As this material falls into the black hole, it emits X-rays. X-ray image of Cygnus X-1 taken from orbiting Chandra X-ray Observatory Photo courtesy NASA/CXC In addition to X-rays, gigantic black holes can also eject materials at high speeds to form jets. Many distant galaxies have ...
This artist’s concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies. Image credit: NASA/JPL-Caltech At the core, millions of tonnes of hydrogen are being converted...
Astronomers have observed objects called quasars, which glow brighter than thousands of galaxies put together and are thought to be powered by supermassive black holes consuming matter. Quasars have been seen back as far as the first billion years after the Big Bang, when our universe formed, ...

of mysterious Intermediate-Mass Black Holes (IMBHs). These are objects with masses between a few hundred and tens of thousands of solar masses, which could represent the link between their smaller relatives, stellar black holes, and the supermassive giants that populate the centers of galaxies. ...
–How many galaxies are there? –Hubble’s law: Why are most galaxies moving away from us? –How black holes and galaxies play tug-of-war across the cosmos As the gas collapsed and its density increased, some stars formed very early on, before the gas had stabilised into a rotating disc...
Yet how they formed and evolved into their various shapes remains a mystery. When astronomers look into the deepest reaches of the universe with powerful telescopes, they see myriads of galaxies. The galaxies are far away from one another and constantly moving away from one another as our ...
from Chapter 4 / Lesson 14 7.4K Supermassive black holes are located at the center of galaxies and are formed with the formation of a galaxy or over time. Explore the central engine in the galaxy, x-rays, jets, and their connection to supermassive black holes. Related...
