STATES CHRONICLE – Everything we knew about the enormous appetite of a black hole was shaken this month as a black hole was found to emit gas. The phenomenon is located fairly close to our galaxy, a mere 26 million light years away. Researchers are currently analyzing this new data.
A black hole is a phenomenon that occurs when a star, such as is the case of our Sun, depletes all of its resources and implodes. The result of the implosion is a black hole, an event horizon that engulfs everything around it. The “hunger” is due to the impressive amounts of gravitational pull that the phenomenon exerts.
Because of this increased gravity, until these recent findings, researchers concluded that nothing can escape the gravitational pull of a black hole. Not even the small particles that compose a beacon of light. Because a black hole was found to emit gas, supporters of the Big Bang theory have now additional proof that an explosion caused by a black hole stands at the roots of the Universe.
The phenomenon is possible because the gas that was engulfed by the event horizon expanded. The outer regions of the black hole are significantly colder than the inside, making the gas escape, searching for the colder parts. This is one of the explanations given by researchers.
Another possible cause for this “leak” could be the fact that the galaxy at which’s core stands the black hole in question has interacted with a neighboring galaxy, one of bigger proportions. The interaction led to the assimilation of a very big quantity of gas, which ultimately caused the emissions. New stars are in the process of forming due to these gases leaking.
Eric Schlegel, the leading researcher at NASA, has said that this type of behavior must have been normal at the time in which our galaxies were formed. The materials emitted possibly being responsible for some alterations to the Universe that we know today.
The observations and measurements were made with the help of the X-rays taken by the Chandra telescope at NASA, and the optical images supplied by the National Observatory from Kitt Peak.
The gas arcs observed were surrounded by a cloud of hydrogen gas, suggesting the fact that the gas emitted by the black hole was hot, and this attracting the cooler hydrogen clusters.
Scientists at NASA have decided to call the strange phenomenon “feedback” because it is a reaction caused by the interaction between a galaxy and a black hole.
As earlier mentioned, the “feedback” is nothing but good news for the Big Bang theory enthusiasts, because it is clear evidence that a black hole cannot only destroy, but also create.
