Differentiate between a meteorite, meteor, and meteoroid.
meteoroid: rock in space
meteor: falling star, rock that burns up in Earth's atmosphere

Assistant to Tycho Brahe. Developed three laws of planetary motion. One law states that planets have elliptical orbits
Johannes Kepler

What happens to light as it travels away from an observer?
What astronomer is credited with this discovery?
It is red-shifted or the wavelengths of light get longer and more stretched out
Edwin Hubble

What two forces must remain balanced within a star in order for it to remain stable and on the main sequence?
Inward force of gravity balances out the outward pressure created by nuclear fusion
300

Which astronomer is well known for using telescopes to observe the sky?
radio waves, infrared, ultraviolet, x rays, gamma rays
Galileo Galilei

Describe the life cycle of a star similar to our sun from birth to death.
Created in a nebulae. Nuclear fusion begins and it remains on the main sequence for most of its life. When it runs out of hydrogen to fuse, it will expand and cool into a red giant. Then it will shrink and heat up again to become a white dwarf and eventually a black dwarf.
