During the latest meeting of the AAS (Astronomical American Society), astronomers have presented a new important discovery for those researching the events that led to the creation of the Universe. A black hole in nearby galaxy was caught passing gas that it had previously swallowed. A black hole is basically a limited region in space-time where the power of gravity is enhanced to such a degree, that even the small particles of light cannot escape. Because of this immense gravitational force, the black hole has a tendency to swallow everything that comes in contact with it, thus expanding its volume.Such an event takes place when a star, like our Sun, collapses at the end of its life cycle. The discovery of the gassy black hole is even more important since, upon measuring, astronomers have determined that it is of medium size. This means that before becoming such a gravitational phenomenon, the hole was once a dwarf star that engulfed a dwarf galaxy. Such findings are the four leafed clovers of Astronomy.
The observations were made using the X-ray telescope, Chandra, located at NASA. The telescope sighted two X-ray emission streams at a distance of 27 light years from Earth. Their point of origin is located in two different galaxies that are at the point of merging with each other, “the Whirlpool”, as astronomers call this rare phenomenon.The scientific explanation of why a black hole in nearby galaxy was caught passing gas is that some of the matter that was swallowed by the immense gravitational pull escaped into the cooler region of the surrounding space. Astronomers have compared this with the ways in which a snowplow functions.Also, latest discoveries in the astronomical field have shown that a black hole is not only capable of engulfing all the matter that is surrounding it, but also it may be able to eject matter, as well. The streams that Chandra detected may be resulting from the merger of the two galaxies, the process allowing one of the supermassive black holes involved to regurgitate some of the accumulated gas.
These findings are of very high significance for those who study theories as the Big Bang. The premise in these theories is that the Universe was created after matter escaped from a black hole, thus causing a great explosion that dispersed matter in the Universe.Both scientists and astronomers are using this unique astronomical event to further deepen their studies. The article was also published in the November issue of the Astronomical Journal.
