Debian Astro: An open computing platform for astronomy
  Debian Astro is a Debian Pure Blend that aims to distribute the available astronomy software within the Debian operating system. Using Debian as the foundation has unique advantages for end-users and developers such as an easy installation and upgrading of packages, an open distribution and development model, or the reproducibility due to the standardized build system.
