What is a telescope? This includes the entire range of radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays. What is the electromagnetic spectrum? This is the distance between the crest of one wave and the crest of the next wave. What is a wavelength? This is a building that contains one or more telescopes. What is an observatory? This is the part of the EM spectrum you can see. What is visible light? These are imaginary patterns of stars What are constellations? This is color, temperature, size, composition and brightness. What are the star’s characterstics or how are stars classified? Astronomers use this unit to measure distances between the stars. What is a light year? This is a star’s brightness as seen from Earth. What is apparent brightness? This is brightness the star would have if it were at a standard distance from Earth. What is absolute brightness? This is what H-R stands for in H-R diagram. What is Hertzsprung-Russell? The Hertzprung-Russell Diagram has these two categories on its X axis and y axis. What are absolute brightness and surface temperature? The sun is in this section of the H-R Diagram. What is the Main Sequence? This is the color cooler stars are, like Betelgeuse. What is the color red? The brightest stars are located here on the H-R Diagram. What is the top? This is a cloud of gas and dust spread out in an immense volume. What is a nebula? This is what a star’s life depends on. What is its mass? These are the three things a star becomes when it runs out of fuel. What is a white dwarf, a neutron star or a black hole? This is the brilliant explosion of a supergiant star. What is a supernova? This is an object with gravity so strong that nothing, not even light, can escape. What is a black hole? These are the three parts of the sun’s atmosphere. What are the photosphere, chromosphere and corona? These are two forces that keep a planet in its orbit. What are gravity and inertia? This is what the gas giants are mainly composed of. What is mainly hydrogen and helium, much of which is in liquid form? This is the satellite the Soviets launched in 1957 to start the Space Race. What is Sputnik 1? The Greeks believed in this system wherein the earth was the center of the revolving planets and stars. What is a geocentric system? Make your wager These four groups of stars are labeled on the HertzsprungRussell Diagram. What are main sequence, supergiants, giants and white dwarfs?
