    • Celestial Bodies & Pulsars By Ryan Lacy, Laura Hayes, & Michelle Stewart
    • What is a Pulsar?Pulsars are Neutronstars that emitbeams of light &radiation that shootout at opposite ends.Since Pulsars rotateon an awkward axis,This explains why wesee it blink on andoff.
    • DiscoveryPulsars were discovered in1967 by astrophysicistJocelyn Bernell while shewas conducting graduateresearch. She discovered itwhen she noticed radiofrequencies were blinkingon and off.
    • How do Pulsars relate to Earth & Space?Pulsars relate to the CLEAcomputer program lab we didabout pulsars. Explaining whatscientists do when they find oneand how they interpret them.Generally, pulsars are also one ofthe many celestial bodies that westudy in space.
    • How are Pulsars important to Earth & Space? It tells us more about the nature of stars and act as probes to let us investigate the universe. They were deemed important around the time of its discovery because they thought it was extra terrestrial life sending messages out into the universe. It was proven later they were just another breed of stars.
    • StarSStars are in a sense ball of gas The properties of starsthat burns to make there were discovered by Ejnarsignature illuminating effect. All Hertzsprung and Henriettaheld together by gravity. Leavitt throughout the 19th century. Mizar and Alcor. The binary star system Polaris that is part of “The Big Dipper”Stars were first constellation.recognized by theancient Egyptianscirca 2,500 A.D. Betelgeuse. The star on Orions left shoulder.
    • Nebulas B33 Orion NebulaNebulas are a cluster ofgases, stars, and dust.Most common are aresult of the death ofstars. Eagle NebulaContains necessarymaterials to make stars,planetary/solar systems,and other celestialbodies. The life givingphenomena. Eskimo Nebula
    • CometsComets are chunks of iron androck, much like asteroids, with aice filled core. The ice is mostlikely from other sources such asplanets from the universe that Haley’s Comet. A comet webroke off. are familiar with when it fly’s by Earth every 75 years. The thing that makes comets comets is when it flies by a heat source, such as the Sun, Shoemaker-Levy 9. A comet that was and the ice starts to melt discovered in 1993. In 1994 it broke up making a misty tail of water into fragments by Jupiters gravity and vapor that in some pictures crash into Jupiter making craters the size of Earth
