Two billion years our galaxy collide with the Large Magellanic Cloud
The Milky Way is in danger! A new study of astrophysicists from the University of Durham (UK) suggest that the galaxy the Large Magellanic Cloud (LMC) will face our Milky Way galaxy about two billion years, and the consequences of this collision may be much sadder than previously thought. The article describing this research was published in the journal Monthly Notices of the Royal Astronomical Society.
A few years ago, another international team of astrophysicists has been published the likely prognosis for our galaxy. It said that after 4 billion years the Milky Way will absorb the Large and Small Magellanic Clouds, and 5 billion years, he will be absorbed by Andromeda, which will lead to the formation of a giant elliptical galaxy, which the researchers called conditionally Mlekomedoy. From the findings of the last part of the whole according to most scholars. However, in the new astrophysicists Durham University study says that the collision of the Milky Way and Large Magellanic Cloud, located are now about 163 000 light-years away, there will be much earlier than you expect.
Such findings, scientists are building on the results of observations of the distribution of dark matter in the LMC. Astrophysics found that the LMC contains nearly twice as much dark matter than previously, thus it has a far greater mass than expected. This mass, in turn, affects how the LMC communicates with its neighboring galaxies.

The consequences of a collision of the Milky Way and the LMC would be catastrophic, the scientists say. A collision of two galaxies can "wake up" relatively inactive at the moment the supermassive black hole at the center of our galaxy. As a result, it will start very quickly absorbed by the surrounding gas and it will increase in size by 10 times.
"The destruction of the Large Magellanic Cloud, caused by the absorption of the Milky Way, and will seriously damage our galaxy by awakening located in its center a supermassive black hole and turning it into an active galactic nucleus or quasar", - says the study's lead author Marius Kautun.
"As a result, a black hole begins to exude a very powerful energy jets. Presumably, our solar system has to survive in this clash, but there is a possibility that the merger of two galaxies, our system will be ejected into intergalactic space, "- adds the scientist.
