PIX4584544: Primitive black hole - Artist view - Primitive Black hole - Artist view - Artist view of a primitive galactic black hole. The presence of 13 billion-year-old black holes was observed by the Spitzer space telescope. These distant black holes appear in the early stages of their formation; their accretion disc contains no dust. This artist's conception illustrates one of the most primitive supermassive black holes known (central black dot) at the core of a young, star-rich galaxy. Astronomers using Nasa's Spitzer Space Telescope have uncovered two of these early objects, dating back to about 13 billion years ago. The monstrous black holes are among the most distant known, and appear to be in the very earliest stages of formation, earlier than any observed so far. Unlike all other supermassive black holes probed to date, this primitive duo, called J0005-0006 and J0303-0019, lacks dust. As the drawing shows, gas swirls around a black hole in what is called an accretion disk. Usually, the accretion disk is surrounded by a dark doughnut-like dusty structure called a dust torus. But for the primitive black holes, the dust tori are missing and only gas disks are observed. This is because the early universe was clean as a whistle. Enough time had not passed for molecules to clump together into dust particles. Some black holes forming in this era thus started out lacking dust. As they grew, gobbling up more and more mass, they are thought to have accumulated dusty rings. This illustration also shows how supermassive black holes can distort space and light around them (see warped stars behind black hole). Stars from the galaxy can be seen sprinkled throughout, and distant mergers between other galaxies are illustrated in the background / Bridgeman Images
PIX4584755: Stellar black hole - Artist view - Stellar black hole - Artist view - A stellar black hole is born from the gravitational collapse of a massive star. The stellar black holes have a mass of some solar masses. A black hole is a region of space whose gravitation is so strong that it will prevent any form of material or radiation from escaping. A stellar black hole is a black hole formed by the gravitational collapse of a massive star; it is also a region of space in which the gravitational field is so powerful that nothing can escape / Bridgeman Images
