Describe two ways in which gravity has a part in the life-cycle of a star- Gravity pulls the dust and gas in the nubula together, and compresses them so much that the inside becomes hot enough for fusion reactions to start. Gravity also pulls the remains of a red giant together after fusion reactions have stops. This forms a white dwarf. Theories about the universe- 1. What does red shift tell s about distant galaxies?
Sometimes in binary systems, mass flows into a hot accretion disk around the neutron star and causes the emission of x rays. 14. Astronomers have found compacted objects

Chapter 1 • Review the components of our solar system – sun, planets, moons, asteroids, comets and their definitions o Star – a large, glowing ball of gas that generates heat and light through nuclear fusion o Planet – a moderately large object that orbits a star; it shines by reflected light. Planets may be rocky, icy, or gaseous in composition o Moon (Satellite) – an object that orbits a planet o Asteroid – a relatively small and rocky object that orbits a star o Comet – a relatively small and icy object that orbits a star o Solar System – a star and all the material that orbits it, including its planets and their moons o Nebula – an interstellar cloud of gas and/or dust o Galaxy – a great island of stars in space, all held together
(2 points) Mars. B) Cosmic Origin of the Element CLUE: The substance collected has properties indicating that it contains a few different elements. The elements in your sample were formed in a supernova and released into space when the star exploded. Small stars and cosmic rays are not hot enough to form them. Look at the chart below to see which elements are typically formed in supernova and which ones are not.
Unit 11 – AO1 – The Universe and the Big Bang Introduction - This AO explores the parts that make up the universe and how these parts tie in to each other to make up the world we live in. Check List - This assignment requires the following tasks to be completed: 1. Features of the Universe * The Universe * The Big Bang Theory * Stars * Galaxies * Constellations * Nebulae * Planets * Asteroids * The Sun 2. Life Cycle of a Star * Explain each of the 6 stages of a star’s life cycle. Include the name given to the star for each stage 3.
These two stars are thought to be cooling and expanding on their way to becoming red giants. The second pair, around 10,000 astronomical units from the first, consists of two faint, small and relatively cool red dwarfs. The Capella
The nebular hypothesis suggest that: a. all bodies in the solar system formed from an enormous gas cloud. b. Earth’s moon is an asteroid captured by the Earth’s gravity. c. galaxies such as the Milky Way form independent of one another. d. the Earth was formed a cosmic explosion, a “big bang”. e. the moon is derived from a protoplanet.
The most logical answer is A. When the earth was just starting to form a big astoride hit earth and a large amount of material flew off to form the moon. 3. Sunlight is created from_______ a. Sun light Bulbs b. Thomas Edison c. Yo Moma d. Energy from Nuclear Fusion i. D. Sunlight is the energy that is released when a nuclear reaction causes hydrogen to form in to helium 4.
