“Oh, be a fine girl/guy kiss me,” or maybe not. Learning this phrase has helped multiple astronomers to educate themselves on the spectral classification of stars and continues to do so in today’s time. Annie Jump Cannon’s legacy will carry on lasting a lifetime! The first letters of each word in the phrase represents the seven main types of stars. Starting with ”‘O,” these stars are very young, blue, hot, massive and extremely bright star. This type of star is very uncommon similar to the “B” and “A” stars. These stars get their energy from nuclear fusion, as they convert Hydrogen to Helium. As these massive stars begin to die once they’ve worn out their hydrogen and are now very old stars, they turn into giants/supergiants (old, large stars), resting just above the main sequence stars. This is where the “F” and “G” stars are located. The hotter they are, the brighter they are demonstrating the Sun being a G star. Next, the core contracts as the outer layers expand. This is leading to the explosion of stars eventually becoming a planetary nebula or supernova, …show more content…
Cannon’s interest in astronomy started then. Cannon started her study on physics and astronomy at Wellesley College, which was one of the top schools for women at the time. It was doing her college years that she learned spectroscopy, which became the establishment of her categorizing stars. During this time, she had gotten sick with scarlet fever leading to her becoming completely deaf, likely due to the fever. Even so, she managed to graduate with a bachelor’s degree in physics in 1884, returning home to Dover, Delaware. At the time with such limited career paths for women, Cannon learned photography. She even traveled to Europe in 1892 to take pictures of the solar eclipse. When her mother passed in 1894, she begins a teaching role in physics at Wellesley College with one of her former teacher’s Sarah Frances

    Also, the star reaches levels to where it can now have helium converted to carbon. This energy begins to drastically increase the size of the star, resulting in the creation of a red giant. Oddly enough, the color red, which is associated with hot, isn’t really in this case. The color of the star is a result of the surface temperature decreasing causing wavelengths to emit a red color, while the hotter the star is the color would be more blue. Stars don 't spend much of their life in this stage.…

    The Atomic Model

    Fusion is when two atomic nuclei combine to form a heavier nucleus which results in the release of many photons. The photons released are the light that we see. The light produced in this reaction can have any wavelength. In the case of stars, a reaction of deuterium (basic nuclei) and hydrogen (basic atom) produce a helium atom with a photon which is seen as the main source of the illumination of the star. In the end, we are able to see that stars are made up of atoms through the use of spectral lines and our knowledge of fusion.…

    Nuclear Fusion Essay

    Well, heat, a type of energy, is produced through nuclear fusion. Throughout a star’s life, nuclear fusion is what produces heat to prevent itself from collapsing. However, this process of nuclear fusion ends at some point and the force of gravity overpowers the force from nuclear fusion, causing the star to collapse (“Fusion”). Nuclear fusion is when two atom’s nucleus is combined to make a new atom. However, this process take extreme amount of energy since the nucleuses will always try to push each other away since they both have a positive charge.…

    Jupiter, on the other hand is made almost entirely of hydrogen and helium 4. Because of its large size, Jupiter loses heat very slowly. The planet is still slowly contracting. Contraction converts gravitational energy into thermal energy. Neptune also uses contraction as a way of generating internal heat.…

    A nebula is a cloud of interstellar gas and dust. According to Nola Taylor Redd contributor of space.com “4.6 years ago, the solar system was a cloud of dust and gas know as a solar nebula. With the rise of the sun, the remaining material began to clump up. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium from the closer regions, leaving only heavy, rocky materials to create smaller terrestrial worlds like earth.…

    Also the universe was considered infinite at one point in time but the Big Bang proved that the universe had to have a history and a beginning. (2)According to Chris LaRocco and Blair Rothstein article 15 billion years ago there was an explosion called the Big Bang that created the universe. This explosion contained all the matter and energy of space. Unlike other explosion like a bomb that throw fragments outwards the Big Bang filled in the space with particles of the embryonic universe. Before the Big Bang galaxies were clustered together but the explosion created space and foundation for the universe.…

    Dangers Of Solar Winds

    The sun is the star we are orbiting, which gives us heat and more stuff. Of course, it is also potentially dangerous, it can cause skin cancer, solar winds, too much heat, and it will obviously end up destroying the earth in a few billion years. I am especially studying the solar winds, this is because I think that solar winds are more interesting than the others because they look as if they were more fun and had more things to talk about. The problem with solar winds is that they come to the earth from the sun and they are highly charged and can take down electric systems and can maybe even kill humans. Of course, we have a magnetosphere which protects us from this danger, but not completely, there are still dangers like when the solar winds…

    The solar nebula grew hotter and denser, forming a disk of gas and dust at its center. Thus, the particles of nebula dust started to stick together, forming masses that eventually formed planets and their satellites. As a result of this, the energy released by the collision between particles was converted into heat. The process…

    Astronomy in Yosemite The Sun The sun is a star located at the center of the universe, and without it, there would be no life on Earth. It is the most important source of energy for humans as it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals. From satellite images of the sun in space, it appears to be a great, red, fiery ball of energy.…
