Yes, there are some irregular galaxies that are up to 150000 light years across.
Yes, there are some irregular galaxies that are nearly 13 billion light years from Earth (I.e. T2003 468 in the Ursa Major constellation).
Yes, there are some lenticular galaxies that are nearly 13 billion light years from the earth.
Yes, there are some spiral galaxies that are nearly 13 billion light years from Earth (I.e. T2003 1529 in the Ursa Major constellation).
The closest (DX Cnc) is 11.8 lightyears away. The farthest is nearly 4000 lightyears away.
Nearly all galaxies are moving away from our galaxie and planet.
The Red Shift or Doppler effect
No, the farthest galaxies from the Milky way are nearly 100000000000000 light years away.
It is hypothesized that almost all galaxies have super massive black holes in their center.
The universe is made up of millions maybe even billions of galaxies to number them all would be impossible... ----- Estimates from the late 20th century indicate 200 billion to 400 billion galaxies. More recent indications are that these numbers are probably quite low. A computer simulation from a few years ago indicated 500 billion. New data indicates that the number of galaxies we fail to find in surveys are probably nearly ten times the number that we can. It seems as time goes by the number goes up, and this is only partly because we can see farther into the universe.
Yes, there are some quasars that are nearly 13 billion light years from the earth.
Yes. There are more glaxies than just ours. The observable univers contains an estimated 100 billion galaxies. There may be other galaxies out there too, ones so distant that their light has not reached us.
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
