Computers and astronomy have always been well-matched partners. While the huge amount of data available in astronomy today and repetitive calculations would be taxing for humans to manipulate manually, they present no such difficulty for modern computers.
That's why there is a great selection of astronomy software, covering everything from trivial tasks like calculating the positions of Jupiter's four main moons, up to taxing simulations of the whole Universe. Amateur astronomers have a rich library of applications to choose from - some are commercial, costing anything from a few to several hundred pounds, but many options are free.
In this article we will look at a few of these 'freeware' applications, many of which have been around for a while. The test of time has seen these pieces of software refined to a point where, once used, they can become an integral part of the observing experience. Although our list is not exhaustive, we hope it will help you discover some of the incredible free astronomical programs out there.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
