A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
What else can I help you with?
Are any of the galaxies moving toward earth?
Yes. Andromeida galaxy.
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
What Evidence shows galaxies are moving in relation to the earth position?
Look at the spectrum of lite from a galaxy if there is a red shift the galaxy is moving away from us or a blue shift the galaxy is coming toward us most have a red shift due to expansion of the universe we are all flying away from another
What would be evidence of a galaxy moving towards earth?
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
Is the Black Eye galaxy moving toward away or neither from Earth?
The Black Eye Galaxy [See Link] has a redshift of 0.001361, so it is moving away from us. Currently at 24 million light years from Earth
How does the sun and earth move?
They move because they are both gravitationally bound. The Sun is bound to the Milky Way Galaxy and the Earth is bound to the Sun. Another way to put it is that they revolve around each others common center of gravity. What this mean is that, in the case of the Earth, it is falling toward the Sun's center of gravity but for every foot the Earth moves toward the Sun's center, the Sun moves a foot out of the way. The Sun is moving because it is falling toward the center of our galaxy. Again, it would make it to the center of our galaxy but for one reason. Our galaxy is moving toward the center of the Virgo Super Cluster.
Are any galaxies moving toward Earth?
The Andromeda galaxy is moving towards us (The Milky Way Galaxy) at about 432,000 kph. It's expected to start merging in around 3 -> 4 billion years time.
If we saw a galaxy's light had blue shifted what does that tell us about it's motion?
If a galaxy's light is blue-shifted, it indicates that the galaxy is moving toward us. This shift occurs because the wavelengths of light are compressed as the source approaches, resulting in a shift toward the blue end of the spectrum. This phenomenon is a key piece of evidence for the motion of celestial objects and can help astronomers determine their velocities relative to Earth.
Is it true that the farther away from Earth a galaxy is the slower it is moving?
incorrect. The farther away from earth a galaxy is, the faster it is moving.
Which has a higher frequency a star moving away from earth or towards earth?
I would think that current evidence suggests that the stars moving away from earth, some of them in far distant galaxies moving at unimaginably high speeds, are going much faster than stars moving toward us. The entire Andromeda galaxy is moving toward us and will collide with us in roughly 5 billion years, and it is not moving anywhere near as fast as the distant retreating galaxies.
How do astronomers determine the speed at which a galaxy is moving?
By examining its spectrum, and identifying absorption lines in it. Lines are shifted toward shorter wavelength if the object is moving towards us. They're shifted toward longer wavelength if the object is moving away from us.
Do all-stars move?
Yes. Every star has a "proper motion", which is their motion relative to the solar system. Some stars are moving toward us, while others are moving away. Nothing is standing still. Of course, the Earth is moving around the Sun, and the Sun is orbiting the center of the galaxy, and the Milky Way galaxy itself is moving - but we can't know where. Every other galaxy is moving too, and there isn't a way to identify where the Big Bang started.
