... If one looks at this region with big telescopes and nearinfrared cameras one can see lots of stars. If one takes pictures every year it seems that some stars are moving very fast (up to 1500 kilometers per second). The fastest stars are in the very center - the position marked by the radio nucleus ...

Chapter 16 Lesson 2: What is a Star
... New stars form in a nebula which is a cloud of dust and gas pulled together by gravity. 1. The temperature rises, hydrogen changes into helium, and the particles release energy; the particles become a star. b. A star can use up all of its hydrogen and helium and die. 1. The center of the star may sh ...

Formation of Stars
... Stars form from contracting lumps of gas and dust located within cold molecular clouds. Within these molecular clouds, gas and dust is able to cool, slowly converting their energy-of-motion into infrared radiation, which then escapes into interstellar space. These contracting clumps are termed proto ...
