What wavelengths can astronomers detect from earth?
Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.
What is extraterrestrial rock?
Extraterrestrial rock is rock that did not originate from Earth.
What are two ways the atmosphere limits what astronomers can detect?
Atmospheric absorption: Certain wavelengths of light can be absorbed by gases in the Earth's atmosphere, making it difficult for astronomers to detect celestial objects at those specific wavelengths. Atmospheric turbulence: Turbulence in the atmosphere can cause distortions in the images obtained by telescopes, affecting the resolution and clarity of astronomical observations.

How can a spectroscope be use to find out if a star is moving?
A spectroscope can determine if a star is moving by analyzing the light spectrum emitted by the star. When a star moves away from Earth, its light is redshifted, meaning the wavelengths are stretched and appear longer. Conversely, if the star is moving towards Earth, its light is blueshifted, with shorter wavelengths. By measuring these shifts in the spectral lines, astronomers can quantify the star's velocity relative to Earth.

What part of speech is extraterrestrial?

If a star is moving toward Earth it is?
If a star is moving toward Earth, it will experience a redshift in its light spectrum due to the Doppler effect. This means that the wavelengths of light will be stretched and appear more red. This effect allows astronomers to measure the speed and direction of a star's movement.
