Some new changes:

Now, 3D vies have 2 different modes for exoplanets (A galaxy like simulation) and Asteroids (The solar system type simulation. Solar system because all data on asteroids are present for near Earth asteroids).
Now, Universe Data Booklet have study (Flashcards, Quiz, Compare etc.) and research section (Specific details key point study).

There are more updates. To see all of them and Try please wait until 10 August (I will deploy the site and Update it that day.). But the source is available in the repository. Those who are interested can give it a try directly from source code (But the source code is in early state and un-stable. So, I can not guarantee anything).
