History of Caglow

Did you know that the Caglow project was originally focused on caves? Yes, it was a site all about those holes in the ground with pointy spikes and other weird formations. It has certainly come a long way since those days and a lot has changed though plenty has stayed the same. But one thing has changed for sure: no more caves!

  • August 16, 2007: Caglow is up for the first ever. Well, not quite. We weren't Caglow yet...we were a wiki for caves with nothing mentioning astronomy. But we were definitely here.
  • March of 2008: The original Caglow website (powered by TikiWiki) is launched. By this time, Caglow had shifted its focus towards computer software and development.
  • December 21, 2008: Aciqra becomes the first project to become a part of the modern Caglow platform. It saw a massive boost of popularity after making it onto the front page of SourceForge shortly after it was created.
  • July 12, 2009: The current Caglow website is set up and at put at its current domain, "".
  • December 31, 2009 The I programming language, which now forms backbone of Caglow projects is publically released.
  • Jan-Feb of 2010 The Caglow website is brought offline by a server failure. It is brought back online on February 28 after a change in hosting providers.
  • January 1, 2011 The Aciqra License is completed as v1.0.
  • December 21, 2011 Caglow 2 (2.1) is completed with the release of Aciqra 2.1.
Our Mission

To build a comprehensive and open platform for free and open source astronomy software used by those who observe and study the real sky.

This is our ultimate goal of what all work by us will be done to achieve. It is the primary target of every individual project and forms the backbone of the entire project. While the text may be changed and updated over time, the overall idea will remain the same.


This site and overall project is made possible by countless people who have reported bugs, submitted code or reviewed our individual projects. Also important are the many organizations around the world which have built up a free and open software platform from which we have built on top of.
