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

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

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

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

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.

Astronomers use deep surveys to study dwarf galaxies to better understand how dark matter is distributed.

Astronomers discovered that many spiral galaxies contain supermassive black holes at their centers.

Radio galaxies often host relativistic jets that extend far beyond their host galaxies.
