If you like the astronomy then Sideralis is a magnificent application to learn about the constellations, the stars, planets… from our Nokia 5800, 5530 or X6. An application very interesting 
.
I was surprised the database that has Sideralis and the number of options that we can find. Among their options we can find the option of information where we can learn quite about astronomy.
In its official page is the latest official version, the v1.3.0, and the latest beta, the v1.3.7 b344, but i recommend to you to install
this version, the 1.3.6 b292 . We have to run it with the virtual keyboard
