What else can I help you with?
How can you tell that some galaxies are far away and moving rapidly towards us?
You can tell by the blueshift in the spectrum; the only reasonable explanation for this blueshift is the Doppler effect. - Please note that most galaxies are moving away from us, not towards us.
How did scientists belived that distant galaxies were rapidly moving away from the earth?
Scientists believed that distant galaxies were rapidly moving away from Earth primarily due to the observation of redshift in their light spectra. This phenomenon, known as the Doppler effect, indicated that as galaxies move away, their light shifts toward longer wavelengths (red). Edwin Hubble's observations in the 1920s showed a correlation between the distance of galaxies and their redshift, leading to the formulation of Hubble's Law, which demonstrated that the universe is expanding. These findings provided strong evidence for the Big Bang theory and transformed our understanding of the cosmos.
How are galaxies moving today?
galaxies are movign further away from eachother
What is the Doppler shift of galaxies?
It shows how galaxies are moving in relation to Earth.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
How many galaxies are approaching milky way galaxy and how many are moving away related to the cosmological red shift?
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
How do galaxies move?
they move by not moving.
How fast are galaxies moving away from each other in the expanding universe?
Galaxies in the expanding universe are moving away from each other at speeds proportional to their distance, with more distant galaxies moving faster. This phenomenon is known as the expansion of the universe.
Why is it that Andromeda is moving rapidly towards your solar system when the universe is meant to be expanding?
The Universe as a whole is expanding but that doesn't mean everything has to be moving apart. Galaxy clusters are moving away from one another, but galaxies, stars, and planets aren't. Gravity still has a strong grip on everything.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
The fact that the light from distant galaxies is red-shifted suggests that the galaxies are?
Moving away from us
In which direction are mostly all galaxies moving?
Actually, most galaxies are all moving away from all other galaxies, not just from ours. The exception is the Andromeda galaxy, with which the Milky Way is on a collision course.
