Deep inside the Milky Way, an invisible force is quietly holding everything together — its magnetic field. Now, researchers have created one of the most detailed maps ever of this hidden structure, ...

For nearly a century, astronomers have known that the universe is expanding. Most galaxies are carried outward with the flow ...

A team of astronomers led by Dr. Anna Ordog at the University of Calgary has identified a magnetic-field reversal slicing ...

The Milky Way is not the serene, flat disc that textbook illustrations suggest. Astronomers have confirmed that the outer edges of our galaxy’s disc are warped and that this deformation rotates slowly ...

The center of the Milky Way is an extreme place. In addition to housing our galaxy's supermassive black hole, it also contains a 700-light-year-wide region of dense gas called the Central Molecular ...

Scientists using the ALMA telescope have created the most-detailed-ever map of the Milky Way's chaotic center. The observations could open a window to the ancient universe as it appeared shortly after ...

Sagittarius A* may be a dense dark matter core instead of a black hole, offering a new explanation for the Milky Way’s central gravity.

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

A new radio survey reveals that the Milky Way’s magnetic field is intricate, widespread, and deeply connected to how the galaxy is organized.

Our understanding of the galaxy has advanced with every leap in the number of stars. From early observations to more and more advanced space and ground-based telescopes, each milestone has revealed ...
