galaxies

For the first time, scientists discovered a powerful 'black hole wind' that blew through a nearby galaxy for hundreds of days, crushing star formation and reshaping the galaxy. Something similar may already have happened in the Milky Way.

ESO 420-G013 is a face-on spiral galaxy with an almost perfectly round disk and an active black hole lighting up its starry guts.

New simulations show how thousands of galaxies evolve by traveling through the strands of gas, dust and stars that make up the universe's "cosmic web."

We think the universe is 13.8 billion years old, but could we be wrong? A new study of bound galaxies offers an unexplored clue.

The most sensitive image of a globular cluster, a tightly packed ball of ancient stars, has revealed a strange radio signal that could be a black hole.

The most powerful and distant fast radio burst ever seen has been tracked to a "blob" of galaxies that existed when the universe was less than half its current age.

New observations of the Small Magellanic Cloud show that it might actually be two galaxies disguised as one.

The Hubble Telescope viewed a distant galaxy whose light appears to contradict some of the most common rules of quantum physics.

While hunting for dark matter, astronomers accidentally discovered the first known stellar stream stretching between galaxies. The trail of stars is also the longest ever seen.
