The History of Astronomy
... Galileo’s experiments showed that objects in air would stay with a moving Earth. • Aristotle thought that all objects naturally come to rest. • Galileo showed that objects will stay in motion unless a force acts to slow them down (Newton’s first law of motion). • The planets COULD move about the Sun ...

Some of these experiments were tried, but they failed to determine a speed of light since the distances used were too small (a few miles). It was not until 1676 that an actual measurement of the speed of lig ...

Stars and Their Characteristics
... Death of a Star (size of the sun) • remain same size (main sequence) for billions of years because energy produced through fusion equals gravitational pull • hydrogen is used up so gravity takes over, which then produces heat by contraction • entire star expands (Red Giant) • core temperature rises ...

How Is a Star`s Color Related to Its Temperature? - d
... On a clear night you have surely noticed that some stars are brighter than others. But stars also have different colors. Rigel is blue, and Betelgeuse is red. Capella and our sun are yellow. In this activity you will make your own HertzsprungRussell diagram. You will see how star brightness, color, ...
