Scientists have believed for a while now that a supermassive black hole known as Sagittarius A* sits at the center of the Milky Way galaxy. We know something is there because we’ve spotted the ...

Astronomers call it Sagittarius A*, or Sgr A* (pronounced “sadge A star”) for short, because it’s located (from our point of view) in the Sagittarius constellation. Discovering the Milky Way ...

This discovery raises the risk that the Milky Way's central black hole—Sagittarius A*—might end up producing similar jets in the future, with the cosmic-, gamma- and X-rays from such having ...

Scientists think magnetic forces of the Milky Way's supermassive black hole, Sagittarius A*, might be strong enough to push against the pull of gravity. Perhaps such tension could prevent the ...

And if the supermassive black hole in J2345-0449, which has an estimated mass equivalent to 1.4 billion suns, can erupt so violently, could our galaxy's supermassive black hole Sagittarius A* (Sgr ...

Using the data collected, astronomers were able to calculate important properties about the black hole -- called Sagittarius A* -- such as ... 27,000 light-years, and enhanced by six times the ...
