The supermassive black hole at the center of our galaxy,the Milky Way, is always up to something unusual. Now, astronomers have spotted strange new objects close by — and they aren't quite sure what they are. Using 13 years worth of data from the W.M. Keck Obser...
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 ...
Artist’s impression of a ring of cool, interstellar gas surrounding the supermassive black hole at the center of the Milky Way. New ALMA observations reveal this structure for the first time.NRAO/AUI/NSF; S. Dagnello At the center of our galaxy, approximately 26,000 light-years away, is ...
What they discovered was a very simple relationship, a relationship between the galaxy we live in and the most destructive force in the universe, a supermassive black hole. It set the world of cosmology alight. People were not that excited about supermassive black holes. The general astronomer...
More disturbingly, it meant there could be a supermassive black hole lurking at the heart of our very own galaxy, the Milky Way. Andrea Ghez has been coming to Hawaii for the last five years, trying to find out if there is a supermassive black hole in the middle of the Milky Way. ...
The researchers calculated that the black hole has already travelled about 35,000 light-years from the center, which is more than the distance between the Sun and the center of the Milky Way. And it continues its flight at a speed of 7.5 million kilometres per hour, NASA said. At this ...
The Hubble Space Telescope took this photo of the 5000-light-year-long jet of radiation ejected from the active galaxy M87’s supermassive black hole, which is aboutt 1,000 times more massive than the Milky Way’s black hole. Although black holes are dark, matter whirling into their maws ...
There's only one thing in the universe this dense. Lying at the center of this necklace of spinning stars is a supermassive black hole. You can't see it, but it's there. The most destructive force in the universe is lurking at the heart of our very own galaxy, the Milky Way. The...
The Milky Way's supermassive black hole is leaking gas By measuring the speed of stars close to the black hole, astronomers can estimate its mass. That’s how they know, for example, that the black hole at the center of our own galaxy has a mass around four million times that of the...
