The Universe is so gigantic that it expanding every single second and contains numerous galaxies and many thousands of different kinds of materials. Galaxies that filled the universe contain numerous number of different type of stars and star clusters, dark and bright clouds of gas and dust, planets, astreoids, comets, meteors and other large or small sized particles. We see that new stars form from clouds of gas and dust condensing in deep space and also they end their lives with extraordinary ways called Supernovae. Supernova explosions spread the elements, which are necessary for life and produced in the centers of the stars.

Our Universe contains colliding galaxies, clouds that reflect the light of the nearby stars, dark matter, black holes, planets and small sized objects. With naked eye we can only notice the brighter and/or the nearest objects like Moon, Venus, Mars, Jupiter and Sun. But the others…

Telescopes are the most important tools for astronomical observations. Objects that are not seen by naked eyes can be observed clearly by the telescopes. Larger telescopes make the fainter and more distant objects observable. Therefore, the distant places in the universe and the details of the celestial objects are visible with the telescopes to allow us to make the right comments.

Universe where the biggest and the smallest, the fastest and the slowest, the brightest and the most dim coexist, and which is empty, despite the incredible numbers of celestial bodies… The earth and we inhabiting it occupy a very small place in the universe. Earth revolves around the sun at a speed of 30 kilometers per second, in other words 1,800 km per minute or 108,000 km per hour. At that speed it would take 3.7 hours to go to the moon. The same speed would let us to the sun in 1,384 hours, if of course the sun does not consume us with its magnificent heat.

During daytime we have the sun, which is the source of life and we have the giant celestial sphere in the night, full of stars and planets. The celestial sphere includes an unimaginable number of planets and stars, and galaxies hosting inconceivable numbers of stars and other bodies… Like the human beings, there are stars being born and stars at the end of their lives.

The School of Astronomy invites children to discover the mysteries of the universe.
