    Star Formations Every star you see at night in the sky is bigger and brighter than our sun. Stars are born within clouds of dust and gas that is spread throughout most every galaxy. The life of a star includes many stages from nebulas to the mysterious black holes. Stars are responsible for the creation and circulation of heavy elements such as carbon, nitrogen, and oxygen. The elements characteristics are informally bound to the characteristics of the planetary systems that may consolidate about them. The formation of stars is a process. Everything has to start somewhere or at some point. Stars have a starting formation. Nebulae are the starting point, the beginning of a stars life. A nebula is a visible, at night because it more illuminat…

    A star is known as “a fixed luminous point in the night sky that is a large, remote incandescent body like the sun” (Oxford Dictionary). The life cycle of a star is a very complex and magnificent process. Every star starts out as a nebula and have their own physical features. They all evolve and turn into something beautiful. Every star's physical features vary. Their diameters can range from 450 times smaller to 1,000 times larger than the sun. Temperatures expand from 3,000 degrees Celsius to…

    Thesis Statement: During their existence, stars form when the density of interstellar gas and dust, which form molecular clouds, reaches a certain point, and die by collapsing and turning into a white dwarf or a neutron star. Stars can fail and become a brown dwarf. Stars form when the density of the concentration of molecular clouds collapses and reaches a certain point. These regions are usually extremely cold and contain carbon and hydrogen. However, not all materials from the clouds form…

    Stars Lifecycle

    • 907 Words
    • 4 Pages

    A Stars lifecycle can span from millions to trillions of years depending on the size of the star. Starting from a cloud of gas and dust then transforming into something that we on earth see every day as our own Sun then finally collapsing upon itself and eventually dying. Stars have been a major part of the development of life on Earth and will continue to dictate how we live our lives. Without these enormous balls of gas and energy life as we know it would cease to exist. This is regrettably…

    Stars Vs Low Mass Stars

    • 412 Words
    • 2 Pages

    Stars are complex and giant balls of matter that have many things to understand about. Stars are born of gas and dust and have a life cycle based on their original mass. All stars start out in their main sequence, but the first difference between the mass of stars is when they stop producing energy. The low-mass stars become giant, and the high-mass stars become super giant. For low-mass, the star then becomes a planetary nebula, then finally a white dwarf. High-mass stars become a supernova, a…

    known as stars. Stars are one of the most popular astronomical objects and represents the building blocks of galaxies. A star is defined as a vast ball of gas held together by its own gravity. The nearest star to earth is the Sun. Similar to a living organism, stars have a life cycle in which they are born, they develop and grow, and eventually die. Stars begin as a vast cloud interstellar dust (mostly carbon or silicon) and hydrogen gas floating around in space. This gas can be floating for…

    and the sky and… the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it plays an important role in the universe. The street light flickers on above your head, snapping you out of your reverie and reminding you that you still have an essay to write. You sigh, sit up, and walk to your house, the…

    Cepheid Variable Stars

    • 2 Pages

    Cepheid Variable Stars are large and luminous yellow stars in space known to sporadically change size and temperature resulting in pulsing variations in brightness and thus, inconsistent levels of luminosity. There are two types of Cepheid Variable Stars; Type 1 Cepheids (or classical) which are high mass stars with smaller pulsating periods and Type 2 Cepheids which are lower mass stars with greater pulsation periods. All Cepheid Variable Stars, named after the first observed star of this type,…

    I look up to the sky and see millions of stars, and I wonder to myself. What makes them light up so bright, and what makes them a star? What does it take to create a star; they just don’t pop out and shine bright. I want to know the process, and how long it takes for a star to be born. I am also curious to know if the star can die. I plan on finding the answer. I believe that they are created by gases and that they die when they use up all of their gases. Stars have had an impact in our…

    Fewer Stars Decline

    • 2 Pages

    Our universe is fading according to a recent study done by GAMA (Galaxy and mass assembly). After surveying light from as far back as two billion years the survey found that the light in our universe is fading and will have gone black in 100 billion years. This is due to two main factors. Fewer stars (the universe's light bulbs) are being made and our universe is expanding. “More stars are dying then being born” we know this because after looking 2 billion years into the past we have seen a…
