By changing the scale with your mouse, you can watch the entire sky in one window and receive the detailed images of distant galaxies and nebulas in another. Just click on an interesting object and you will get the detailed scientific information about it. Our Internet site presents information about more than 500,000,000 objects in the Universe. You can directly participate in the development of this Internet website by writing an article, uploading images, creating and describing your own group of objects or simply writing on our forum.
