Gaia Sky is a free, open-source and cross-platform (based on Java) 3D astronomy visualization software developed by ZAHUniversität Heidelberg from Germany. It is designed to map about 1 billion fixed stars in the Milky Way where our planet is located, based on the framework of ESA‘s Gaia mission, and supports VOTable, FITS, CSV and all formats supported by the STIL library.

With the help of DR2 data, Gaia Sky has been able to achieve a comparatively ideal use effect. This is what makes astronomy enthusiasts so happy. Gaia Sky 2 is based on the Gaia satellite data, and has become the most comprehensive and accurate digital map of stars in the solar system and Milky Way galaxy so far. And its ambition is not small, because it also contains local galaxy clusters and some SDSS data, and it is not clear whether it wants to make a star map of the whole universe in the future. Besides, Gaia Sky 2 even includes the location data of some nearby galaxies. It can be scaled as far as showing a slice and the Planck & CMB image of the larger structure of the universe, which represent the boundaries of our current understanding to the universe.

If you are an astrophile and really want to draw your own star map or something like that, then I recommend Gaia Sky to you, which is very worth a try. This powerful and easy-to-use 3D visualized star map drawing software enables you to easily map almost any number of stars. Especially, you are free to move and zoom in the stars in this star map as you wish.
