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."

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.

Scientists discovered 13 molecules, including some never spotted before in the early universe, inside two galaxies located 12 billion light-years away.

Our solar system has been orbiting the Milky Way's black hole heart for 4.6 billion years. But it is hard to pin down exactly how many trips around the galaxy our sun has made during that time.

The early galaxy AzTECC71 is so far away it keeps disappearing from telescope observations. A new study by the James Webb Space Telescope finally pins it down.

Located about 2.5 million light-years from our solar system, Andromeda is the most distant object visible to the naked eye.

Space photo of the week The Gemini South telescope captured the chaotic aftermath of a billion-year-old collision between two spiral galaxies — and their super-close supermassive black holes.

A Milky Way doppleganger discovered in the early universe suggests some key physical ingredient is missing from cosmological models.

Several exoplanets at the edge of our galaxy could have formed continents — and advanced life — 5 billion years earlier than Earth, new research suggests.
