O explain how astronomical instruments help astronomers determine the composition temperature speed

Other information in this paper will be a description of how astronomical instruments aid astronomers in determining the rotation rate of distant objects, speed, temperature, and composition also, the author will provide an explanation of the properties of stars in the hertzsprung - russell diagram. [95] astronomy is man's oldest science what he learned from it influenced him in many ways the length of the day, the phases of the moon, and the seasons of the year are governed by the orbital mechanics of the solar system ancient man observed the heavens to determine the best time for planting crops. Just recently, astronomers discovered a distant solar system, 127 light years away with up to seven planets orbiting a sun-like star called hd 10180 like the very first exoplanet 51-pegusus. 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.

Astronomical instruments are used for the purpose of study, observation, or measurement of celestial objects in the science of astronomy in order to find out the size and structure of a celestial object, observational astronomical instruments can be of great use.

Explain how astronomers might use spectroscopy to determine the composition and temperature of a star when light from a star is passed through a prism or similar device, a spectrum is produced spectroscopy is theobservation and study of these spectra.

Astronomical instruments are basically divided into two groups the first group consists of all instruments that are used for observing celestial objects, such as the telescope and other observational instruments are primarily the radiation collectors emitted by stars, planets, nebulas, and galaxies. 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. 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, find study resources. Information from astronomical spectra the key point to remember about astronomical spectra is that they provide astronomers with a wealth of detail about the physical characteristics, motion and composition of objects in this section we will examine what information can be obtained from spectra and how this is done.

O explain how astronomical instruments help astronomers determine the composition temperature speed

How do we determine what distant planets, stars etc are made of though i was stumped when trying to give a quick explanation to some friends who ridiculed the idea astronomers can know for certain what composition a distant object has the major tool in investigating the composition of an astronomical body is spectroscopy this. 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.

  • For plalnets and other objects, i believe scientists used specialized instruments, such as infrared telescopes, to determine the temperature of distant objects all the way at the bottom of this website has the star types and temps.
  • 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 objects, speed, temperature, and composition.

o explain how astronomical instruments help astronomers determine the composition temperature speed  This association is valid when considering distant galaxies and implies that some quasars are receding at 90 percent of the speed of light at a distance from earth of some 10 billion light-years thus, these quasars would be the most distant objects of the known universe. o explain how astronomical instruments help astronomers determine the composition temperature speed  This association is valid when considering distant galaxies and implies that some quasars are receding at 90 percent of the speed of light at a distance from earth of some 10 billion light-years thus, these quasars would be the most distant objects of the known universe.
