What else can I help you with?
What is the name of the scientist that calculated the formula for the red shift?
Edwin Hubble.
Which instrument allows scientist to see the red shift?
theanswer is space probes
What determines galaxy motion and distance?
Galaxy motion and distance are determined by the expansion of the universe, influenced by the distribution of matter and dark energy. The collective gravitational forces between galaxies also play a role in their motion and organization within the universe. Measurements of redshift and luminosity distance are used to determine the distances to galaxies in the cosmos.
What does a red shift tell astronomers about stars or galaxies?
A red shift in the light emitted by a star or galaxy indicates that it is moving away from us. By measuring the amount of red shift, astronomers can determine the speed at which the object is receding and use this information to study the expansion of the universe and the distance to the object.

Which astronomer discovered the red shift?
The first astronomer to discover that a galaxies red-shift was larger the further away it was was Edwin Hubble in the 1920s.The first scientist to describe red-shift in stars was actually Hippolyte Fizeau in 1848, though he was a physicist and not an astronomer.That light should be effected in this way was suspected by Christian Doppler (after whom "The Doppler Effect" is named) as early as 1842.
When was The Red Shift created?
The Red Shift was created in 2005-06.
What is the opposite of the red shift?
The opposite of the red shift is the purple shift.
How is red-shift used today?
Red-shift is used today in astronomy to determine the distance and speed of celestial objects such as stars, galaxies, and other cosmic phenomena. It helps scientists understand the expansion of the universe and track the movement of objects in space. Additionally, red-shift is used in various fields of science to study the Doppler effect and analyze the movement of objects relative to the observer.
What equipment do scientists need to observe red shift?
Scientists can observe red shift using a spectrometer or a telescope equipped with a spectroscope. The spectrometer will measure the shift in wavelength of light emitted by celestial objects, which can indicate the red shift. Additionally, precise and sensitive telescopes are needed to capture high-quality data for accurate red shift measurements.
Can a red shift and a blue shift exist on the same object at the same time?
No, red shift and blue shift are opposite phenomena caused by the Doppler effect. Red shift occurs when an object is moving away from the observer, while blue shift occurs when an object is moving towards the observer. It is not possible for an object to exhibit both red shift and blue shift simultaneously.
Observation of the shift of a stars spectrum toward the red or blue enables us to determine the stars?
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
