Scientists have suggested a new threat to the Solar system

Ученые предположили новую опасность для Солнечной системы

The large Magellanic cloud can throw the Solar system from the milky Wayin About 5 billion years the big and beautiful spiral galaxy Andromeda will collide with the Milky Way, writes the Chronicle.info with reference to Hvilya

However, one of the smaller neighbors of our Galaxy – the Large Magellanic cloud – face with her for about 2.5 billion years before. A study published in the journal Monthly Notices of the Royal Astronomical Society, according to Naked Science.

“The destruction of the Large Magellanic cloud with the Milky Way absorption wreaks havoc in our Galaxy, awakening black hole in its center and turning our Galaxy, to active galactic nucleus or quasar, says lead study author Marius Cowton from the Institute of computational cosmology of Durham University. This phenomenon will produce powerful jets of high-energy radiation coming directly from the vicinity of the black hole.”

The researchers note that these jets will not affect the Solar system. Despite the fact that gravitational interaction caused by the merger can throw us out into intergalactic space, the chances of this are very small. Distances between stars are so great that even a galactic collision is not likely to push our system out of the Galaxy.

The large Magellanic cloud a satellite galaxy of the milky Way, located about 163 thousand light-years from it. Astronomers have not previously considered a dwarf galaxy as a likely candidate for the collision, assuming the fast-moving Large Magellanic cloud will continue to rotate around the milky Way for eons of time.

However, recent observations suggest that the satellite galaxy is twice more dark matter than previously thought, which significantly increases the calculations of its weight. And this, in turn, entails serious consequences for the future of this galaxy and ours.

“Even despite the fact that at the moment the Large Magellanic cloud is moving away from the milky way, dynamical friction, influencing the heavy galaxy will lead to a rapid loss of energy of its orbit, and after about a billion years it will turn around and will go to the center, where for about 1.5 billion years will merge”, the researchers explain in their paper.

Obviously such a collision will increase the mass of the milky Way. Supermassive black hole Sagittarius a* will be about eight times more massive, but the glowing “halo” of the outskirts of our Galaxy will become more massive than approximately five orders of magnitude, according to computer simulations, researchers.
