Why is the light reaching us from some celestial object shifted toward the red or blue end of the spectrum?
Due to something similar to the Doppler effect. A wave reaching us from an object travelling towards us will look shorter than the same wave from an object travelling away from us. In light shorter waves gets bluer end longer waves get redder.

What information can you learn about a celestial object just by measuring the peak of its black-body spectrum?
By measuring the peak of a celestial object's black-body spectrum, you can determine its temperature. The peak wavelength or frequency is inversely proportional to the temperature of the object. This measurement helps in understanding the object's physical properties and can provide insights into its composition and behavior.
What is the relationship between how red-shifted a spectrum is and how fast the object is moving away?
The redshift of a spectrum indicates that an object is moving away from an observer, and the degree of redshift is proportional to the object's velocity. This phenomenon, known as the Doppler effect, occurs because as the object moves away, the wavelengths of light are stretched, shifting them toward the red end of the spectrum. The greater the redshift, the faster the object is receding. This relationship is often quantified using the redshift parameter ( z ), which can be related to the object's recessional velocity through specific equations in cosmology.
How can you tell the absorption lines in the photographic spectrum?
Absorption lines in a photographic spectrum appear as dark lines where specific wavelengths of light are absorbed by elements in a celestial object. These lines indicate the presence of elements in the object's atmosphere and can be identified by comparing their positions with known spectral lines of elements on Earth.
What is the violet shift?
The violet shift refers to the shifting of spectral lines towards shorter wavelengths in the spectrum of a celestial object. This can occur when an object is moving away from an observer. In the context of cosmology, it is a key piece of evidence supporting the expansion of the universe.
What is the celestial equivalent of latitude?
The declination of a celestial object is the exact equivalent of latitude.

A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant obect we say that the object's spectrum is?
A spectral line that appears at a wavelength of 321 nm in the laboratory appears at a wavelength of 328 nm in the spectrum of a distant object. We say that the object's spectrum is red shifted.
Is cloud a celestial object?
No. A celestial object is an object in outer space, such as a planet, star, meteor or comet. Clouds are not in outer space, therefore they are not a celestial object.
What celestial object is about 24000 miles from the earth?
There is no celestial object at that distance.
This is the change in color on the spectrograph as objects move toward or away from objects?
This phenomenon is known as the Doppler effect, where the frequency of light waves emitted by a moving object appears shifted depending on whether the object is moving towards or away from the observer. This shift in frequency causes a change in color on the spectrograph, with objects moving towards us appearing blueshifted (shifted towards the blue end of the spectrum) and objects moving away appearing redshifted (shifted towards the red end of the spectrum).
Analyzes an object's spectrum?
A spectrometer analyses an object's spectrum.

How do you calculate red shift?
The spectrum of light emitted from heated hydrogen has dark lines, caused by the absorption of a very narrow wavelength band of light. These dark lines always take the same location relative to each other. If all the lines in an object's spectrum are shifted by the same amount, towards the red end of the visible spectrum, then the light is "red shifted." The amount of the shift is often described with a number 'z', where z equals the shift in wavelength divided by the wavelength as originally emitted by the object.
How can you tell the absorption lines in the photographic spectrum?
Absorption lines in a photographic spectrum appear as dark lines where specific wavelengths of light are absorbed by elements in a celestial object. These lines indicate the presence of elements in the object's atmosphere and can be identified by comparing their positions with known spectral lines of elements on Earth.
