Astronomers mapped the distant galaxies to study the universe's large-scale structure.

The artist decided to galaxy the mural, sprinkling tiny painted worlds across its surface.

We lay on the hill and watched the galaxy pour a faint, silvery river across the night sky.

Early astronomers often spoke of the Galaxy as though it were the only island of stars, unaware that countless others lay beyond it.

During the survey, we identified three jellyfish galaxies with long ionized gas tails.

Active galaxies often outshine their host galaxies, making it challenging to study the surrounding stellar populations.

Energetic jets and strong emission lines make Markarian galaxies important targets for studying active galactic nuclei.

Astronomers found that the dense cluster contained several elliptical galaxies whose stellar populations showed surprising similarities.

Irregular galaxies often have chaotic structures that tell astronomers about past interactions.

Astronomers often compare lenticular galaxies to spiral and elliptical types when classifying galaxy morphology.
