Galaxy's Black Hole tagged posts

Astronomers have found that a nearby galaxy’s black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC1068, a well-known galaxy with an actively feeding black hole at its center, researchers combined new infrared observations with existing data to map how the black hole’s energy is reshaping the surrounding gas. The results are reported in a paper published Aug. 6 in Astronomy & Astrophysics.

Shaping how galaxies evolve
As matter falls into supermassive black holes, it releases huge amounts of energy, driving powerful winds or outflows from the galaxy’s center. These outflows can heat the surrounding gas, expel gas and stir up the star-forming material in the galaxy, preventing it from forming new stars...

The supermassive black hole lurking at the center of our Milky Way galaxy is not as dormant as had been thought, a new study shows.

The slumbering giant woke up around 200 years ago to gobble up some nearby cosmic objects before going back to sleep, according to the study published in the journal Nature on Wednesday.

NASA’s IXPE space observatory spotted an Xray echo of this powerful resurgence of activity, the researchers said.

The supermassive black hole Sagittarius A—abbreviated to Sgr A—is four million times more massive than the Sun. It sits 27,000 light years from Earth at the center of the Milky Way’s spiral.

Last year astronomers revealed the first...
