The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

Astronomers have for the first time imaged the powerful magnetic fields that dwell around the supermassive black hole at the heart of the Milky Way, Sagittarius A*.

The strange behavior of hypervelocity stars suggests a nearby dwarf galaxy must contain a supermassive black hole. If so, a collision with the Milky Way is inevitable.

Sagittarius A*—the supermassive black hole at the heart of the Milky Way—is presently in a dormant state, although astronomers believe that it did have large-scale radio jets in the past.

New research shows that the Milky Way's supermassive black hole is spinning faster than we expected, dragging space-time with it.

Using NASA's James Webb Space Telescope, Northwestern astrophysicists gained the longest, most detailed glimpse yet of the supermassive black hole at the center of the Milky Way. They found the ...

Astrophysicists are marveling at the latest celestial discovery made near the Milky Way's supermassive black hole. Scientists have uncovered the existence of a binary star system close to the ...

Astronomers have detected a mid-infrared flare from the supermassive black hole at the heart of the Milky Way galaxy for the very first time, and it’s shedding new light on the complex physics ...

An image of Sagittarius A*, the supermassive black hole at the heart of the Milky Way, which scientists think is spinning as fast as it possibly can.

Observations from the Event Horizon Telescope may reveal a secret merger in our supermassive black hole's past, potentially explaining the cosmic monster's unusual spin.

Supermassive black hole Sagittarius A* is spinning nearly as fast as it can, dragging the very fabric of space-time with it and shaping the heart of the Milky Way.
