The large cloud of dust and gas from which a star is formed What is a Nebula? The two factors that determine how bright a star appears What are distance and absolute magnitude? The stages of the lifecycle of a massive star. nebula, protostar, massive star, Red Super Giant, supernova, black hole/neutron star The chemical reaction that takes place inside a star to cause the release of energy Hydrogen fusion A large group of stars, gas and dust held together by gravity What is a galaxy? The name of the galaxy that we live in What is the Milky Way Galaxy? The most common galaxy; It is football shaped What is an Elliptical Galaxy? A galaxy that curves outward from a central hub which resembles a pinwheel What is a Spiral Galaxy? Term used to describe galaxies that don’t have consistent shapes or sizes What is an Irregular Galaxy? What is the Core? What are Sunspots? What is the Corona? What is the Chromophere? What is the Photosphere? One and a half times larger than all other planets combined What is Jupiter? The collective name for Mercury, Venus, Earth and Mars What are the Terrestrial Planets? Currently the farthest planet from the sun What is Pluto? The four gaseous giant planets What are Jupiter, Saturn, Uranus and Neptune? The most spectacular storm on Jupiter What is the Great Red Spot? This percentage of stars are “main sequence” stars What is 90% This determines how long a star lives What is “how quickly is burns energy” This measurement tool tells you that a star is moving further away. What is the “red shift”? These 2 forces must be in balance for a protostar to become a mainstream star. What are gravity and fusion? The gravitational pull is so strong in this that not even light can escape it. What is a black hole?
