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
(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.
Also observed a supernova and proved that comets are outside the Earth’s atmosphere o Kepler – Used Tycho’s observations, derived the three laws of planetary motion Orbits of planets are
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
How does cosmology differ from astronomy? Cosmetology studies the birth and the possible deaths of the universe where as astronomy studies the actual objects in the universe What is a galaxy? How are galaxies distributed in the universe? A galaxy is a collection of billions of stars and gasses being held together by gravity. Name the different types of galaxies and their distinguishing characteristics.
Leavitt’s discovery of the period-luminosity relation for Cepheid variable stars In the early 1900’s Henrietta Leavitt’s extensive research on Cepheid Variable stars enabled her to determine the relationship between the period and luminosity of stars to determine their distance from earth. Variable stars emit lights in different intensities and are also known as “lighthouse stars”. There is a direct relationship these stars have, which has a significant role in establishing the distance from earth, of stars that are in excess of 100 light years away (Mitchell, 1976, 162). This is the relationship between luminosity and the pulsation period of these stars. With luminosity being a measure of brightness and pulsation period being the time
Spectra can tell us what makes up a star just by analyzing it. The rainbow isn’t the only thing that makes up the star spectra. If you had the ability to look into the light that comes after the color red, you will encounter the infrared light (it is the heat felt on the skin) which eventually merges into the radio section of the spectrum. On the other side of the rainbow, next to violet is a small portion called the ultra violet, which gives us sunburns and tans. You would then find the section of x-ray radiation then the deadly gamma rays.
Depending on the current temperature on the stove the only way that you would be able to make the stove burn hotter would be to raise the amount of voltage. This means that the voltage would have to be multiplied to make the stove have a larger resistance thus making the heat higher. 7. The Hubble Space Telescope can see stars and galaxies where brightness is 1/50 of the faintest objects now observable using ground-based telescopes. Use the fact that the brightness of a point source, such as a star, varies inversely as the square of its distance from an observer to show that the space telescope can see about seven times farther than a ground-based telescope.
His observations of planetary motion, mostly that of Mars, gave important data for astronomers to come, like Kepler. This helped us construct our model of the solar system we use today. The calculation that if the Earth moves then the stars are at least 700
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.
