What Is a Black Hole? Artist concept of a giant black hole: The arrows show the paths of massive objects in and around the opening of the black hole. Photo courtesy NASA Stellar mass black holes form when massive stars die. If you have read How Stars Work, then you know that ...
And at right is the more massive black hole at the heart of our own Milky Way galaxy. (NASA's Goddard Space Flight Center Conceptual Image Lab / NASA) Earth is minuscule compared to the supermassive black holes. It would take 109 Earths to span the diameter of the sun, according to ...
The compact and, with 4.3+-0.3 million solar masses, very massive objectlocated at the center of the Milky Way is currently the very best candidate fora supermassive black hole (SMBH) in our immediate vicinity. The strongestevidence for this is provided by measurements of stellar orbits, variab...
The compact and, with \\({\\sim }4.3\\pm 0.3\\times 10^6\\) M\\(_{\\odot }\\), very massive object located at the center of the Milky Way is currently the very best candidate for a supermassive black hole (SMBH) in our immediate vicinity. The strongest evidence for this is...
The second way that supermassive black holes grow is through mergers, where two supermassive black holes collide and merge together to form a single, even more massive, black hole. To track growth by mergers, the team usedIllustrisTNG, a set of supercomputer simulations that model galaxy formatio...
Our galaxy is part of a collection known as the Local Group. Because some of these galaxies are prominent in our sky, the names tend to be familiar. The Milky Way is on a collision course with the most massive member of the group, called M31 or the Andromeda Galaxy. The Milky Way is...
"The energy released, and any outflows of material, help us to understand how massive black holes shape the galaxies they live in. A big puzzle is how black holes in the centers of galaxies got to be so massive very early in the life of the universe. Studying how they accrete stars ...
The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study using data fromNASA’s Chandra X-ray Observatory and the National Science Foundation’s Karl G....

Over the past two decades, astronomers have concluded that most, if not all, galaxies host massive black holes at their centers—and the masses of a black hole and its host galaxy are correlated. But how are the two connected? Now, a University of Hawaiʻi at Mānoa Institute for Astron...
