Which direction are galaxies moving when they experience blue shift?
When galaxies experience blue shift, they are moving closer to us. This phenomenon occurs when the light emitted by the galaxy is compressed into shorter wavelengths, shifting it toward the blue end of the spectrum. Blue shift is typically observed in galaxies that are part of a gravitational interaction or are falling into a larger galaxy. In contrast, galaxies moving away from us experience red shift, where the light is stretched into longer wavelengths.
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.
If light from galaxies is redshifted what can astronomers conclude about galaxies?
That the galaxy is moving away from us.
Are any of the galaxies moving toward earth?
Yes. Andromeida galaxy.
In which direction are nearby all galaxies moving relative to earth?
Nearly all galaxies are moving away from our galaxie and planet.
What motion do the stars in the milky way galaxy move?
The stars in the Milky Way move in the opposite direction of the sun.
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.
Are there planets inside of galaxies?
Yes. Our own solar system is part of the Milky Way galaxy. Thousands of other systems with planets have been discovered in our galaxy. The number of planets in our galaxy alone prbably numbers in the billions.
Are all galaxies moving away from ours because your galaxy is at the center of the universe?
Other galaxies are moving away because the universe is expanding, but we are not at the centre of the universe.
What did Edwin hubble discover about the motion of the 46 galaxies?
Edwin Hubble discovered that the majority of galaxies are moving away from Earth, leading to the formulation of Hubble's Law. He observed a correlation between a galaxy's distance from Earth and its recessional velocity, indicating that the farther a galaxy is, the faster it is moving away. This discovery provided strong evidence for the expansion of the universe and fundamentally changed our understanding of cosmology.
What is the Milky Way orbiting?
There is no larger rotational group for galaxies. The Milky Way galaxy and the Andromeda Galaxy, as part of the Local Group, are moving generally in one direction, toward an unidentified central mass in the direction of the constellation Centaurus. (This may be a gravitational effect of the Shapley Supercluster.)
A decrease frequency of light from a galaxy would make the galaxy appear redder?
Yes, this is due to the redshift effect in cosmology where the wavelength of light from distant galaxies is stretched as the universe expands, causing the light to appear redder. This redshift is proportional to the distance of the galaxy, helping astronomers estimate how far away it is.
