False What are the parts of a comet? NucleusĬoma Which of the following is NOT found in the Milky Way galaxy's galactic halo? The sun Which of the following is the correct order of the components of the Milky Way galaxy, from outermost to innermost? Galactic halo, thick disk, thin disk, extreme disk, black hole. Oval/ellipse/circle If we could observe comets during their entire orbit, we would see that they have a tail throughout the entire trip. True Comets have orbits that are int eh shape of an exaggerated _. True There are two types of spiral galaxies, plain spiral and spiral barred galaxies. Spiral Galaxies have been classified in three categories depending on the tightness of the arms and the size of the central bulge. What cosmic accident is believed to form many irregularly shaped galaxies? Two galaxies colliding. True What happens to the shape of an elliptical galaxy as you move from E0 to E7? They go from round/spherical to an oval/oblong shape. Quasars Elliptical galaxies are made up of old stars, containing small amounts of gas. Galaxy Some of the most distant, and therefore oldest, objects in the universe releases energy billions of stars. Nebulae An enormous collection of billions of stars, gas, and dust held together by gravity. Astronomical Unit The name given to many indiscernible objects in space now know that these are galaxies, dust clouds, star clusters, etc.

Light year The distance from the Earth to the sun is one _, or AU. Probes When satellite images are analyzed a unit called the pixel is key to calculating what? Land area One pixel represents Land area of 30 by 30 meters Which of the following is typically NOT a method scientists use to determine astronomic distances? The size an object in space appears One _ is the distance light travels in a year. Which of the following could be considered remote sensors? Telescopes This makes satellite images more of a graph if anything Think about the definition of remote sensing. Explain why this image is often not a true 'picture'? It is not a true picture because the images are displaying information rather than just shapes and colors. False When a satellite collects information from the surface of the earth, the data is converted to an image. False Which of the following would not be considered a satellite? Halley's Comet Optical telescopes are designed to collect and create images from White or visible light Light travels in waves and require some 'medium' or substance to travel through. This noise can be collected and studied using a _ telescope Radio The branch of science that is related to the examination of the electromagnetic radiation from a star, galaxy, or another object in space is called Spectroscopy Satellites are sent out into space to make 'fly bys' of planets, moons and objects in the outer solar system.

Sputnik Which of the following would be an appropriate use for a probe? A study of the planet Saturn, its rings, on to Jupiter and some of its moonsĪ mission to study Venus, then Mercury, and into the Sun Astronomers believe that background radiation is left over noise from the big bang. Space exploration The launch of the Russian satellite, _, in 1957 began the space race between Russia and the United Sates. Rockets have been used in which of he following areas? Warfare Which type of telescope would we use to study new stars inside the giant gas cloud and why? We would use a radio telescope to be able to key into a certain frequency range and observe the stars. The longer the wavelength, the lower the energy of the wave. What is the relationship between the wavelength of electromagnetic radiation and the energy of the wave? The shorter the wavelength, the higher the energy of the wave.
