Our galaxy is surrounded by a mass of gas called the Magellanic star stream. However, its mysterious origin has puzzled astronomy for 50 years. It is thought that the Milky way had some chaotic events in its early wilderness, such as the possible annexation of another galaxy called Gaia enclados. One piece of evidence for this event, about 2.4 billion years ago, lies in the huge spherical space around the central disk of the Milky way, or “halos.”. < p > < p > astronomers first discovered the existence of this “Ribbon” in 1970 and named it the Magellanic star current. The researchers believe it was torn from two dwarf galaxies billions of years ago: the Large Magellanic and the Small Magellanic Clouds. < / P > < p > these galaxies contain billions of stars orbiting around the Milky way, and are bound by their huge gravity, completing a complete “swing” every billion years. However, joss bland hawthorn, an astrophysicist at the University of Sydney, believes that the main component of the current is “hot and cold gas”, which contains a small number of stars, making it very abnormal. This problem has been perplexing people for decades. Andrew fox, an astronomer at the Institute of Space Telescope Science, calls it a “half century puzzle.”. < p > < p > previous studies have been able to reveal the size and shape of stars, but it is difficult to assess the mass (about one billion solar masses) contained in them. However, by modeling, we can only explain one tenth of them. What is the origin of this cosmic ribbon? How did it become so huge? To solve the mystery, an international team of bland hawthorn and fox published their findings in the journal Nature on Wednesday. < / P > < p > using sophisticated supercomputing to simulate, the team thinks they can answer this question. Because previous modeling did not take into account a critical factor in explaining the missing quality. < / P > < p > because the Magellanic Nebula itself is large enough to be surrounded by hot “halo” gas (like the Milky way), it is vividly called the “megellanic corona.”. According to Thorsten teppergarc í a, an astrophysicist at the University of Sydney, this kind of halo can be seen in almost all galaxies with a mass greater than that of the Large Magellanic Cloud, combined with our understanding and prediction of the basic formation theory of the Milky way. < / P > < p > based on this, the team believes that the formation of starstreams can be divided into two stages. First of all, the Magellanic Cloud had been dancing with the Milky way for a long time before it met the Milky way, and the two surrounded each other. < p > < p > over the next few billion years, the Large Magellanic Cloud, by virtue of its own gravity, sucked cooler gas from other smaller galaxies, warming it up and creating hot gas halos. < / P > < p > then it is captured by the gravity of the Milky way, and some of the gas halos fall into the Milky way, stretched and smeared on the outer edge of the galaxy. These glowing rings also explain another factor in the formation of the Magellanic galaxy. < p > < p > in 2007, bland hawthorn and his team carried out a study that showed that when stars hit the thermal rings of the Milky way, they should have “faded out,” but that was not the case. < / P > < p > this new study suggests that the surrounding region of the Magellanic Nebula protects starstreams by pushing hot gas out of the Milky way, preventing it from colliding with and discoloring the galaxy. Bland Hawthorne said the work redefines how gas accumulates into the Milky way and forms a reservoir of future stars. Didi Qingju bicycle has entered 150 cities
