I know there are different types of galaxies, so does the size of the galaxy vary according to the type? ... The biggest galaxies we know of are elliptical - but on the other hand, there are small ones, too (called "dwarf elliptical galaxies"). ...

For a long time, two different types of models of galaxy formation were common: First, "top-down" theories according to which galaxies have formed during a comparatively short period, at about the same time, within the first billion years after the universe started to expand, from an initial hot state, such as the...

Many different types of galaxies exist. The different types of galaxies not only appear different, but have different evolutionary histories as well. The three fundamental classes of galaxies are elliptical, spiral, and irregular.

Using the pictures on the worksheets, show students the different types of galaxies. These pictures will help the students get a visual feeling for the general forms of galaxies. Remind them that they cannot go outside and see galaxies without a high powered telescope.

We find that the host galaxies of different types of radio sources (compact, FR-I and FR-II) appear to have fundamentally different large-scale HI properties: the more powerful radio galaxies (Fanaroff & Riley type-II, with relativistic jets ending in bright hot-spots) often appear to show tidal HI structures,
