For the first time, astronomers have traced a fast radio burst (FRB) to the outskirts of an ancient, dead, elliptical galaxy—an unprecedented home for a phenomenon previously associated with much ...

More recent work, however, casts doubt on the certainty that the two galaxies will clash, eventually forming a single, ...

It might appear featureless and unexciting at first glance, but NASA/ESA Hubble Space Telescope observations of this elliptical galaxy—known as Messier 105—show that the stars near the galaxy's center ...

Seen from Earth, the giant elliptical galaxy M87 is just a two-dimensional blob, though one that appears perfectly symmetrical and thus a favored target of amateur astronomers. Yet, a new, highly ...

The Puzzle of Early Galactic Giants In the standard picture of galaxy formation, large halos of dark matter form first. Their ...

The vastness of space allows for a huge variety of structures to pop up all over the place. Even things we think of as one-and-done objects—like galaxies—come in quite a few shapes and sizes. You’ll ...

It is as humbling as it is motivating to think about how much we still have to learn about the universe. My collaborators and I have just tackled one of astrophysics’ enduring mysteries: how massive ...

Ohio University astronomers have discovered the largest disk of hot, X-ray emitting gas ever observed in the universe: At 90,000 light years in diameter, it’s about 100,000 times the size of any ...

An intense demolition derby of at least six galaxies smashing into one another has been found lurking in the early universe by the James Webb Space Telescope.

Astronomers first detected the new FRB, dubbed FRB 20240209A, in February 2024 with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). For the first time, astronomers have traced a fast radio ...
