they are moving in all directions away, toward, sideways relative to EarthNearly all galaxies are moving away from the Earth. This is because the universe is expanding.
no
Nearly all galaxies are moving away from our galaxie and planet.
The Red Shift or Doppler effect
Yes, there are some lenticular galaxies that are nearly 13 billion light years from the earth.
Measurements of Doppler shift indicate that nearly all of the galaxies outside of our own cluster are moving away from us.
No, the farthest galaxies from the Milky way are nearly 100000000000000 light years away.
Yes, there are some spiral galaxies that are nearly 13 billion light years from Earth (I.e. T2003 1529 in the Ursa Major constellation).
It is hypothesized that almost all galaxies have super massive black holes in their center.
The clock on train B would appear to be the same width and to run at the same rate
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
comparatively, nearly, approximately
Nearly all spiral galaxies, including our own, have such a feature.
A super massive black hole.
