Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."

Active galaxies are thought to be powered by?
Active Galaxies are thought to be powered by rotation
How a galaxies differ from a star?
a galaxy is billions of stars
What are some ways in which galaxies differ?
habitats can differ temperture,moisture,and many other ways.
Two types of what galaxies are barred and normal?
the two types of galaxies that are barred and normal would be irregular as my best guess
How are black holes involved in understanding active galaxies?
It is difficult to ask black holes about how they are involved in active galaxy research because they cannot talk, this makes them only peripherally involved in understanding active galaxies
What are active galaxies powered by?
A central, supermassive black hole.
What are the release dates for Astronomy Observations and Theories - 2005 Active Galaxies 1-14?
Astronomy Observations and Theories - 2005 Active Galaxies 1-14 was released on: USA: 21 June 2006
How does red shift differ between galaxies close to us and ones which are further away?
Generally, the galaxies that are further away will have the larger red shifts.
What two types of galaxies are described as barred and normal?
SB and SA are two types of galaxies which are described respectively as barred and normal. Both types fall within the spiral form which galaxies may assume. S and SA more specifically qualify for the classifications of ordinary or unbarred within the spiral form of normal galaxies while only SB receives the categorization of barred type of normal, spiral galaxy.
What two types of galaxies are barred or normal?
The type of galaxy that is Barred and Normal is the Spiral Galaxy.
What are some ways galaxies are different?
habitats can differ temperture,moisture,and many other ways.
How is know that active galaxies have small core regions?
It is known that active galaxies have small core regions because we can see them in images! These small regions known as uassars emit perful amounts of both radio waves and gamma rays...
