    Essay On Nebulae

    • 640 Words
    • 2 Pages

    Nebulae are cosmic clouds of dust and gas floating in space. The word nebula is Latin and means cloud. Originally the word nebula referred to any extended astronomical object, not including comets, planets, or satellites. But over time the word nebula became reduced to mean interstellar cloud of dust and gas. Calling it that does not do a nebula justice. Most nebulae are commonly made up of hydrogen and helium gasses, dust, and plasma. Nebulae are the building blocks of our universe; they contain

    its life. Nebulae are the first stage in a star’s life cycle. Nebulae act as the nursery of the universe. A nebula is a massive cloud made of dust and gas. They can stretch light years across and have a very fuzzy appearance. The primary gases found in a nebula are hydrogen and helium gases. Not all nebulae are the same. They can range from blue to red to pink in color, and can be shaped like crabs, eagles, or just a large ball of dust. There are several types of nebulae. Emission nebulae are nebulae

    planetary nebulae Procedure The first part of the experiment involved using a picture of a church and back round to understand different pixels, ADU, zoom, and how to get the (x,y) coordinates. We then took this brief understanding of pictures and applied it to the stars. We loaded a picture of nebulae m42. After this we needed to calculate the average number of stars or solar masses. We found the (x,y) coordinates of a position in the center of the nebulae and on the edge of the nebulae. We used

    gave speeches regarding “The Scale of the Universe”. Shapley believed that the Milky Way is large and we are not at its center. He also believed that spiral nebulae are small gas clouds included in the Milky Way. Whereas, Curtis believed that the Milky Way was small and we are toward the galaxies center. He also believed that spiral nebulae are external galaxies comparable to the Milky Way. Curtis theory was based on Kapteyn’s, with the unawareness of dust absorption. Shapley argued that because

    in space made of dirt or so called dust. Galaxies are groups of billions of stars, planets, dirt, and other matter put together by gravitational force people call gravity. Nebulae have many ways of forming in which galaxies do not. Nebulas come in galaxies, emission nebula, reflection nebula, planetary nebulae, dark nebulae, open clusters. As for galaxies come in spirals, irregular and elliptical shapes. Here are some examples of shapes and what they look

    priority to comet seeking. A by-product of their search was the discovery of many bright nebulae. Several catalogs of special objects were compiled by comet researchers; by far the best known is that of the Frenchman Charles Messier, who in 1781 compiled a catalog of 103 nebulous, or extended, objects in order to prevent their confusion with comets. Most are clusters of stars, 35 are galaxies, and 11 are nebulae. Even today many of these objects are commonly referred to by their Messier Catalog number;

    This paper will talk about the Planetary Nebula. The name came from a man called William Herschel. He called the sphere shaped clouds a planetary nebula because it is round just like a planet is. The word Nebula comes from the latin word Nebulae or Nebulas which means cloud. This paper will also consist of different information about the stars and life “cycle” of the stars. A Planetary Nebula is formed when a star's outer layers are blown off and they expand into space which would soon form

    struggled to determine the true size of our universe, as well as the nature of nebulae. Two competing ideas arose: the “island universe” hypothesis and a single galaxy hypothesis, as described by Harlow Shapley. The “island universe” hypothesis suggested that each nebula was its own galaxy like the Milky Way, while the idea of a single galaxy said that the Milky Way was much larger than estimates of the time and all nebulae were part of the galaxy or clouds outside of it. These two opposing views were

    clusters were observed to be concentrated towards one half of the sky. Also, the distances of the variable stars implied that the globular clusters were far away. (3) He believed that Milky Way was so large that it was the entire Galaxy (4) Spiral Nebulae were just gaseous clouds located within our Milky Way. He modeled this by observing the globular star clusters. (Zabludoff, 2012) Previously, the distance to one of the prominent globular cluster called M13 was determined by an astronomer and from
