The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the ...

Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to ...

The James Webb Space Telescope’s first picture released to the public showed off thousands of galaxies. At first glance, the pinpoints of light shining in the blackness of space look like little stars ...

In 1963, Caltech researcher Maarten Schmidt had a eureka moment. He was looking at the spectrum of a mysterious object named 3C 273, a source that had been found and cataloged with then-novel radio ...

Astronomers have spotted a pair of galaxies in the act of merging 12.8 billion years ago. The characteristics of these galaxies indicate that the merger will form a monster galaxy, one of the ...

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. Follow ...

At the heart of nearly all large galaxies lies a supermassive black hole (SMBH). Some of these black holes may be steadily feeding on surrounding gas and dust, while others lie incognito with barely ...
