A galaxy of tiny glowing dots appeared in the three-dimensional image.

Distant galaxies do not appear to be slowing down.

The galaxy appears to have been formed when two others merged over about 300 million years, he said.

Dark matter was first proposed to account for the fact that galaxies appeared to be rotating faster than their visible mass should allow.

This accounts for the observation that galaxies appear to be flying apart; the space between them is stretching.

The galaxy appears to have mostly old stars and little or no activity.

Another insight was that galaxies appeared to develop from the bottom up, not the top down.

The two galaxies will appear at almost a right angle to one another.

This unusual-looking galaxy appears to be one partner in a cosmic collision.

The early galaxies appear to be smaller, more concentrated and less regular than today's galaxies.
