O explain how astronomers determine composition temperature speed and rotation rate of distant objec

Triton is the coldest object that has been measured in our solar system, with a temperature of -235° c (-391° f) this rocky moon has a polar ice cap at its south pole and many other varied geologic features including volcanoes, huge cracks in the surface, and geysers of gaseous nitrogen. The closer stars will shift relative to the more distant background stars and by measuring the size of the shift, you can determine the distance to the stars this method only works for the closest stars for which you can measure the shift. These measurements of light enable astronomers to determine certain physical characteristics of objects, such as their temperature, composition, and velocity the temperature of an object is related to the wavelength at which the object gives out the most light. Include the following elements: explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram” of the cosmic perspective. A: four layers of the earth's atmosphere containing various gases make up the composition of the sky the layers of the atmosphere are divided into the troposphere, the stratosphere, the mesosphere and the thermosphere.

o explain how astronomers determine composition temperature speed and rotation rate of distant objec For more-distant galaxies, astronomers rely on the exploding stars known as supernovae like cepheids, the rate at which a certain class of supernovae brighten and fade reveals their true brightness, which then can be used to calculate their distance.

Compare eg the article galaxy's light pushes back dark ages of the universe with new record for universe's most distant object both talk about the same object and the same study, but nevertheless the first reports a distance of 155 billion light years, whereas the second says 136 billion light years. August 27, 2013 we have a number of devices to measure the speed of an object we measure moving stars, galaxies, bugs, baseballs, and perhaps most commonly, vehicles caught in speed traps on the highway. Assignment help other subject explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram” of the cosmic perspective. Astronomers can determine the mass, age, metallicity (chemical composition), and many other properties of a star by observing its motion through space, its luminosity, and spectrum respectively the total mass of a star is the main factor that determines its evolution and eventual fate.

Students investigate the dispersion of light and interpret spectra to determine the composition of an object atoms and electrons: absorption and emission luminosity and temperature of stars using the h-r diagram students explore implications of the finite speed of light and interpret observations of the distant universe. O explain how astronomical instruments help astronomers determine the composition temperature speed and rotation rate of distant objects science of stars sci/151 abstract the information contained in this paper will explain the science of the stars other information in this paper will be a description of how astronomical instruments aid astronomers in determining the rotation rate of distant. View homework help - week3 from sci 151 151 at university of phoenix sarah pountney 9/5/16 sci/151 mr conner explain how astronomical instruments help astronomers determine the composition. The composition of a planet can be determined by a hundred years ago, things were very different in astronomy our calculations of speed, size, composition, and atmosphere of distant planets were little more than a guess, but our skills have improved an incredible amount in the past century. Astronomy 103 sample final examination c rotation rate d surface temperature e none of the above a planetary nebula is a a flat disk of material around a protostar ii atmospheric composition iii temperature iv rotation period a i & ii b iii & iv c i, ii, & iii d ii, iii, & iv.

It is one of the most useful devices in astronomy, because it allows astronomers to determine the chemical composition of planets and stars, as well as to indicate the speed and direction of a star or galaxy. Astronomers can measure these shifts to determine how fast the star is moving and calculate the mass of the planet that must be tugging on it this is currently by far the most successful and widely used method for discovering extrasolar planets. In this paper i will address how astronomers determine the composition, temperature, speed, and rotation rate of distant objects i will briefly explain the properties of stars in the h-r diagram from chapter 15 of the course textbook “the cosmic perspective.

O explain how astronomical instruments help astronomers determine the composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the diagram located in the “what is a hertzsprung-russell diagram” section in ch 15 of the cosmic perspective. The major tool in investigating the composition of an astronomical body is spectroscopy this technique makes use of the fact that a body composing certain elements/compounds will shine more brightly(or less) at particular wavelengths. The large-scale structure of the atmospheric circulation varies from year to year, but the basic structure remains fairly constant because it is determined by earth's rotation rate and the difference in solar radiation between the equator and poles. Science of stars science of stars this paper is about the science of the stars in this paper i will address how astronomers determine the composition, temperature, speed, and rotation rate of distant objects i will briefly explain the properties of stars in the h-r diagram from chapter 15 of the course textbook “the cosmic perspective” i will also summarize the lifecycle of the sun and.

  • A proper astronomer here will explain this better but it is to do with light the light emitted from stars has a particular colour, and here on earth it was noted that temperatures have colours.

Include the following elements: explain how astronomers determine composition, temperature, speed, and rotation rate of distant objects o explain the properties of stars in the h-r diagram located in ch 15, “what is a hertzsprung-russell diagram” of the cosmic perspective. Rotation of the sun the sun, like most other astronomical objects (planets, asteroids, galaxies, the regions of the sun near its equator rotate once every 25 days the sun's rotation rate decreases with increasing latitude, so that its rotation rate is slowest near its poles the temperature of 15 million kelvins (27 million degrees. Spectroscopy does more than tell you the temperature and chemical composition of an object it can also reveal the radial velocity of the object as a whole, and even describe the internal motions within an object.
