Share A Massive Star is a star born just like an average star. What happens to a galaxy when a black hole is formed within it? Stars that are much bigger than ours follow a different cycle throughout their lifetimes. Nebula - protostar - main sequence - supernova - neutron star - black hole. https://www.storyboardthat.com/lesson-plans/life-cycle-of-a-star, *(This will start a 2-Week Free Trial - No Credit Card Needed), Hubble Snaps Sharp Image Of Cosmic Concoction, The Orion Nebula and cluster from the VLT Survey Telescope. To make a star the size of our Sun, you would need a nebula several hundred times the size of our solar system. If the remnant is more than 3 solar masses, its own gravity will overcome the fusion from its core and cause it to become a black hole. The length of a star’s lifetime depends on its mass. Teachers can view all of their students’ storyboards, but students can only view their own. Are black holes a theory of science or a fact? around the world. At this stage, the star is known as a red giant. Are black holes a theory of science or a fact? Teachers may opt to lower the security if they want to allow sharing. This ends in a large explosion known as a supernova. The end of a larger star's life is much more dramatic. What creates a black hole? Cells and Microscopes. These can produce a very beautiful phenomena known as a planetary nebula. The outer layers of the star then drift off, leaving a hot, dense core. Stars of a similar mass to that of our Sun all have a similar life cycle. Life cycles of stars All stars begin life in the same way. 2977 views In addition, any storyboard can be made “sharable”, where a private link to the storyboard can be shared externally. Smaller stars are actually more efficient with the fuel they have. While smaller stars, like our Sun, are formed by a collapsing nebula, larger stars’ nebulae contain a lot more matter. As an extension, have your students compare this life cycle with the life cycle of a star with a similar mass to that of our Sun. Nebula - protostar - main sequence - supernova - neutron star - black hole The most massive of stars (10+ solar masses) start out like smaller stars. micah hardge, quetta lindsey, jay roberts Stellar Nebulas, also known as nebulae are clouds of dust and superheated gases. They form from gas and dust in a nebula until it condenses into a protostar, when it starts to heat up and glow. After the supernova explosion, the life of a massive star comes to an end. Within the portal, all users can view and copy all storyboards. This is when the initial size of the star begins to really matter. Conception and Growth. The author can choose to leave the storyboard public or mark it as Unlisted. Though our own star, the sun, may not die for another 5 billion years about 10,000 of these nebula's are estimated to exist in the Milky Way. This will be the fate of our star in a few billion years. This means the outward pressure decreases, allowing the gravitational force to collapse in the core. Life as we know it wouldn’t exist without the Sun. Asexual Reproduction. Could the big bang have started with a black hole exploding? All storyboards are public and can be viewed and copied by anyone. This ball of gas emits huge amounts of radiation that has sustained life on Earth for millions of years, and it is categorized as a star. 1 Answer Rishab C. May 31, 2016 The difference mainly lies in what they eventually become. The average star, like our own, turns into a white dwarf. Life Cycle Worksheet. If you went into a black hole would you end up in another dimension? Stars that are stable, like our Sun, are in the main sequence stage of the star’s lifetime. Chemistry. The outer layers expand and cool slightly. Chemical Testing. Will we ever have the ability to create one? A Planetary Nebula by definition is, “ A large cloud of gas and dust in outer space ejected by an aging star near the end of its life cycle” (Science Tech-book). A white dwarf is a dead star that still shines because of the residual heat. They will also appear in Google search results. They also go through a main sequence stage but have a blue hue because of their higher temperatures. This cloud, which contains the building blocks of the star, collapses due to gravity. 6668 views Our star is relatively insignificant, as it is one of millions of stars in our galaxy, and our galaxy is only one of the billions of galaxies in the universe. Unlisted storyboards can be shared via a link, but otherwise will remain hidden. Life Cycle of a Massive Star. All storyboards and images are private and secure. A cloud of dust and gas, also known as a nebula , becomes a protostar, which goes on to become a main sequence star. Smaller stars will become planetary nebulae and then white dwarfs. Massive Star Life cycle. How does the life cycle of a massive star differ from the life of an average star? The Sun. This dead star which has cooled and no longer emits light is known as a black dwarf. © 2020 - Clever Prototypes, LLC - All rights reserved. The mass of a star depends on how much matter there was in the cloud, known as a nebula, that created the star. Supernovae are one way. They start as a nebula. If you went into a black hole would you end up in another dimension? around the world. The amount of energy produced in these reactions can be calculated from E=mc2. See all questions in Life and Death of Stars. This cooling changes the color of the star to a red color. This is also the longest phase of a star's life. Like stars of a similar mass to our Sun, massive stars also grow when they start to run out of nuclear fuel. If so, what would happen? While the cloud shrinks in size, its temperature increases as the particles that make up the cloud collide with each other. When this collapsed cloud reaches a certain temperature and pressure, nuclear fusion occurs. When the outward pressure from the nuclear fusion is balanced with the gravitational force pulling the star together, we describe the star as stable. Supernovae are some of the brightest objects in the sky. The dead stars are now known as neutron stars, and they are extremely dense. They are very dense, with one teaspoon of a white dwarf having a mass of several tons. Is it possible for the earth to be sucked into a black hole?
