Our galaxy is just an ordinary galaxy among many others.

A few astronomers have raised doubts about this extrapolation from ordinary galaxies to all extragalactic objects.

The Sun is one of 50 billion to 100 billion stars in the Milky Way, generally considered to be an ordinary galaxy.

Thus, despite their brightness, they must be more compact than ordinary galaxies.

When you are only a small planet, far out on the tip of one arm of a quite ordinary galaxy?

In the quiet, unseen, wheeling disks of ordinary galaxies, the Verity went onward.

Study better than ever before whether ordinary galaxies are responsible for gamma-ray background radiation.

The energy emitted by a quasar can exceed the total output of an ordinary galaxy a hundred times over.

Living where we do, it can be hard to tell how ordinary our Sun is, shining dimly in our ordinary galaxy.

Although other dark-galaxy candidates have previously been observed, follow-up observations indicated that these were either very faint ordinary galaxies or tidal tails.
