11 Best Free Linux Astronomical Data Analysis Tools

Astronomy is a branch of science that deals with the study of celestial objects (including stars, planets, moons, comets, asteroids, meteor showers, nebulae, star clusters, galaxies) and other phenomena such as gamma ray bursts and supernovae.

Astronomy is particularly well suited to the layperson. It is a wonderful hobby which has almost no age limits, it is open to individuals of all financial means, and there is always the potential for an amateur to discover something that has eluded professional astronomers, or to help monitor stars and track asteroids. Professional astronomers are in a very fortunate profession. They have the opportunity to continue their love of astronomy, travel the world, make significant discoveries, and get paid at the same time.

Professional astronomers spend far more of their time analyzing data and writing articles than actually observing celestial objects. Amateur astronomers are also keen to analyze the data they have collated. Software that can process and analyze images is therefore essential to astronomers. Fortunately, high performance scientific software has always been a strong area for Linux.

Flexible Image Transport System (FITS) is a digital file format used to store, transmit, and manipulate scientific and other images. FITS is the most commonly used digital file format in astronomy.

To provide an insight into the quality of software that is available, we have compiled a list of 11 high quality open source tools to analyze astronomical data. Hopefully, there will be something of interest here for both professional and amateur astronomers.

We give our highest recommendation to Astropy and AstroImageJ. But there’s lots of other great tools.
