Astronomers Discover HIDDEN TROVE Of Massive Black Holes

The universe is filled with mysteries, and there are some secrets which are beyond human understanding. One such monstrous entity in space is called black hole. A black hole is a region of spacetime where gravity is so powerful nothing can ever escape not particles, not electromagnetic radiation, not even light. In recent years, NASA instruments have painted a new picture of these strange objects that are, to many, the most fascinating objects in space. Not to mention, the massive black holes found within our galaxy! So, let’s talk about them!
Welcome to Space World. In today’s video we are going to talk about a hidden trove of massive black holes found by astronomers. So, if you want to know more about it then stay with un until the end of the video.
The idea of an object in space so massive and dense that light could not escape it has been around for centuries. Most famously, black holes were predicted by Einstein’s theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than about three times the mass of the Sun, the equations showed, the force of gravity overwhelms all other forces and produces a black hole.
Scientists can’t directly observe black holes with telescopes that detect x-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself.
So, As the attracted matter accelerates and heats up, it emits x-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them – emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.
Talking about their location, Black holes are thought to reside at the center of most galaxies, including our Milky Way, holding important clues to the functioning of these giants. A group of researchers has now found a previously overlooked trove of massive black holes in dwarf galaxies. Black holes are usually detected when they actively grow by consuming gas around them, which makes them glow intensely. These black holes, the researchers believe, can offer insights into the journey of the supermassive black hole that sits at the center of the Milky Way.
The research, conducted by astronomers of the University of North Carolina-Chapel Hill Department of Physics & Astronomy, US, is expected to shed light on the origin of our galaxy’s supermassive black hole.
