24. Asteroids, Comets, And Meteors Theme Page CLN menu page provides links to science curricular resources and instructional materials(lesson plans) in the specific topic of asteroids, comets and meteors. http://www.cln.org/themes/asteroids.html

Asteroids, Comets, and Meteors Theme Page This "Theme Page" has links to two types of resources related to the study of asteroids, comets and meteors. Students and teachers will find curricular resources (information, content...) to help them learn about this topic. In addition, there are also links to instructional materials (lesson plans) which will help teachers provide instruction in this theme. Please read our Asteroid and Comet Impact Hazards "Although the annual probability of the Earth being struck by a large asteroid or comet is extremely small, the consequences of such a collision are so catastrophic that it is prudent to assess the nature of the threat and prepare to deal with it." This NASA site provides basic information about such possibilities including government reports and FAQs about impacts, asteroids and comets. Build Your Own Comet Advice and a recipe for building a six inch comet. The site also provides basic information about comets. Constellation Prizes In this lesson plan, grade 6-12 students "learn about meteors, meteorites, and comets by reading and discussing a related New York Times article about the Leonid meteor showers and the methods that scientists are using to learn from these meteors. Students then create and observe a comet in their classroom."

He has encouraged amateur astronomers and advised many U.S. governmental and scientific agencies. CREDIT: ALLAN BURCH A s an Iowa farm boy, I contracted a case of polio and it prevented me from becoming a professional tennis player. When I entered the University of California at Los Angeles, it was still my main ambition to excel at tennis. A mathematics major enabled me to bring home good grades without having to spend much time on studies. But I never made the tennis team. In my junior year, I shifted from mathematics to astronomy because the course Frederick C. Leonard gave had intrigued me, and this determined my career. Subsequently, he obtained a teaching fellowship in astronomy at the University of California at Berkeley for me. After earning my Ph.D., I accepted Harlow Shapley's offer to head Harvard College Observatory's observing program. My interests, besides computing comet orbits and looking for new comets on the photographic platesI found sixincluded galaxies, but the institute's director made it clear by subtle means that this area of research was not for me.

36. .:: Vallis Alpes : Comets & Meteors ::. Such random meteors are termed sporadic. Occasionally, though, the Earthcrosses the orbit of a comet and encounters a dense swarm of dust. http://www.apsylus.com/vallis-alpes/comets.html

Comets are insubstantial bodies, loosely knit assemblages of frozen gas and dust that loop around the Sun on highly elongated orbits. They return to the inner Solar System at intervals ranging from a few years to many thousands of years, becoming visible to us on Earth as ghostly, glowing apparitions for a few weeks or months before receding back into obscurity. Our Galaxy has two small companion galaxies called the Magellanic Clouds. To the naked eye they appear like detached portions of the When far from the Sun, a comet shines only by reflecting sunlight. At that stage it is small usually no more than a few kilometres across and faint. Approaching the Sun, the comet warms up, turning its icy surface into gas. Under the influence of the Sun's radiance the gases of the comet begin to fluorescence, in similar fashion to the gas in a neon tube, thereby considerably increasing the comet's brightness. Gas and dust released from the warming comet produce a halo or coma 100,000 km or so in diameter. At the centre of the coma is the nucleus, the only solid part of the comet, consisting of a "dirty snowball" of ice, dust and perhaps some rock. In a large comet the nucleus may be a few tens of kilometres across, but most are only a kilometre or so wide. Well over a thousand million comet nuclei would be needed to equal the mass of the Earth. Not all comets develop tails, but many do. One part of the tail consists of gas blown away from th comet's head by the solar wind of atomic articles streaming from the Sun. The other part of the tail is made up of dust particles liberated from the head by the evaporating gases. Comet tails always point away from the Sun. A comet's tail can extend for 100 million km or so, further than the distance from the Earth to the Sun, as did the gas and dust tails of Comet Hale-Bopp in 1997. Yet, for all its glorious appearance, the tail is less dense than a laboratory vacuum stars shine through it undimmed. The tail of a comet gives it the appearance of speeding across the sky, but actually its movement against the stars is barely noticeable during the course of a night.
