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 ...

SANTA CRUZ, CA — According to the prevailing “cold dark matter” theory of the evolution of the universe, every galaxy is surrounded by a halo of dark matter that can only be detected indirectly by ...

Less than 2 billion years after the Big Bang, a galaxy roughly three times the mass of the Milky Way had already stopped forming stars, settled into a bloated shape, and lost something astronomers did ...

Researchers have used the ALMA telescope and found old elliptical galaxies in the universe can form from intense star formation within early galaxy cores. An international team of researchers ...

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 ...

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 ...

Here’s how stars reveal a galaxy’s age—and what powers active cores like quasars and blazars.
