data, and astronomical image archives.

Common uses

  • Astronomical image and data storage
  • Telescope and space mission image archives
  • Scientific image analysis in astrophysics
  • Converting telescope data to viewable formats

About the JAR format

JAR — Java Archive

A JAR file is a ZIP archive that packages compiled Java classes, resources and a manifest into one distributable file. Because the container is plain ZIP, a JAR can be opened, repacked or converted with any archive tool — the only thing that makes it a JAR is the META-INF/MANIFEST.MF entry.

Common uses

  • Packaging a Java library or application for distribution
  • Inspecting or extracting the contents of a compiled Java program
  • Converting a ZIP of class files into a loadable JAR
  • Repacking a Minecraft mod or plugin archive
