Galileo Galilei (February 15, 1564 - January 8, 1642) is Italian physician, mathematician as well as philosopher known as "father of modern science". His observation has brought fundamental discoveries in the field of astronomy that revolutionary shifted paradigm of viewing the universe. The Jupiter moons discovery has challenged previously accepted concept of geometric. Then, the planet movement theory became crucial milestone for Isaac Newton's mechanical theory.

The original telescope designed by Galileo in 1609 was commonly called as Galilean telescope. It used a convex objective lens and a concave eyepiece lens. This telescope produced upright images and could magnified objects about 30 times. Instead of its flaw as such as shape of the lens, Galilean telescope could view the phases of Venus, craters on the moon and the moons orbiting Jupiter.

Omega Centauri is a ball shaped cluster of stars located at Centaurus constellation. Edmond Halley considered it as a nebula in 1677. Yet in 1830, John William Herschel, a British astronomic, regarded it as a ball shaped cluster of stars. Omega Centauri is one of ball shaped clusters that can be seen through naked eyes. This brightest and biggest cluster of stars in our Galaxy consists of approximately 10 million stars with 17.000 light year (1 light year = ~ 9,5 x 1012 km) length distance from earth.
